Real Life: Steven is sick or dead, we don't remember, so Ben and Devon take over the show. Devon is traveling for the holidays so needs to bill as much as possible at work. Devon explains what it's like to be an independent contractor. Ben's work is a little less reliable. Snoop Dogg records a holiday message for Ben's parent, parent, parent company. Snoop Dogg is somehow still as famous as ever. Future or Now: This Week in Space Astrophysicists capture astonishing images of gamma-ray flare from supermassive black hole M87. The jet is tens of millions of times larger than the black hole's event horizon. The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the galaxy's center. An international research team has now observed a teraelectronvolt gamma-ray flare seven orders of magnitude -- tens of millions of times -- larger than the event horizon, or surface of the black hole itself. A flare of this intensity -- which has not been observed in over a decade -- can offer crucial insights into how particles, such as electrons and positrons, are accelerated in the extreme environments near black holes. https://www.sciencedaily.com/releases/2024/12/241213140634.htm https://en.wikipedia.org/wiki/Messier_87 Black holes and why they look like that: https://youtu.be/zUyH3XhpLTo?si=7drAgoVloX9hytmo New Technology Could Keep Communications Going During Disasters RNZ (12/6) News from New Zealand: “The 'mesh node' is a small black walkie-talkie sized box that connects to a cellphone through Bluetooth. It then connects to a network of solar powered nodes across the region, which allows users to send short text messages, even when all other communications are down. It has been tailor-made by Tai Rāwhiti Civil Defence, and emergency manager Ben Green said it is "a cost-effective solution for reliable communications in a disaster.” https://www.rnz.co.nz/news/national/535819/new-technology-could-keep-communications-going-during-disasters Book Club: Next week book club: WHERE RABBITS COME FROM, a French animated short film that's being shopped around for awards this season.

Earthquakes create a spark in quartz that can form massive gold nuggetsScientists have figured out why up to 75 per cent of all the gold ever mined forms inside quartz in areas with a long history of earthquakes. Chris Voisey, a Canadian geologist at Monash University in Australia, said he was trying to solve how gold arose inside quartz. In his study in the journal Nature Geoscience, he found that earthquake stress on quartz crystals generates an electrical voltage that causes dissolved gold to precipitate into a solid that can grow into the largest nuggets ever found.Ice Age Teens went through puberty just like today's kidsA new analysis of the bones of teenagers from 25,000 years ago shows they experienced puberty in much the same way as teens today. An international team of researchers including Paleolithic archaeologist April Nowell analyzed the bones of 13 teens found across Europe, and by looking at particular markers in the bones, they were able to see which stage of puberty the teens were in when they died. The researchers could not only infer things like whether their voices were breaking, but by doing muscle analysis, they found that the teens were healthy and active, and likely involved in hunting and fishing. The research was published in the Journal of Human Evolution.Grey sharks are abandoning warming coral reefs in the Indian OceanThe grey shark in the Indian Ocean uses beautiful coral reefs as a home base, returning each day after a night of fishing. But lately the sharks have been staying away for longer periods of time, up to 16 months. Dr. Michael Willamson, a research scientist at the Zoological Society of London, found that climate change is stressing the reefs. The sharks seek out cooler but potentially more dangerous waters. Venturing away from the protected reef area leaves them more vulnerable to illegal shark fishing. The paper was published in the journal Communications BiologyA cosmic collision 9 billion years ago could be the origin of he supermassive black hole at the centre of our galaxy Using data from The Event Horizon Telescope, Dr. Yihan Wang worked with Dr. Bing Zhang at the Nevada Institute of Astrophysics to study the origins of the supermassive black hole at the centre of our galaxy. From the EHT image of the Sagittarius A* Dr. Wang and his team made an accretion model and saw that it spins very fast and that the spinning is misaligned. They believe it may have been made by merging with another supermassive black hole. about 9 billion years ago. Their paper was published in Nature Astronomy.Astronaut Roberta Bondar gives a bird's eye view of migration 32 years after she flew on the space shuttle, Roberta Bondar is still showing us what the Earth looks like from space — and from closer to the ground. Dr. Bondar trained as a wildlife photographer after her astronaut career. For a new project collected photos from space, from airplanes and helicopters, and from the ground, to bring a new perspective on the migration of two important bird species, the threatened lesser Flamingo and the endangered Whooping Crane. The book is called Space for Birds: Patterns and Parallels of Beauty and Flight.

Astronomy Daily - The Podcast: 31 August 2024Welcome to Astronomy Daily, your source for the latest in space exploration and Astronomy. I'm your host, Anna. Today, we've got some fascinating stories lined up for you. From SpaceX receiving the green light to fly their Falcon 9 rocket again after a recent mishap, to NASA's strategic crew adjustments on their SpaceX flights, there's a lot to cover. We're also diving into groundbreaking advancements with the Event Horizon Telescope that promise to reveal clearer images of black holes than ever before. And we'll take a closer look at how New Zealand's rapidly growing space sector is grappling with sustainability challenges. So let's dive right into the latest updates and breakthroughs.Highlights:- SpaceX Falcon 9 Cleared for Launch: The Federal Aviation Administration (FAA) has given SpaceX the green light to restart its Falcon 9 launches following an investigation into a recent mishap. Despite a first stage booster tipping over and exploding while attempting to land on a drone ship, the mission successfully delivered 21 Starlink Internet satellites into orbit. This incident marked an end to a streak lasting over three years of successful booster landings. The FAA has allowed the Falcon 9 to return to flight operations, demonstrating SpaceX's resilience and adaptability.- NASA's Crew Dragon Flight Adjustments: NASA has announced changes to its upcoming SpaceX Crew Dragon flight, reassigning astronauts to make room for the crew from Boeing's Starliner capsule. This decision ensures seamless coordination with Roscosmos and maintains collaborative efforts on the International Space Station (ISS). The Crew-9 flight, now set for September 24, will be captained by Nick Haig, with Russian cosmonaut Alexander Gorbanov joining as the mission specialist.- Event Horizon Telescope Advancements: The Event Horizon Telescope (EHT) team has made significant strides in improving the resolution of black hole images. Collaborating with the Atacama Large Millimeter/submillimeter Array (ALMA) and other facilities, the EHT team achieved an astonishing level of observational detail. These advancements promise to reveal more detailed properties around black holes, potentially uncovering both predicted and unexpected phenomena.- New Zealand's Aerospace Sector and Sustainability: New Zealand's aerospace sector is experiencing rapid growth with ambitious goals for the global space industry. However, this growth brings pressing sustainability issues to light. Balancing economic expansion with sustainable practices is crucial as the global community becomes more aware of space debris and other environmental concerns. New Zealand's aerospace strategy includes a bilateral agreement with the United States and policies on space debris removal, but critics argue that more proactive measures are needed.For more space news, be sure to visit our website at astronomydaily.io.

Previously the only way to image black holes was with the Event Horizon Telescope, a combination of many radio telescopes across the globe. It is complicated and time-consuming. But with Vera Rubin going online soon, there might be a simpler way to observe black holes with a single telescope using a really clever method.

Schwarze Löcher üben seit jeher eine große Faszination auf Menschen aus. Ein Grund dafür ist, dass es lange Zeit als unmöglich galt, sie fotografisch abzubilden, und daher nicht bekannt war, wie sie überhaupt aussehen. Im Jahr 2019 gelang Dr. Luciano Rezzolla, einem italienischen Astrophysiker und Professor an der Goethe-Universität Frankfurt, mit der Forschungskollaboration des Event Horizon Telescope ein bahnbrechender Durchbruch: Er gehörte zu den Ersten, denen es gelang, fotografische Aufnahmen eines supermassiven Schwarzen Lochs zu erstellen. Rezzollas Forschungsschwerpunkte sind astrophysikalische kompakte Objekte wie Schwarze Löcher und Neutronensterne, die er mithilfe von Supercomputern untersucht. Wie kann ein Schwarzes Loch fotografisch abgebildet werden? Was bedeuten sie für die Wissenschaft? Was sind Neutronensterne und was geschieht, wenn sie kollidieren? Diese und weitere Fragen diskutieren wir in dieser Folge von "Hessen schafft Wissen" mit Dr. Luciano Rezzolla. Viel Spaß dabei!

Vesolje je polno vznemirljivih ugank; samo v naši galaksiji bi, na primer, utegnilo biti okoli 100 milijonov črnih lukenj. Problem je seveda v tem, da jih neposredno ne moremo videti. Izdaja jih predvsem vpliv, ki ga imajo na zvezde, ki so dovolj blizu, da se znajdejo v njihovem gravitacijskem objemu, iz katerega, kot vemo, ni moč pobegniti. A črne luknje še zdaleč niso edini fenomen v vesolju, katerega obstoj lahko zaznamo, izmerimo in izračunamo, ne da bi pri tem imeli kakšne zelo jasne predstave, za kaj pravzaprav gre. Nove in nove raziskave že desetletja potrjujejo, da je običajne snovi, iz katere smo ljudje in Zemlja in planeti pa sonce in vse druge zvezde v vseh stotinah milijard galaksij v vesolju … za pičlih 5 odstotkov. Kar je za nas običajno, je v vesolju tako rekoč izjema. Večino zavzemata t. i. temna snov in temna energija. Odkrivanje nečesa, kar je v temelju tako zelo drugačno, pa seveda terja, da na kar najbolj inovativen način uporabimo vse možne metode detekcije dogajanja tam zunaj. Imamo teleskope v vesolju in na Zemlji, ki skupaj pokrivajo tako rekoč celoten elektromagnetni spekter sevanja, z detektorji lovimo nevtrine in kozmične delce, v zadnjih letih pa prisluškujemo tudi gravitacijskim valovom.Vsi ti prijemi seveda obetajo, da bomo odkrili in razumeli marsikaj, kar je ta hip še neznano in nerazumljeno, vendar pri tem ne gre spregledati, da se sodobna astrofizika srečuje tudi z zagatnimi težavami. Eno najbolj perečih predstavljajo velike konstelacije satelitov, kakršna je današnji Starlink podjetja SpaceX, obetajo pa se še številne druge, ki bi število satelitov v nizki Zemljini orbiti lahko dvignile na več 10 000. To pa predstavlja resno težavo tako za astronomijo kot za naš dostop do vesolja. Zakaj? – Odgovor iščemo v tokratni Intelekti; gosta oddaje sta prof. dr. Andreja Gomboc s Centra za astrofiziko in kozmologijo Fakultete za naravoslovje Univerze v Novi Gorici in prof. dr. Tomaž Zwitter s Fakultete za matematiko in fiziko Univerze v Ljubljani.

A new image from the Event Horizon Telescope collaboration, which includes researchers and telescopes of the University of Arizona, has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A*, or Sgr A*. Seen in polarized light for the first time, this new view of the monster lurking at the center of our Milky Way galaxy has revealed a magnetic field structure strikingly similar to that of a much more massive black hole, known as M87*, at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden jet in Sgr A*. The results were published on March 27 in the journal The Astrophysical Journal Letters. Learning more about black holes and their magnetic fields Scientists unveiled the first image of Sgr A* - which is approximately 27,000 light-years from Earth - in 2022, revealing that while the Milky Way's supermassive black hole is more than a thousand times smaller and less massive than M87's, it looks remarkably similar. This made scientists wonder whether the two shared common traits outside of their looks. To find out, the team decided to study Sgr A* in polarized light. Previous studies of light around M87* revealed that the magnetic fields around the black hole giant allowed it to launch powerful jets of material back into the surrounding environment. Building on this work, the new images have revealed that the same may be true for Sgr A*. Boris Georgiev, an EHT postdoctoral researcher at UArizona's Steward Observatory and co-author on the study, said: "The consistency of magnetic field structures around Sgr A* and M87* suggests that the processes by which black holes feed and eject jets into their surroundings may be universal, despite their vast differences in size and mass." "What we're seeing now is that there are strong, twisted and organized magnetic fields near the black hole at the center of the Milky Way galaxy," said Sara Issaoun, NASA Hubble Fellowship Program Einstein Fellow at the Center for Astrophysics | Harvard & Smithsonian and co-lead of the project. "Along with Sgr A* having a strikingly similar polarization structure to that seen in the much larger and more powerful M87* black hole, we've learned that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them." Light is a moving oscillation of electric and magnetic fields that allows us to see objects. Sometimes, light oscillates in a preferred orientation, also known as polarized. Although polarized light surrounds us, to human eyes it is indistinguishable from "normal," or non-polarized, light. In the plasma around these black holes, particles whirling around magnetic field lines impart a polarization pattern perpendicular to the field. This allows astronomers to see in increasingly vivid detail what is happening in black hole regions and map their magnetic field lines. "By imaging polarized light from hot glowing gas near black holes, we are directly inferring the structure and strength of the magnetic fields that thread the flow of gas and matter that the black hole feeds on and ejects," said Angelo Ricarte, Harvard Black Hole Initiative Fellow and project co-lead. "Polarized light teaches us a lot more about the astrophysics, the properties of the gas and mechanisms that take place as a black hole feeds." But imaging black holes in polarized light isn't as easy as putting on a pair of polarized sunglasses, and this is particularly true of Sgr A*, which is changing so fast that it doesn't sit still for pictures. Imaging the supermassive black hole requires sophisticated tools above and beyond those previously used for capturing M87*, a much steadier target. Dan Marrone, EHT co-principal investigator and a co-author of the paper who is a professor of astronomy at Steward Observatory, and his team developed instruments that detected the polarized radio ...
Seeing a black hole's magnetic personalityScientists using the Event Horizon Telescope have produced a new image of the supermassive black hole at the centre of our galaxy. And this image is a little different: it captures the powerful magnetic fields that are acting as the cosmic cutlery feeding mass into the singularity. Avery Broderick is part of the Event Horizon Telescope team, he's also a professor at the University of Waterloo's Department of Physics and Astronomy, and associate faculty at the Perimeter Institute for theoretical physics.Decoding how chickadees maintain a mental map of their food cachesChickadees have an uncanny ability to recall thousands of secret stashes of food with a centimetre-scale precision. Salmaan Chettih, a postdoctoral researcher in neuroscience at Columbia University, investigated how chickadees encode their internal treasure maps. In his study in the journal Cell, he found the chickadee brains produce a unique pattern of activity — akin to a neural “barcode” — that marks the X on its mental treasure map. Italians don't just speak more with their hands, they speak differentlyResearchers comparing Swedish speakers with Italian speakers have found that the gestures they commonly use to accompany spoken language are quite different in kind. Lund University scientists Maria Graziano and Marianne Gullberg recorded the hand gestures study participants used when describing a children's cartoon to their friends. According to the results published in a Frontiers in Communication journal, Swedish speakers used gestures that concretely represented the subjects of their speech, while Italian speakers used abstract gestures more related to emphasis. What came first, the drumstick or the omelette?New archaeological work along the famous Silk Road trade route between Asia and Europe has added to the picture of how the chicken was brought from its southeast Asian homeland to the rest of Eurasia. An international team of researchers, including archaeobotanist Robert Spengler, analyzed tiny eggshell fragments from the soil of multiple sites in Central Asia. Their findings, published in Nature Communications, suggest that the motivation for domesticating the fowl was not the chicken, but their eggs. LED lighting is bright, efficient, and perhaps a problemThe global transition to LED lighting seems to be having some concerning impacts on the natural world and human health. These energy efficient artificial lights produce different spectra than older incandescent technology, or the natural light of the Sun that life on Earth evolved with over billions of years. LED lighting is brighter, bluer, and more widely used than incandescent lighting. Glen Jeffery, a professor of neuroscience from University College London, said that as a result, we may be paying the price with our health due to being oversaturated with blue light and starved of red and infrared light. In a new study in the Journal of Biophotonics, he found that exposing people to red and infrared light lowered their blood glucose levels by “charging up” our cells' energy production.Artificial light at night is also having “a profound impact” on our environment in how it affects plants and wildlife and the ecosystems they're in, according to Kevin Gaston, a professor of biodiversity and conservation at the University of Exeter. He said for nocturnal animals, the challenge they face from light pollution is the equivalent to humans losing daylight during the daytime. His review was published in the Annual Review of Environment and Resources.
#243As we age our immune systems do too, making us less able to fight infections and more prone to chronic inflammation. But a team of scientists has been able to reverse these effects in mice, rejuvenating their immune systems by targeting their stem cells. But there's a long road to trying the same thing in humans.Have you seen the incredible new black hole image? Just a couple of years since the Event Horizon Telescope's first, fuzzy image of Sagittarius A* – the black hole at the centre of our galaxy – a new picture offers a closer look. The stunning image released this week features the spiralling lines of Sgr A*'s magnetic field, which is seeding new questions about how black holes behave.Millions of tonnes of unexploded ordnance litter the globe from conflicts both ongoing and long past. And as time passes these bombs are not getting any less dangerous – new research finds some are actually becoming more prone to exploding.Physicists have theorised that there is a particle called the graviton that carries the force of gravity – much like a photon carries light, or a gluon carries the strong nuclear force. But the graviton has so far remained elusive. Now, researchers think they've seen one, or at least a particle with the correct properties to be a graviton. How this experiment unfolded, and why even a possible sighting is exciting to theorists.Plus: How a bad night's sleep makes you feel older; why therapy horses get stressed when they don't have a choice; and a robot that can design, build and test paper planes.Hosts Christie Taylor and Sophie Bushwick discuss with guests Grace Wade, Alex Wilkins, Michael Le Page and Karmela Padavic-Callaghan.

Die Africa Millimeter Telescope-projek is onder die gesamentlike leiding van twee spanne by die Radboud Universiteit Nijmegen en die Universiteit van Namibië en het ten doel om 'n 15m enkelskottel-radioteleskoop op die Gamsberg te realiseer. Die hoofdoel daarvan is om 'n noodsaaklike skakel te verskaf met die netwerk van teleskope regoor die wêreld, bekend as die Event Horizon Telescope, wat onlangs die eerste foto ooit van 'n swart gat vrygestel het. Dit was die eerste direkte bewyse vir die bestaan van swart gate, wat toon dat Einstein se teorie van algemene relatiwiteit reg was. Kosmos 94.1 Nuus het gesels met professor Michael Backes, hoof van die Namibiese H.E.S.S. groep en medeprofessor in die departement fisika aan die Universiteit van Namibië.

Are we living in a golden age of space telescopes? As our minds are being collectively blown by the images of our universe beginning to come from the JWST, our host Dr. Charles Liu and co-host Allen Liu explore the next space telescope on the horizon, the Nancy Grace Roman Space Telescope, with our guest, astronomer Dr. Alexandra Greenbaum, PhD. Dr. Greenbaum is an astronomer at Caltech working on the NGRST, which is set to launch in 2027. Named after Nancy Roman, who created NASA's space astronomy program and is known to many as the “Mother of Hubble,” it's a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics. As always, though, we jump into the day's joyfully cool cosmic thing, the incredible first picture of Sagittarius A Star, (Sgr A*), the supermassive black hole at the center of our Milky Way galaxy taken by the Event Horizon Telescope. Dr. Greenbaum explains that the EHT uses signals from many telescopes around the world to gather the data that is combined into images like this stunning photo. Alexandra works at IPAC, the Infrared Processing and Analysis Center at Caltech, on the Roman Telescope's coronagraph instrument, which is going to pave the way for future space photography of exoplanets. The coronagraph eliminates the glare that stars produce and allows astronomers to directly image planets in orbit around them. It will be far more powerful than any other coronagraph ever flown, seeing planets that are almost a billion times fainter than their host star. Our first question this week comes from Isaac, who asks how the JWST differs from the Hubble. Dr. Greenbaum explains how the JWST's mirror is made of 18 different mirror segments, whereas Hubble has a single mirror. Also, JWST is an infrared telescope, while Hubble functions primarily with the optical and ultraviolet portions of the spectrum. That means that JWST can see the light from stars stretching back to the earliest periods of our universe. Chuck and Alex also discuss how the NGRST differs from Hubble and the JWST. It primarily features a wide-field instrument that can look at a huge portion of the sky with different kinds of detectors. The coronagraph instrument is actually a technology demonstration that will help us develop the optical systems to see planets that are otherwise obscured by the overpowering light of the sun they orbit. Dr. Greenbaum also worked on the JWST, and she explains how each one worked to remove solar interference from planets or brown dwarfs orbiting stars. For our second question, Jayla from North Andover wants to know what's most exciting about Alexandra's job as an astronomer. She describes traveling to telescopes all around the world as an observational astronomer before the pandemic, and how wonderfully open and collaborative the field of astronomy is. Last but not least, Chuck, Alexandra, and Allen talk about what she's just read: “Parable of the Sower” by Octavia E. Butler, and how that book helped strengthen her commitment to her career studying the universe. If you'd like to know more about Dr. Greenbaum's work and keep up on the developments with the Nancy Grace Roman Space Telescope, you can check out roman.ipac.caltech.edu.

Join Hugh Ross and Fazale “Fuz” Rana as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, as well as new discoveries that point to the reality of God's existence. The Milky Way Galaxy's supermassive black hole is exceptionally small, about 35 times less massive than spiral galaxies of a similar size. The first-achieved image of its event horizon by the Event Horizon Telescope reveals an exceptionally quiet radiation level. What is the intensity and variability of our galaxy's supermassive black hole's radiation just outside its event horizon? What do this intensity and variability imply for advanced civilization on Earth? How much longer can we count on our galaxy's supermassive black hole being quiet enough for civilization on Earth? For many people, the shared ERV sequences in the human and great ape genomes evince common ancestry and an evolutionary origin for humanity. Yet, new discoveries about the physiological role of ERVs suggest another interpretation of ERVs in the human genome. Biochemist Fuz Rana discusses the latest insight into ERV molecular biology and explores the question: “Can a creation model explain the occurrence of ERV sequences in the human genome?” In this episode, Hugh and Fuz discuss these important topics.
Join Hugh Ross and Jeff Zweerink as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, as well as new discoveries that point to the reality of God's existence. Large galaxies and galaxy clusters, acting as gravitational lenses, allow astronomers to observe supernova eruption events occurring in much more distant galaxies. Such observations provide astronomers with the opportunity to determine cosmic creation parameters during that part of the early history of the universe where previously they could make only ballpark determinations. It's now within astronomers' grasp to obtain high precision measurements of the entire history of the universe. These measurements promise to provide a more detailed and comprehensive confirmation of the biblical cosmic creation model and for Jesus Christ as the Creator of the universe and everything that it contains. Using the Event Horizon Telescope, astronomers have now imaged a second supermassive black hole—the one at the center of our Milky Way Galaxy. The technology required for these observations is remarkable, and the data will give us important insight into how this black hole affects our galaxy. Will this data help us gain tools to probe quantum gravity? What do these insights tell us about the habitability of the Milky Way? In this episode Hugh and Jeff discuss these important topics.

"We humans are just specks of dust on a slightly bigger speck of dust in the immeasurable vastness of space. We can't cause stars to explode, we don't set the wheels of galaxies spinning, and it is not we who span the vault of heaven above us. But we can marvel at the universe and ask questions about it. We can have faith, hope, and love in this world-and this makes us stardust of a very special kind." —Dr. Heino Falcke We tend to think that science and spirituality are mutually exclusive. But for Dr. Heino Falcke, a belief in something bigger complements his understanding of the universe. Dr. Falcke is a Professor of Astroparticle Physics and Radio Astronomy at Radboud University. He is also the author of Light in the Darkness: Black Holes, the Universe, and Us. On this episode of Reversing Climate Change, Dr. Falcke joins Ross and cohost and Nori advisor David Addison to discuss the origin of carbon molecules and describe what drew him to the study of black holes. Dr. Falcke explains how he captured the first photograph of a black hole through the Event Horizon Telescope project, sharing what he learned from collaborating with 350 other astrophysicists on EHT and how we might apply those learnings to other global challenges like climate change. Listen in to understand why the complex systems of the universe are inherently unpredictable and learn how Dr. Falcke bridges the gap between the scientific and the spiritual world.

European Southern Observatory (ESO) released groundbreaking new Milky Way results from the Event Horizon Telescope Collaboration (EHT). Today I speak to Shep Doeleman Founding Director of the Event Horizon Telescope about. what it all means! You can watch the press conference on ESO's YouTube channel https://youtu.be/rIQLA6lo6R0 and watch my breakdown of everything you need to know! Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes. The image is a long-anticipated look at the massive object that sits at the very center of our galaxy. Scientists had previously seen stars orbiting around something invisible, compact, and very massive at the center of the Milky Way. This strongly suggested that this object—known as Sagittarius A* (Sgr A*, pronounced "sadge-ay-star")—is a black hole, and today's image provides the first direct visual evidence of it. Although we cannot see the black hole itself, because it is completely dark, glowing gas around it reveals a telltale signature: a dark central region (called a “shadow”) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun.

As COVID Cases Rises, Effectiveness Of Vaccines Lessens In Kids As parts of the country continue to see waves of infection from the omicron variant of COVID-19, parents of children over age five have taken heart at the availability of vaccines—while parents of kids five and under have continued to wait for an approved dose. But even as the case numbers continue to climb, the vaccines are less effective against the more-virulent omicron variants—and, for some reason, dramatically less effective in kids. Koerth joins Ira to discuss the story, and why experts say it's still worthwhile getting vaccinated even if the vaccines don't have the dramatic performance seen at the beginning of the vaccination phase of the pandemic. They also talk about a bird flu outbreak troubling poultry farms around the world, the odd immune system of the sleepy lizard, and how scientists are trying to catch a whiff of the odors of ancient Egypt. Meet The ‘Gentle Giant,' Your Friendly Neighborhood Black Hole It wasn't long ago that the idea of capturing an image of a black hole sounded like a joke, or an oxymoron. How do you take a picture of something so dense that it absorbs the very light around it? But three years ago, we got our first good look with help from the Event Horizon Telescope, which is actually multiple radio telescopes all linked together. That picture was a slightly blurry, red-and-orange doughnut—the best picture to date of the supermassive black hole at the center of a galaxy called Messier 87, which is called Messier 87* or M87*. (Black holes are given an asterisk after the name of their location). Today, it's possible to buy jewelry and t-shirts with that picture, drink out of a M87*-adorned coffee cup, or just make it your phone background. Now that the first picture of a black hole is practically a pop culture meme, how do you one-up that? In the past weeks, the Event Horizon Telescope team alluded to a new ‘breakthrough' hiding in the Milky Way. On Thursday, the team unveiled that breakthrough: the first image of our nearest black hole neighbor in the heart of our galaxy. Sagittarius A* is a “gentle giant,” says Feryal Ozel, a member of the global collaboration that created this image. It consumes far less of the gas swirling nearby than M87*, and is far fainter as a result. The Milky Way's black hole also lacks the galaxy-spanning jets of M87* and, due to its smaller size, the gas around it moves so fast that it took years longer to capture a clear picture. Ira talks with Ozel about what it takes to obtain such a picture, and what it can tell us about the extreme, high-temperature physics of black holes throughout the universe. What Was It Like To Witness The End Of The Dinosaurs? 66 million years ago, a massive asteroid hit what we know today as the Yucatán Peninsula of Mexico. Many people have a general idea of what happened next: The age of the dinosaurs was brought to a close, making room for mammals like us to thrive. But fewer people know what happened in the days, weeks, and years after impact. Increased research on fossils and geological remains from this time period have helped scientists paint a picture of this era. For large, non-avian dinosaurs like Triceratops and Tyrannosaurus rex, extinction was swift following the asteroid impact. But for creatures that were able to stay underwater and underground, their post-impact stories are more complicated. Joining Ira to discuss her book The Last Days of the Dinosaurs is Riley Black, science writer based in Salt Lake City, Utah. Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
