Als der fränkische Astronom Simon Marius im Jahr 1612 erstmals sein Fernrohr auf einen nebligen Fleck im Sternbild Andromeda richtet, kann er noch nicht ahnen, was er da eigentlich sieht: Marius beschreibt „schimmernde Strahlen, die um so heller werden, je näher sie dem Zentrum sind.“ Den Lichtglanz im Zentrum erscheint dem Astronomen wie „wenn man aus großer Entfernung eine brennende Kerze durch ein durchscheinendes Stück Horn betrachtet“. Damit ist wohl Simon Marius der erste Astronom, der den Andromedanebel durch ein Fernrohr beobachtete. Spätere Beobachtungen mit besseren Fernrohren und Teleskopen ergeben, dass dieser Andromedanebel spiralförmig ist. Und im Jahr 1912, fast genau dreihundert Jahre nach Simon Marius, richtet der Astronom Vesto Slipher sein Teleskop gen Andromedanebel und findet dabei heraus: Dieser recht hübsche Spiralnebel kommt mit Karacho auf uns zugeflogen: Slipher ermittelte für den Nebel eine sogenannte Radialgeschwindigkeit von 300 Kilometern pro Sekunde. Heutzutage wissen wir, dass der Andromedanebel überhaupt kein Nebel ist – sondern eine eigenständige Sterneninsel. Sie ist also eine Galaxie genau wie unsere Milchstraßeund wie sie ein Teil der Lokalen Gruppe, gehört somit zu unserer unmittelbaren kosmischen Nachbarschaft. Die Andromedagalaxie ist derzeit rund 2,5 Millionen Lichtjahre von der Milchstraße entfernt. Allerdings: Diese Entfernung wird immer geringer, denn wegen ihrer hohen Radialgeschwindigkeit scheint es so, als würde die Andromedagalaxie direkt auf die Milchstraße zufliegen. Deshalb gilt es seit fast einem Jahrhundert eigentlich als ausgemachte Sache, dass die Andromedagalaxie und die Milchstraße irgendwann zusammenstoßen und miteinander verschmelzen werden: Aus den zwei Spiralgalaxien würde so eine einzige, größere elliptische Galaxie werden. Und doch war und ist noch vieles unklar bei dieser potenziellen kosmischen Kollision: Wird es einen frontalen Zusammenstoß geben? Oder eher eine Art Streifschuss? Oder fliegt die Andromedagalaxie auch einfach an der Milchstraße vorbei? In dieser Folge erzählt Franzi von der lange erwarteten Verschmelzung der Milchstraße mit der Andromedagalaxie – und was diese mit galaktischer Eschatologie, Tangentialgeschwindigkeiten und Messunsicherheiten zu tun hat.

As our fourth season draws to a close, we've got an apocalyptic, 2-part ending lined up. That's right, we're talking Armageddon, and we don't mean the 1998 Bruce Willis blockbuster. And of course, if we're going to delve into the end of everything, Dr. Charles Liu and co-host Allen Liu are going to need the help of our ever popular archaeology expert and author, Hannah Liu, MEd. As always, though, we start off with the day's joyfully cool cosmic thing, the failed Soviet-era Kosmos 482 lander that was designed to withstand entry into the Venus atmosphere but never actually let Earth orbit and finally just came crashing back home on May 10, just a few days after we recorded this episode! Chuck, Allen and Hannah ponder the possibilities of cataclysmic destruction that the more than half-ton object could produce. Then, without missing a beat, Hannah takes us all the way back to Greek mythology and the Titanomachy, the legendary fights between the Gods and the Titans that were possibly inspired by catastrophic volcanic eruptions that laid waste to the ancient Mediterranean. Chuck jumps continents to discuss the Norse apocalypse known as Ragnarök – casually dropping that is inspired the massively popular Baldur's Gate 3 as he does. Not to be outdone, Hannah brings us all back to the original Armageddon itself: the final battle between good and evil that is foretold in the Book of Revelations to take place at Har Megiddo, the “Hill of Megiddo” in Hebrew. You'll also hear about where the word apocalypse comes from, and why it's become associated with the end of the world, as Hannah gives us all a quick lesson in eschatology, or the study of the end of the world. Our first question comes from Ahmed, who asks, “What are the odds that a killer asteroid will kill us all?” Allen gets a little excited about asteroid 2024 YR4, an asteroid the size of a 15-story building, that is predicted to pass safely by Earth in 2032 but at one point had as high a chance of hitting us as 4-5% – and still has about a 3% chance of hitting the Moon. Chuck explains that the odds of a true “dinosaur-killer” extinction event asteroid impact from an object at least a mile across is about 50 million to 1 in any given year. Hannah points out that it's far more likely that Mount Vesuvius, the volcano that inundated Pompeii, will erupt again. The last one was in 79AD, and since it tends to blow its top every 2,000 years or so, we're due. Moving back further, Hannah tells us about the Minoan Eruption that devastated the isle of Santorini in the Mediterranean, wiping out the city of Akrotiri, around 1600 BCE and was reported as far away as China. And that's just a few of the disastrous historic collapses Hannah shares with us, including the Hekla 3 eruption in Iceland that had may have had something to do with the Bronze Age Collapse. It turns out that the apocalypse is too big for a single episode! Join us in two weeks for Part 2 of our journey into all things apocalyptic.

Who are the “Redshift Wranglers” and what can they tell us about the evolution of our universe? To find out, Dr. Charles Liu and co-host Allen Liu welcome back astrophysics PhD candidate Sadie Coffin from the Rochester Institute of Technology whose focus is galactic evolution, and in particular, the spectroscopy of galaxies and their lights. As always, though, we start off with the day's joyfully cool cosmic thing: the Lucy spacecraft fly-by of asteroid 52246 Donaldjohanson, which was named after the American paleoanthropologist who discovered the Australopithecus afarensis “Lucy” fossil the spacecraft was named after. Then it's time to learn a little about Sadie, who explains how questioning the unknown is what drove her to study astronomy. Chuck, Allen and Sadie talk about the awe embodied in the study of the universe and the universe itself. Like Chuck, Sadie studies galaxy evolution, but Sadie focuses on a galaxy's light, spread into spectra, and dissecting different features in that light. You'll hear about the citizen science project called “Red Shift Wranglers” that helps Sadie sift through all the spectroscopic data, and get an awesome explanation of the doppler effect and the way red shift, which measures speed, can be used to help build better maps of galactic evolution. Find out how you can get involved with the project and join the ranks of the 3,500 Redshift Wranglers who've participated so far in “Wrangling galaxies and the universe together.” (See below for links.) You'll also hear about other citizen science projects on Zooniverse like Galaxy Zoo. Sadie talks about the value of non-experts engaging with experts in a community, and the surprising number of people who want to get involved. For our first audience question, Nina asks, “If nothing can go faster than the speed of light, why can galaxies have Z greater than 1?” Sadie's explanation gets pretty technical, so we'll let her do it in the episode. Our next question comes from Jerry, who asks, “Will we someday no longer need scientists and have AI do all our research?” Sadie, who gets similar questions all the time relative to citizen science, believes these two things can be complimentary, and that in the name of improving science we can't forgo either for the other. We finish with a discussion about what defines an act of science and a work of art, the process of questioning, and the roles of humans and machines in these processes. Plus, Sadie tells us about the science-themed travel posters by Dr. Tyler Nordgren on her walls. Chuck also gets Sadie to talk about rowing and the lessons she's taken from the sport into other aspects of her life and journey as a scientist. If you'd like to know more about the Redshift Wrangler project on The Zooniverse and get involved, or to reach Sadie, visit https://www.zooniverse.org/projects/jeyhansk/redshift-wrangler or find Redshift Wrangler on Facebook and X (Twitter).   Listen to the COSMOS project episode referenced in this show with Dr. Jeyhan Kartaltepe, an astronomer and professor at the Rochester Institute of Technology.

Something really weird happened out in space, and astronomers are totally baffled. A strange cosmic explosion lit up the sky, and it might be a super-rare event where everything lined up perfectly — or it could be something completely new that no one's ever seen before! It's called EP240408a, and it was first spotted by the Einstein Probe, an X-ray space telescope, on April 8, 2024. At first, it looked like your typical gamma-ray burst, which usually blasts out insanely bright X-rays. But the more scientists looked, the more things didn't add up. Now everyone's wondering if we just witnessed something brand new in the universe! Credit: CC BY-SA 4.0 https://creativecommons.org/licenses/...

NASA just picked up something super weird — a haunting howling sound coming from a black hole, and no one knows exactly what to make of it.

Populatie III sterren zijn op dit moment nog een hypothese. Maar astronomen zijn er wel naar op zoek, omdat ze een missende schakel representeren in onze kennis over de geschiedenis van het heelal.

Zgodnje vesolje je bilo precej drugačno, kot smo si še včeraj zamišljali. Zvezde in galaksije so bile večje in svetlejše, nastajati pa so začele mnogo prej, kot smo domnevali. Že v središčih najzgodnejših galaksij najdemo tudi orjaške črne luknje, kar povsem spreminja naše razumevanje, kako so ti nenavadni pojavi nastajali. Ob določenih pogojih je mogoče opazovati posamezne zvezdne kopice, torej večje skupke zvezd znotraj mlade galaksije, kot je na primer galaksija, imenovana Roj kresničk, ki jo raziskuje prof. dr. Maruša Bradač. Opaziti je mogoče celo eno samo posamezno zvezdo, kot je primer zvezde Eärendil. Vsa ta nova odkritja in z njimi kup svežih ugank je prinesel vesoljski teleskop Jamesa Webba, naslednik legendarnega Hubbla. Kakšna spoznanja se nam zdaj s tem odpirajo, preverjamo v tokratni Intelekti. Gosta sta astrofizika prof. dr. Maruša Bradač in prof. dr. Tomaž Zwitter s fakultete za matematiko in fiziko Univerze v Ljubljani. Foto: Galaksija Roj kresničk je na Webbovi fotografiji razpotegnjena črta na sredini posnetka.

Nov. 13, 2024Dr. Dan Coe (Space Telescope Science Institute)The Webb Telescope was designed to look back in time, to study the first generation of stars, and reveal our cosmic origins. Now in its second year of operation, JWST has already brought us tantalizingly close to our dream of seeing those first stars. Dr. Coe takes us on a tour of some of the  latest results from the telescope, and tells us about his and others' observations of the most distant stars and galaxies astronomers have ever seen, providing a view of the universe as it was 13 billion years ago.Dan Coe is an Astronomer at the Space Telescope Science Institute (STScI) and Johns Hopkins University in Baltimore. STScI is home to JWST mission control and science operations, where staff scientists like Dan support other astronomers using Hubble and JWST. Dan has also led the Hubble RELICS and JWST Cosmic Spring science teams in discovering and studying some of the most distant galaxies known in the early universe. 

STScI Education and Outreach Scientist Dr. Chris Britt discusses time traveling to the origins of the universe with The James Webb Space Telescope.In this episode, Chris tells us about processing JWST's data into breathtaking images, groundbreaking discoveries, how stars are formed, black holes, and the telescope's future. This one is going to be cool!This episode will follow up on our previous conversation about building the JWST, so if you missed that, check out episode 14!Key Takeaways:Chris was first inspired to go into aerospace after seeing photos from the Hubble Space Telescope. Now, years later, he is a part of the team operating the Hubble!The Space Telescope Science Institute helps operate the Hubble, James Webb, and eventually the Nancy Grace Roman Space Telescope.STScI uses colors and filters in order to identify specific parts of JWST's photos like elements, matter, heat, and more.JWST will be able to see back 13.5 billion years, possibly unlocking the secrets of the universe's origins.Webb is researching our galaxy and planets as well as black holes, exoplanets, stars, etc.JWST will not be able to confirm if there is life on other planets, but it will tell us if a planet has the materials to support life.Webb will continue to work with the Hubble and someday the Roman Space Telescope, photographing the universe for years to come.Resources:Space Telescope Science Institute Website James Webb Space Telescope Website Webb Telescope Latest News (NASA)

How do you go from a small town in Colorado to being a scientist-astronaut candidate in Australia? And how can you make space accessible for disabled astronauts? To find out, Dr. Charles Liu and co-host Allen Liu welcome scientist-astronaut candidate Celene Shimmen.   As always, though, we start off with the day's joyfully cool cosmic thing, the new study using the James Webb Space Telescope that disproves the detection of tryptophan, a complex amino acid, in the interstellar cloud IC 348. Or, as Chuck jokes, no sleepy turkeys in space.   Then we get to meet Celene Shimmen, who is a scientist-astronaut candidate in Australia. She's a physical therapy student who is already putting her research to work in the space industry.   Celene describes how she recently designed and implemented the Lower Extremity Motor Coordination Test in Microgravity for AstroAccess, a project she works with dedicated to promoting disability inclusion in human space exploration by paving the way for disabled astronauts. (You may remember Cady Coleman talking about working with AstroAccess in our recent episode, Sharing Space with Astronaut Cady Coleman, Part 1. You'll hear about Celene's acceptance into the scientist-astronaut training program for suborbital missions with the International Institute of Astronautical Sciences, beginning in 2023. She tells us about her upcoming parabolic flight where she'll be the principal investigator testing balance differences after acute exposure to weightlessness. Chuck asks whether the “Vomit Comet” is aptly named – Celene explains that she'll have to let us know, since her upcoming flight will have 16 periods of microgravity. Our first question comes from Anne, who asks, “What are some psychological or physical traits that make for a good astronaut?” Celene highlights the importance of training for strength, endurance, balance, and cardiovascular fitness, especially for upcoming, long-term missions on the moon. It turns out that while the moon has lower gravity, the encumbrance of spacesuits requires greater strength and endurance. Allen explains that lesser gravity doesn't mitigate some aspects of force and inertia that also require physical strength. Celene describes the psychological aspects of being an astronaut, and the need for mental resilience to cope with isolation and stressful situations, as well as problem solving skills and the ability to work as part of a team. You'll also find out about Celene's journey from growing up in a single-wide trailer in a town of 1000 residents in Colorado to studying hospitality in the Disney College Program in Florida, where she met her Australian husband. After watching “First Man”, the movie about Neil Armstrong, Celene decided she wanted to get into the space program. She applied to and was accepted by the Melbourne Space Program, working on a nano-satellite program. She also helped a humanoid robot take its first step, which inspired her to get involved with physiotherapy and the human body in space. Our next question is from “anonymous”: What part of the human body is most vulnerable in space? Celene explains that extended exposure to microgravity leads to muscle atrophy and bone density loss, which is still a big issue even with ongoing exercise. Even just a 14-day stay in space leaves returning astronauts with muscle weakness. Finally, we hear about Celene's desire to be deployed to the moon, should the opportunity arise. Upcoming lunar missions to the moon will likely last about 30 days each, including 7 days of activity on the lunar surface. If you'd like to reach out to Celene and chat, you can follow her on Instagram @spaceptcelene and on LinkedIn and Facebook as Celene Shimmen. You can also find out more about AstroAccess here.

Saturn's "spoke season" is a fascinating phenomenon that happens on its rings. These spokes are mysterious, dark, radial features that appear on Saturn's rings, resembling the spokes of a wheel. They show up when Saturn's equinox is approaching, which is about every 15 Earth years. Scientists think they might be caused by Saturn's magnetic field interacting with ring particles, but they're still not entirely sure. It's one of those cool space mysteries that keeps astronomers scratching their heads and looking up in awe.

NASA's James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and while indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high-energy emission from the probable young neutron star have been detected.Supernovae – the explosive final death throes of some massive stars – blast out within hours, and the brightness of the explosion peaks within a few months. The remains of the exploding star will continue to evolve at a rapid rate over the following decades, offering a rare opportunity for astronomers to study a key astronomical process in real time.Supernova 1987AThe supernova SN 1987A occurred 160,000 light-years from Earth in the Large Magellanic Cloud. It was first observed on Earth in February 1987, and its brightness peaked in May of that year. It was the first supernova that could be seen with the naked eye since Kepler's Supernova was observed in 1604.About two hours prior to the first visible-light observation of SN 1987A, three observatories around the world detected a burst of neutrinos lasting only a few seconds. The two different types of observations were linked to the same supernova event, and provided important evidence to inform the theory of how core-collapse supernovae take place. This theory included the expectation that this type of supernova would form a neutron star or a black hole. Astronomers have searched for evidence for one or the other of these compact objects at the center of the expanding remnant material ever since.Indirect evidence for the presence of a neutron star at the center of the remnant has been found in the past few years, and observations of much older supernova remnants –such as the Crab Nebula – confirm that neutron stars are found in many supernova remnants. However, no direct evidence of a neutron star in the aftermath of SN 1987A (or any other such recent supernova explosion) had been observed, until now.The James Webb Space Telescope has observed the best evidence yet for emission from a neutron star at the site of a well-known and recently-observed supernova known as SN 1987A. At left is a NIRCam (Near-Infrared Camera) image released in 2023. The image at top right shows light from singly ionized argon (Argon II) captured by the Medium Resolution Spectrograph (MRS) mode of MIRI (Mid-Infrared Instrument). The image at bottom right shows light from multiply ionized argon captured by the NIRSpec (Near-Infrared Spectrograph). Both instruments show a strong signal from the center of the supernova remnant. This indicated to the science team that there is a source of high-energy radiation there, most likely a neutron star.NASA, ESA, CSA, STScI, C. Fransson (Stockholm University), M. Matsuura (Cardiff University), M. J. Barlow (University College London), P. J. Kavanagh (Maynooth University), J. Larsson (KTH Royal Institute of Technology)Claes Fransson of Stockholm University, and the lead author on this study, explained: “From theoretical models of SN 1987A, the 10-second burst of neutrinos observed just before the supernova implied that a neutron star or black hole was formed in the explosion. But we have not observed any compelling signature of such a newborn object from any supernova explosion. With this observatory, we have now found direct evidence for emission triggered by the newborn compact object, most likely a neutron star.”Webb's Observations of SN 1987AWebb began science observations in July 2022, and the Webb observations behind this work were taken on July 16, making the SN 1987A remnant one of the first objects observed by Webb. The team used the Medium Resolution Spectrograph (MRS) mode of Webb's MIRI (Mid-Infrared Instrument), which members of the same team helped to develop. The MRS is a type of instrument known as an Integral Field Unit (IFU).IFUs are able to image an object and take a spectrum of it at the same time. An IFU forms a spectrum at each pixel, allowing observers to see spectroscopic differences across the object. Analysis of the Doppler shift of each spectrum also permits the evaluation of the velocity at each position.Spectral analysis of the results showed a strong signal due to ionized argon from the center of the ejected material that surrounds the original site of SN 1987A. Subsequent observations using Webb's NIRSpec (Near-Infrared Spectrograph) IFU at shorter wavelengths found even more heavily ionized chemical elements, particularly five times ionized argon (meaning argon atoms that have lost five of their 18 electrons). Such ions require highly energetic photons to form, and those photons have to come from somewhere.“To create these ions that we observed in the ejecta, it was clear that there had to be a source of high-energy radiation in the center of the SN 1987A remnant,” Fransson said. “In the paper we discuss different possibilities, finding that only a few scenarios are likely, and all of these involve a newly born neutron star.”More observations are planned this year, with Webb and ground-based telescopes. The research team hopes ongoing study will provide more clarity about exactly what is happening in the heart of the SN 1987A remnant. These observations will hopefully stimulate the development of more detailed models, ultimately enabling astronomers to better understand not just SN 1987A, but all core-collapse supernovae.These findings were published in the journal Science.The James Webb Space Telescope is the world's premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

In this episode, we are delving into the science of supernovas. The James Webb Space Telescope has revealed the clearest ever view of the stunning Cassiopeia A supernova, complete with a weird feature called 'the green monster'. Professor Dan Milisavljevic, an astronomer at Purdue University, tells us all about his research into this space-based beauty. Professor Tamara Davis from the University of Queensland has been turning her eye to far more distant supernovas, and explains how they have given us new insight into the Universe's expansion. Moving on to human history, William Barrie from the University of Cambridge tells us about a new study that explores the reason for high levels of multiple sclerosis in northern Europe. And going further back in time, researcher Ethan Mooney has studied a sample of fossilised skin, which may be the oldest ever discovered.

What happens to one sun of a binary pair if the other goes supernova? Can we mitigate the greenhouse effect? How big should a telescope be? For our Season 2 finale, we're answering fan questions from YouTube, Instagram, and Facebook. To bring those questions to life, Dr. Charles Liu and co-host Allen Liu welcome two members of the LIUniverse social media team, “Vinyl Benjy” Schoenfeld, our TikTok manager, and Stacey Severn, our Social Media Director. As always, though, we start off with the season's final joyfully cool cosmic thing, the most recent image of Uranus by the James Webb Space Telescope. Taken using the JWST's infrared imaging capabilities, rather than visible light, this incredibly beautiful photo of Uranus clearly shows its 7 spectacular rings and 14 moons. Now, on to your questions! First, Stacey reads a question from YouTube fan Darker Void Scientist, who asks, “Wouldn't some violently spinning galaxies produce strong magnetic fields that act as a barrier to some spectrum of traveling waves?” To answer, Charles gets to discuss the Zeeman Effect and the Parker Instability. He explains that entire galaxies can't spin fast enough, but that violent spinning does occur and produce magnetic fields closer to the supermassive black holes in the center of those galaxies. Benjy reads our next question, from YouTube fan Mark Caesar 4443: “When stars go very near black holes and get sling-shotted around them, what would we see of them in terms of time dilation? Surely we would see them slow down as they approach the black hole, of course, that is assuming we can actually observe them.” Chuck dives into what we would be able to perceive at all, from our perspective, and why we would see color shifts but not necessarily the impact of time dilation that the star itself would experience. Allen tackles the next question, from Randy Starnes on Facebook, who wants to know whether we could take a rechargeable battery and use it to power a plasma rocket. Our co-host explains that while rechargeable batteries wouldn't generate enough energy for a plasma engine, lithium-ion rechargeable batteries are used by Rocket Lab for the electric pumps on their reusable Electron rockets. Stacey next asks another question from YouTube, from @sbkarajan: “How do NASA or anyone measure distance from the planet to the Sun? I heard for Earth they measure the distance to Mars or Venus transit using Keppler's Third Law. Is it the only way?” Chuck explains that when humanity was still stuck on Earth, that was the only way. But since we have more tactics at our disposal, from satellites to radar signals, to do far more accurate measurements, even at vast distances. Next up, @frankwestphal8532 from YouTube: “What would happen to the other star in a supermassive star binary system if one of the stars ‘supernova-ed' before the other?” It turns out that happens all of the time... and none of the outcomes tend to be good for the other star. But Frank's not done, and his follow up question about the early universe, binary-system supernovae, and the creation of supermassive black holes is a bit of a chin-scratcher for Chuck! Stacey's next question comes via Instagram from our friends CJ Dearinger and Dr. Mounce on the “All Things – Unexplained” podcast: “When will astrophysics encounter/present undeniable proof of a new life form?” Predictions, obstacles, and discussion of alien cryptids ensue. In another Instagram question, Ben Jordans asks, “How do you perceive the current efforts to mitigate the greenhouse effect? Are you of the opinion that we will succeed in mastering this problem, and if so, how?” Chuck explains the greenhouse effect, on Earth as well as on Venus and Mars, and the difference between the effect itself and human involvement in it. He and Allen disagree as to how long it might take to redress the problem, while Stacey and Benjy jump in with their more pessimistic concerns about climate change, extreme weather, and the future. Benjy gets the last question, from @emiliotorres2718 on YouTube: “How do we go about deciding how big we want a telescope to be? Is it simply the bigger the telescope we make, the farther we'll be able to see into the universe?” Chuck says the simple answer is yes, but the actual answer is more complicated. To hear it, you'll have to watch or listen in to the final episode of Season 2 of The LIUniverse! We hope you enjoy The LIUniverse, and, if so, please support us on Patreon. We'll return for Season 3 in 2024.

Webb's study of the second-brightest gamma-ray burst ever seen reveals tellurium.A team of scientists has used multiple space and ground-based telescopes, including NASA's James Webb Space Telescope, NASA's Fermi Gamma-ray Space Telescope, and NASA's Neil Gehrels Swift Observatory, to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.Image: Gamma-Ray Burst 230307AThis image from NASA's James Webb Space Telescope NIRCam (Near-Infrared Camera) instrument highlights Gamma-Ray Burst (GRB) 230307A and its associated kilonova, as well as its former home galaxy, among their local environment of other galaxies and foreground stars. The GRB likely was powered by the merger of two neutron stars. The neutron stars were kicked out of their home galaxy and traveled the distance of about 120,000 light-years, approximately the diameter of the Milky Way galaxy, before finally merging several hundred million years later.Image: NASA, ESA, CSA, STScI, A. Levan (Radboud University and University of Warwick).Other elements near tellurium on the periodic table – like iodine, which is needed for much of life on Earth – are also likely to be present among the kilonova's ejected material. A kilonova is an explosion produced by a neutron star merging with either a black hole or with another neutron star.“Just over 150 years since Dmitri Mendeleev wrote down the periodic table of elements, we are now finally in the position to start filling in those last blanks of understanding where everything was made, thanks to Webb,” said Andrew Levan of Radboud University in the Netherlands and the University of Warwick in the UK, lead author of the study.While neutron star mergers have long been theorized as being the ideal “pressure cookers” to create some of the rarer elements substantially heavier than iron, astronomers have previously encountered a few obstacles in obtaining solid evidence.Long Gamma-Ray BurstKilonovae are extremely rare, making it difficult to observe these events. Short gamma-ray bursts (GRBs), traditionally thought to be those that last less than two seconds, can be byproducts of these infrequent merger episodes. (In contrast, long gamma-ray bursts may last several minutes and are usually associated with the explosive death of a massive star.)The case of GRB 230307A is particularly remarkable. First detected by Fermi in March, it is the second brightest GRB observed in over 50 years of observations, about 1,000 times brighter than a typical gamma-ray burst that Fermi observes. It also lasted for 200 seconds, placing it firmly in the category of long duration gamma-ray bursts, despite its different origin.“This burst is way into the long category. It's not near the border. But it seems to be coming from a merging neutron star,” added Eric Burns, a co-author of the paper and member of the Fermi team at Louisiana State University.Opportunity: Telescope CollaborationThe collaboration of many telescopes on the ground and in space allowed scientists to piece together a wealth of information about this event as soon as the burst was first detected. It is an example of how satellites and telescopes work together to witness changes in the universe as they unfold. After the first detection, an intensive series of observations from the ground and from space, including with Swift, swung into action to pinpoint the source on the sky and track how its brightness changed. These observations in the gamma-ray, X-ray, optical, infrared, and radio showed that the optical/infrared counterpart was faint, evolved quickly, and became very red – the hallmarks of a kilonova.“This type of explosion is very rapid, with the material in the explosion also expanding swiftly,” said Om Sharan Salafia, a co-author of the study at the INAF – Brera Astronomical Observatory in Italy. “As the whole cloud expands, the material cools off quickly and the peak of its light becomes visible in infrared, and becomes redder on timescales of days to weeks.”Image: Killanova – Webb vs ModelThis graphic presentation compares the spectral data of GRB 230307A's kilonova as observed by NASA's James Webb Space Telescope and a kilonova model. Both show a distinct peak in the region of the spectrum associated with tellurium, with the area shaded in red. The detection of tellurium, which is rarer than platinum on Earth, marks Webb's first direct look at an individual heavy element from a kilonova.Illustration: NASA, ESA, CSA, Joseph Olmsted (STScI).At later times it would have been impossible to study this kilonova from the ground, but these were the perfect conditions for Webb's NIRCam (Near-Infrared Camera) and NIRSpec (Near-Infrared Spectrograph) instruments to observe this tumultuous environment. The spectrum has broad lines that show the material is ejected at high speeds, but one feature is clear: light emitted by tellurium, an element rarer than platinum on Earth.The highly sensitive infrared capabilities of Webb helped scientists identify the home address of the two neutron stars that created the kilonova: a spiral galaxy about 120,000 light-years away from the site of the merger.Prior to their venture, they were once two normal massive stars that formed a binary system in their home spiral galaxy. Since the duo was gravitationally bound, both stars were launched together on two separate occasions: when one among the pair exploded as a supernova and became a neutron star, and when the other star followed suit.In this case, the neutron stars remained as a binary system despite two explosive jolts and were kicked out of their home galaxy. The pair traveled approximately the equivalent of the Milky Way galaxy's diameter before merging several hundred million years later.Scientists expect to find even more kilonovae in the future due to the increasing opportunities to have space and ground-based telescopes work in complementary ways to study changes in the universe. For example, while Webb can peer deeper into space than ever before, the remarkable field of view of NASA's upcoming Nancy Grace Roman Space Telescope will enable astronomers to scout where and how frequently these explosions occur.“Webb provides a phenomenal boost and may find even heavier elements,” said Ben Gompertz, a co-author of the study at the University of Birmingham in the UK. “As we get more frequent observations, the models will improve and the spectrum may evolve more in time. Webb has certainly opened the door to do a lot more, and its abilities will be completely transformative for our understanding of the universe.”These findings have been published in the journal Nature.The James Webb Space Telescope is the world's premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.This show is part of the Spreaker Prime Network, if you are interested in advertising on this podcast, contact us at https://www.spreaker.com/show/5953955/advertisement

How did our solar system get here? How did the Earth form? How commonly does that happen elsewhere, and how often do the conditions necessary for life come about? To find out, Dr. Charles Liu and co-host Allen Liu welcome Dr. Tom Rice, Astronomer-Educator and AAS staffer, who studies star and planet formations, how solar systems come together out of the “stuff that's out there floating in our galaxy like gas and dust.” As always, though, we start off with the day's joyfully cool cosmic thing, the discovery of “baby” brown dwarf TWA 27B that we are watching grow thanks to the James Webb Space Telescope. Tom explains that a brown dwarf is not massive enough to ignite the hydrogen in their cores and turn into a star, but is 13 times more massive than gas giant planets like Jupiter. Allen asks Tom about temporal scales and “baby objects” – Tom defines objects as “young” that are still accreting mass, and tend to be in the range of 1-10 million years old. And as for calling brown dwarfs failed stars, well, you'll just have to watch or listen for Tom's opinion about that very controversial subject. Then it's time for a student question, from Alianna, who asks, “Can a star turn into a planet?” To answer, Tom uses a different distinction between stars, brown dwarfs, and planets: how they form. He explains the development from a region of gas and dust that gets dense and then collapses under its own weight, into a circumstellar disc accreting matter with an object at its center, growing either into a star, or, if it's too low a mass to ignite, a brown dwarf. A planet forms in a different process, not in the center of the circumstellar disc (aka, the protoplanetary disc) but out of the “stuff” in the disc, at the same time the star is forming. So, Tom says, the answer to the question is “probably no.” Tom and Chuck then discusss a couple of hypothetical situations that could possibly reduce a star to the mass of the planet. They also compare the atmosphere composition of planets and stars. In the case of Jupiter, the composition is very similar to the sun, but the temperature is much cooler, so there are some molecules that form in its atmosphere that would remain in their atomic states in the Sun. Then we enter the goldilocks zone to discuss what it takes to create a planet that can sustain life, like on Earth. Tom runs down the “must haves” for life, and then turns to the search for earthlike exoplanets using the Kepler and TESS space telescopes. You'll learn about the transit method of exoplanet detection and what we can learn from it, including size and orbital frequency (which helps determine distance from the sun and therefore habitable temperatures). Next we hear about Tom's work on the staff of the American Astronomical Society. His focus: figuring out how channel the energy of society members to improve astronomy education at all levels. If you have a suggestion for Tom, you can find him on Twitter (X) @tomr_stargazer or email him at tom.rice@aas.org. This being The LIUniverse, Chuck Tom and Allen end up the episode talking about video games, from Super Planet Crasher to Space Engine 2 and Universe Sandbox to the Zelda game, Tears of the Kingdom which has a ton of physics stuff in it– yes, you read that right! By the way, if Tom looks familiar to you, that might be because he was in our video Chuck recorded at the AAS meeting in Pasadena last year where he showed us his fluency with American Sign Language. Tom is a CODA (Child of Deaf Adults)  and ASL and his signing identity is an important part of his heritage. He lives in Washington, DC, near Gallaudet University, the nation's only entirely signing university, where Tom works with the Astronomy Club. He's also working with The National Technical Institute for the Deaf at Rochester Institute of Technology on activities relating to the upcoming total solar eclipse on April 8, 2024 that will pass directly overhead. If you want to see Tom sign a few astronomic terms including the one for “the planet we live on...the most important place we can know,” watch our video at https://www.instagram.com/reel/Ce4kc96gOT5/.

Mack Bradly, a local space writer, joins Mark Reardon to discuss what lies ahead for NASA, and NASA's plan to one-up the James Webb Space Telescope! © 2023 KFTK (Audacy). All rights reserved. | (Photo by NASA, ESA, CSA, and STScI via Getty Images)

NASA's James Webb Space Telescope has produced amazing images in its first 5 months, but amazing science as well. Roland hears from one of the leading astronomers on the JWST programme, Dr Heidi Hammel, as well as other experts on what they are already learning about the first galaxies in the Universe, the birth places of stars, the strange behaviour of some other stars, and the first view of Neptune's rings in over 30 years. Over the past 12 months, CrowdScience has travelled the world, from arctic glacierscapes to equatorial deserts, to answer listeners' science queries. Sometimes, the team come across tales that don't quite fit with the quest in hand, but still draw a laugh, or a gasp. In this show, Marnie Chesterton revisits those stories, with members of the CrowdScience crew. Alex the Parrot was a smart bird, with an impressive vocabulary and the ability to count and do basic maths. He was also intimidating and mean to a younger parrot, Griffin, who didn't have the same grasp of the English language. Scientist Irene Pepperberg shares the consequence of this work-place bullying.  Take a tour of the disaster room at ICPAC, the IGAD Climate Prediction and Applications Centre (ICPAC) based in Nairobi, Kenya. It's a new building where scientists keep watch for weird new weather and passes that information to 11 East African countries. Viola Otieno is an Earth Observation (EO) Expert and she explained how they track everything from cyclones to clouds of desert locust. Malcolm MacCallum is curator of the Anatomical Museum at Edinburgh University in Scotland, which holds a collection of death masks and skull casts used by the Edinburgh Phrenological Society. Phrenology was a pseudoscience, popular in the 1820s, where individuals attempted to elucidate peoples' proclivities and personalities by the shape of their heads. We see what the phrenologists had to say about Sir Isaac Newton and the “worst pirate” John Tardy. While recording on Greenland's icesheet, the CrowdScience team were told by Professor Jason Box about “party ice.” 40,000 year old glacial ice is a superior garnish for your cocktail than normal freezer ice, apparently.

Odkar je poleti začel z resnim znanstvenim delom, Vesoljski teleskop Jamesa Webba navdušuje z bogastvom podatkov in podrobnimi ter tudi čudovitimi fotografijami. Več kot očitno je, da prinaša res številna nova spoznanja o vesolju, nove uvide. Med svežimi odkritji je tudi galaksija s svetlikajočimi se najstarejšimi zvezdnimi kopicami v vesolju, ki jo je odkrila mednarodna skupina raziskovalcev, pri kateri sodeluje tudi naša astrofizičarka prof. dr. Maruša Bradač s Fakultete za matematiko in fiziko Univerze v Ljubljani. Opis slike: Raziskovalci so preučili galaksijo Sparkler v Webbovem prvem globokem polju in s pomočjo teleskopa JWST za pet svetlikajočih se objektov okrog galaksije ugotovili, da so kroglaste kopice.

On this week's show: The first images from the James Webb Space Telescope hint at the science to come, and disentangling the itch-scratch cycle After years of delays, the James Webb Space Telescope launched at the end of December 2021. Now, NASA has released a few of the first full-color images captured by the instrument's enormous mirror. Staff Writer Daniel Clery joins host Sarah Crespi to discuss these first images and what they mean for the future of science from Webb. Next on the podcast, Jing Feng, principal investigator at the Center for Neurological and Psychiatric Research and Drug Discovery at the Chinese Academy of Sciences's Shanghai Institute of Materia Medica, discusses his Science Translational Medicine paper on why scratching sometimes triggers itching. It turns out, in cases of chronic itch there can be a miswiring in the skin. Cells that normally detect light touch instead connect with nerve fibers that convey a sensation of itchiness. This miswiring means light touches (such as scratching) are felt as itchiness—contributing to a vicious itch-scratch cycle. Also this week, in a sponsored segment from Science and the AAAS Custom Publishing Office, Sean Sanders, director and senior editor for the Custom Publishing Office, interviews Paul Bastard, chief resident in the department of pediatrics at the Necker Hospital for Sick Children in Paris and a researcher at the Imagine Institute in Paris and Rockefeller University. They talk about his work to shed light on susceptibility to COVID-19, which recently won him the Michelson Philanthropies & Science Prize for Immunology.

A sparkling landscape of baby stars. A foamy blue and orange view of a dying star. Five galaxies in a cosmic dance. The splendours of the universe glowed in a new batch of images released from Nasa's powerful new telescope.The unveiling from the $10 billion James Webb Space Telescope began on Monday at the White House with a sneak peek of the first shot — a jumble of distant galaxies that reached deeper into the cosmos than humanity has ever seen. A star-forming region in the Carina Nebula captured in infrared light by the Near-Infrared Camera and Mid-Infrared Instrument. Image / Nasa ESA, CSA, STScI via APYesterday's releases showed parts of the universe seen by other telescopes. But Webb's sheer power, distance from Earth and use of the infrared spectrum showed them in a new light."It's the beauty but also the story," Nasa senior Webb scientist John Mather, a Nobel laureate, said after the reveal. "It's the story of where did we come from." An image of the Southern Ring Nebula being displayed at the Nasa press conference. Photo / Marcio Jose Sanchez, APAnd, he said, the more he looked at the images, the more he became convinced that life exists elsewhere in those thousands of stars and hundreds of galaxies.With Webb, scientists hope to glimpse light from the first stars and galaxies that formed 13.7 billion years ago, just 100 million years from the universe-creating Big Bang. The telescope also will scan the atmospheres of alien worlds for possible signs of life."Every image is a new discovery and each will give humanity a view of the humanity that we've never seen before," Nasa administrator Bill Nelson said, rhapsodising over images showing "the formation of stars, devouring black holes".Webb's use of the infrared light spectrum allows the telescope to see through the cosmic dust and see faraway light from the corners of the universe, he said.

Webb is considered the successor to the highly successful, but ageing Hubble Space Telescope.Shown Tuesday:Southern Ring nebula, which is sometimes called "eight-burst". Images show a dying star with a foamy edge of escaping gas. It's about 2500 light years away.

One view was a stunning landscape of orange cliffs.Stephan's Quintet, five galaxies in a cosmic dance that was discovered 145 years ago in the constellation Pegasus. It includes a black hole that scientists said showed material "swallowed by this sort of cosmic monster". Webb "has just given us a new, unprecedented 290 million-year-old view of what this Quintet is up to", said Cornell University astronomer Lisa Kaltenegger, who wasn't part of the Webb team.A giant planet called Wasp-96b. It's about the size of Saturn and is 1150 light years away. A gas planet, it's not a candidate for life but a key target for astronomers. Instead of an image, the telescope used its infrared detectors to look at the chemical composition of the planet's atmosphere. It showed water vapour in the super-hot planet's atmosphere and even found the chemical spectrum of neon.The images were released at an event at Nasa's Goddard Space Centre that included cheerleaders with pompoms the colour of the telescope's golden mirrors."It moves you. This is so so beautiful," Thomas Zurbuchen, chief of Nasa's science missions, said afterwards. "Nature is beautiful.

Telescopes have been fundamental in our understanding of our place in the universe. And when you think about images that have shaped our modern view of space, you probably think about Hubble. But just this year, the JWST or James Web Space Telescope, was launch. JWST will go far beyond what Hubble has discovered. And did you know Python is used extensively in the whole data pipeline of JWST? We have two great guests here to tell us about it: Megan Sosey and Mike Swam.

Gerade dachten wir, das All ein wenig zu verstehen - und nun stehen wir wieder am Anfang. Während Forscher*innen bis jetzt damit rechneten, dass unsere Heimatgalaxie erst in Milliarden von Jahren auf die Andromedagalaxie treffen wird, sieht das heute ganz anders aus. Schon in diesem Moment berühren sich die gigantischen Halos der Galaxien. Was das bedeutet, ist noch nicht ganz greifbar. Doch das Wichtigste zuerst: Forschende sind überzeugt, dass unser Sonnensystem sicher ist. Nicht ausgeschlossen ist jedoch die Möglichkeit, dass die aufeinander prallenden Kräfte der äußersten Ringe einen Asteroidenhagel ins Innere senden. Was wird entstehen? Mit was sollten wir rechnen - apokalyptisches Asteroiden-Bombardement - oder bloß ein paar neue Sterne am Himmel? Das und mehr im heutigen Podcast von Clixoom Science und Future.

Denne gang zoomer vi ind på verdens største rumteleskop, James Webb Space Telescope, der efter planen skal opsendes i slutningen af 2021, og dermed indvarsle begyndelsen på en helt ny æra indenfor rumteleskoper. JWST, som det hedder mellem venner, bliver udstyret med følsomme instrumenter til blandt andet at observere i det infrarøde spektrum. Af samme årsag placeres JWST langt fra Jorden og skal beskyttes af et stort solskjold, fordi instrumenterne skal være kølet ned til under -220 grader Celsius for at fungere optimalt. Vi har talt med Klaus Pontoppidan som er James Webb Space Telescope Project Scientist ved Space Telescope Science Institute i Baltimore i USA. Vi skal dog også have et par aktuelle nyheder, blandt andet om et nyt rumlokum, og selvfølgelig lidt baggrund om JWST. God fornøjelse!

Presented by Dr Pamela Gay on 13th September 2013.In order to handle the onslaught of data coming from space and ground-based telescopes, many astronomers are turning to the public for aid. The team behind the new CosmoQuest virtual research centre is building a first of its kind research community for professional and citizen scientists to work together on advancing our understanding of the universe; a community of people who are participating in doing science, and in learning about this cosmos we share. Working with NASA's Dawn, LRO, MESSENGER, and STScI teams, this facility is developing citizen science projects that accomplish needed tasks for mission science teams. It also provides a rich educational context through online classes, virtual star parties, and community collaboration areas. This talk will overview the history of citizen discovery and discuss CosmoQuest and how you can help discover our universe.

Ok, this is what a lot of you have been waiting for, and with very good reason! Get your thinking hats on, turn off your phones, get a nice cup of tea, clear your schedule, and bring forth your scientific aspect. In this podcast episode, B. Alan Wallace, Ph.D., will be delving into topics such as the nature of information, mind and matter as a derivative of information, the placebo effect, its connection to the flow of experience/information in relation to human existence, and oh, why not: quantum cosmology (just to name a few).This is the main episode, and I will add a second episode with two semi-short followups from the next day.I will not do any paraphrasing of information here, but I will try to list a few of the topics that come up in each part. Keep in mind that I will only list the main topics (not the topics in between topics), and perhaps not even all of them. This superanswer stems out of a question from Noah, who asked Alan to clarify a point from a previous day in which he mentioned that the information stored in his computer was “above and beyond” just a complex configuration of chemicals and electricity. The question asks for an explanation of the term “information” and how it can be causally efficacious. This part starts with a synopsis on the elegant Buddhist hypothesis of human existence as a flow of experience and information, before the division of mind and body. Then, we go into a discussion of the nature of information, followed by a well-supported rejection of assuming the categorical error “subjective experience arises from the brain” which predominates in modern science, leading to the so called “hard problem of consciousness,” which Alan then briefly discusses. This is followed by a very sharp analysis of the placebo effect in relation to human existence as a flow of experience and information, and why 50 years of modern science have failed to explain how it works. As we approach the end of the podcast, Alan shows how much of the modern scientific research on the mind has been hindered because of the fact that if you ask physical questions, you are going to get physical answers. Observing with physical instruments will lead to physical phenomena. To end majestically, Alan uses an example from Stephen Hawkins in order to relate this to the whole cosmos. Stephen Hawkins said (about the big bang and the current cosmological theory), something along the lines of “That story is based on the type of questions you were posing, and all of the questions you were posing were physical questions based on physical measurements.” A macrocosmic projection of the last 400 years in the development of science.I will stop my attempt at paraphrasing here, in order to let you listen to the end of this last part without my measly commentary. I will just say (you know me by now) that it was the most mind-blowing of all of the information we have received thus far.The image used on the web and on the podcast file is the HUBBLE ULTRA DEEP FIELD. , the deepest portrait of the visible universe ever achieved by humankind.Credit: NASA, ESA, S.

This is a short followup (I promise! It’s actually less than 15 minutes) clearing up some points from the previous episode. I took two fragments from the next day and mashed them together for this podcast. It is absolutely necessary to listen to Part 1 before listening to this. In this first fragment B. Alan Wallace briefly returns to the topic of information flow, meaning-to-meaning communication (instead of achieving means through chemicals and brain correlates), and relates this to the placebo effect, specifically to how it is a blatant example of the mind’s capacity to heal itself and heal the body although modern science prefers to wrap itself up in tight conundrums and knots rather than accept this fact.Then I cut to another fragment from the afternoon session in which B. Alan Wallace clears up some more points about the stream of name and flow and the mind-body problem. He details the hypothesis of the flow of consciousness (information), energy, and space as existence before the mind and body duality. In less than 5 minutes!And to end this two-part podcast with an encouraging, defiant, educated, and exciting bang, Alan goes back to the history of Galileo. He shows how Galileo achieved authority in physics and ended up taking a “piece of the pie” from the church, simply because he really observed phenomena directly and this gave him the authority to be right, rather than believe people who make claims without really investigating the phenomenon which they claim absolute authority of.This is what needs to happen in the mind sciences. As was said in Part 1, observing through physical means and asking physical questions will lead to physical answers. The mind is obviously not physical. This means that the authority over the science of the mind should be not in the hands of scientific materialists, it should be in the hands of professional, highly trained contemplatives who have been studying this field for millennia. Just as Galileo claimed authority in the physical sciences from the Catholic Church, so must contemplatives claim authority from the “Church Scientific” in regards to the domain of the mind. This scientific materialism is extending its domain way beyond what they know about, and reducing everything to biological mechanisms simply won’t provide answers. So, let them contribute with their immensely valuable biological information about the brain, and let the real experts of the mind come in and contribute with their millennia-old knowledge of the mind. Galileo did it, now it’s our turn to do it if we really want to advance scientifically in the study of the mind. Biology won’t cut it anymore.The image used on the web and on the podcast file is the HUBBLE ULTRA DEEP FIELD. , the deepest portrait of the visible universe ever achieved by humankind.Credit: NASA, ESA, S.
