Astronomy Cast Ep. 750: Supernova Early Warning System By Fraser Cain & Dr. Pamela Gay Streamed live on Mar 31, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay When enormous stars detonate as supernovae they release a burst of neutrinos that can be the first sign of a coming explosion. Now, astronomers have built a network to watch for that flash of neutrinos, and help direct their telescopes for when the sky show begins. Supernovae explosions occur in stages, with neutrinos being emitted hours before photons. If we can accurately detect those neutrinos, we might just be able to get on target before the light show even starts.... Maybe.

Listeners of the show will know that there are compelling reasons to believe that these conclusions are based on questionable assumptions at the very heart of physics. This conversation, between a liquid sun proponent, a scientist who has spent his career studying the mainstream, and an appreciator of finely crafted theories, is an opportunity to lay these questionable assumptions on the table and to see how they hold up to scrutiny. Dr. Banik is also an invited speaker at our Beyond the Big Bang gathering in Portugal this summer, and has graciously agreed to serve as a counterbalance to those who say that the Big Bang Theory doesn't have much life left in it.

How do we know so much about supernovae, when all we see is this little point of light getting brighter and then dimmer over time? Given this minimal data, we can often say what type of star exploded, and even some details about how the explosion took place. Supernova astronomers are a lot like forensic scientists dusting for fingerprints and getting DNA samples at the scene of a crime. But instead of a typical crime scene, they are investigating the death of an entire solar system. Dr. Lindsey Kwok is a CIERA fellow at Northwestern University and an expert at using JWST to perform state-of-the-art forensic supernova science.
Physicists studying a distant galaxy using a telescopic technique called gravitational lensing, or telescopic magnification, have discovered over 40 previously unknown stars. The discovery, published in Nature Astronomy, shows how these stars were behaving eight billion years ago, giving a glimpse into the population of stars at 'cosmic noon' - the Middle Ages of the Universe. The research was led by the Centre for Frontier Science at Chiba University, in Japan, and involved over 45 international partners. In the UK this was led by Durham University's Centre for Extragalactic Astronomy and involved the Jodrell Bank Centre for Astrophysics, Manchester University. New telescopic magnification trick to discover over 40 new stars The international team used observations from the James Webb Space Telescope (JWST) and gravitational lensing to study a galaxy known as the Dragon Arc, located behind a massive cluster of galaxies called Abell 370. In gravitational lensing a foreground galaxy cluster bends the light from a more distant object and magnifies it, allowing scientists to study the distant object (here the Dragon Arc galaxy). Due to its gravitational lensing effect, Abell 370 stretches the Dragon Arc's signature spiral into an elongated shape - like a hall of mirrors of cosmic proportions. Using this technique, and high-resolution images from the JWST, taken across a full year, the team was able to identify 44 previously unknown stars in the Dragon Arc. They observed that the brightness of these individual stars changed over the course of the study due to variations in the gravitational lensing landscape. The findings show what this galaxy is made of in a way not previously achieved. They also tell us more about dark matter - a mysterious substance that binds together galaxies, creating the environment for stars, planets and life to exist. Dr David Lagattuta from the Centre for Extragalactic Astronomy at Durham University said: "When the team made this discovery, we knew that, given the size of the dots seen in the JWST images, the most logical explanation was that these were individual stars, seen for the first time, which is a hugely exciting discovery. "We know these are stars that have not been seen before by comparing them to previous image of the Dragon Arc which do not show these bright dots. "Other possibilities such as these findings being a cluster of stars or exploding supernovae simply did not fit the data. "It would be a huge coincidence to find so many supernovae all in the same galaxy and all exploding at the same time. Supernovae also tend to suppress star formation, but spectroscopy tells us the Dragon Arc is still actively forming stars. "We also reasoned that these objects had to be individual stars, rather than star clusters, since the size of what we're seeing (after accounting for the extreme lensing magnification) is much too small to fit in the tens of hundreds of bright stars in a star cluster at once. Many of the stars identified through this study are 'red supergiants', a type of star that has typically been very difficult to identify outside of the Milky Way. This is because they are covered in a layer of cosmic 'dust' making them almost invisible to telescopes. The JWST enabled the research team to peer through this dust more easily, revealing the hidden stars inside. Professor Mathilde Jauzac from the Centre for Extragalactic Astronomy and the Institute for Computational Cosmology at Durham University said: "This is the first time, that we are aware of, that so many stars have been discovered in one cluster. This finding enables us to see what the galaxy is made of in ways not possible before. "This provides a fascinating and unique view into the behaviour of stars at the critical 'cosmic noon', the Middle Ages of the Universe. "We know that in the early stages of the Universe there is lots of gas and early 'protostars' and then by nine to 10 billion years ago star formation peaks and everythin...
Wenn wir in einer klaren Nacht in den Himmel schauen, können wir eine atemberaubende Vielzahl an funkelnden Punkten beobachten. Doch der Blick in den Sternenhimmel liefert immer nur zweidimensionale Bilder. Die dritte Dimension der Himmelsobjekte – also ihre Entfernung zur Erde – ist nicht so leicht zu bestimmen. Mit welchen Methoden Astronominnen und Astronomen den Kosmos dennoch vermessen und welche bedeutende Rolle das Bestimmen von Entfernungen im Weltall heute noch spielt, berichtet Hendrik Hildebrandt von der Universität Bochum in dieser Podcastfolge von Welt der Physik. *** Ein Beitrag von Julia Thomas, gesprochen von Ulrike Kapfer.

If you're speaking English, not Latin, do you really have to say "supernovae" instead of "supernovas"? Also, they are, in some sense, created equally: explosion of a white dwarf, but the outcomes are not all equal. You are welcome for this grammatical tangent, and please enjoy our fun discussion about weird tesserae (more Latin!) on Venus and the whole standard candle story of type 1a supernovae gets a rewrite. On this episode of Walkabout the Galaxy, you can also enjoy solar energy/spacecraft trivia, space news, and general hilarity at no extra charge.
Massive events across the planet from comets in our skies, brightening supernova, record breaking hurricanes and now the economy begins to wobble. Are we at the civilization cycle reset again?
In dieser Folge geht es um Sternexplosionen – die natürlich nicht wirklich krachen, denn im leeren Weltraum kann man nichts hören, wie wir später klären. Zuerst geht es aber in den Space News ausführlich um die kürzlich gestarteten Raummissionen Hera und Europa Clipper. Danach hanteln wir uns durch die Sternexplosionen – Flareausbrüche, Novae, Kilonovae, Supernovae, Hypernovae und GRBs.

Supernovae are some of the most powerful explosions in the Universe, releasing more energy in a moment than most stars will release in their entire lifetimes. There are a few places in the Universe that defy comprehension. And supernovae have got to be the most extreme places you can imagine. We're talking about a star with potentially dozens of times the size and mass of our own Sun that violently dies in a faction of a second. Faster than it take me to say the word supernova, a complete star collapses in on itself, creating a black hole, forming the denser elements in the Universe, and then exploding outward with the energy of millions or even billions of stars.

Embark on a celestial journey with today's episode of Astronomy Daily - The Podcast, where your host, Anna, brings you the latest cosmic updates. We'll dive into the successful launch of SpaceX's Starlink satellites, incredible new images from the Hubble Space Telescope, and the real-time awakening of a massive black hole. We'll explore how Earth's atmosphere protects us from the devastating effects of nearby supernovae and look at a fascinating collaboration between Lego and space agencies to celebrate upcoming lunar missions. Stay tuned for an engaging and insightful episode as we dive into some of the most intriguing stories this week.On June 18, SpaceX successfully launched another batch of its Starlink broadband satellites from California, marking the 61st orbital liftoff of the year for the company. A Falcon 9 rocket carrying 20 satellites lifted off from Vandenberg Space Force Base at 11:40 p.m. EDT. This launch included 13 satellites with direct-to-cell capabilities, making them even more adaptable for broadband communication. Eight and a half minutes after launch, the Falcon 9's first stage made a pinpoint landing on the drone ship "Of Course I Still Love You" stationed in the Pacific Ocean. This was the fifth flight and landing for this particular booster, highlighting SpaceX's commitment to reusability and cost efficiency in space travel. The rocket's upper stage continued its journey to deploy the 20 satellites into low Earth orbit, adding to the ever-growing Starlink mega constellation, which now boasts over 6000 operational satellites.NASA's Hubble Space Telescope has successfully captured its first new images since switching to a single gyro operational mode. Despite issues with one of Hubble's gyroscopes, the transition to single gyro mode has proven effective, allowing Hubble to resume its vital scientific missions. One of the standout achievements in Hubble's new operational mode is a stunning image of the galaxy NGC 1546, located in the constellation Dorado. This image is part of a collaborative observing program involving both Hubble and NASA's James Webb Space Telescope. The program also employs data from the Atacama Large Millimeter/submillimeter Array, providing scientists with a comprehensive and detailed view of stellar formation and evolution.NASA has announced that Boeing's Starliner capsule will remain docked at the International Space Station for an additional four days, postponing its return to Earth until June 26. The extension will provide valuable time to gather more comprehensive data from this 20-day test flight, which is the first to carry astronauts aboard the Starliner. This delay comes as a precautionary measure to address ongoing technical challenges. The Starliner has experienced five known helium leaks in its propulsion system and has faced unexpected issues with numerous maneuvering jets. Engineers have determined that the spacecraft still has ample helium reserves to ensure a safe trip back to Earth. Meanwhile, astronauts Barry "Butch" Wilmore and Sunita Williams will use the extra time to contribute to ISS operations, aiding with experiments and maintenance tasks.In an extraordinary breakthrough, astronomers have reportedly documented what might be the first real-time observation of a massive black hole awakening. The galaxy SDSS J1335+0728, which appeared unremarkable in years past, began to shine brighter than ever starting in late 2019. Scientists tracking this phenomenon use data from multiple space and ground-based observatories, concluding that the significant behavioral changes are likely due to the sudden activation of the galaxy's central black hole. This groundbreaking observation could offer new insights into the mechanisms and behaviors inherent to galactic cores.New research confirms that Earth's atmosphere, especially the ozone layer, plays a critical role in protecting life from the harmful effects of nearby supernovae. The ozone layer, along with the magnetosphere, acts as a formidable shield against the intense UV radiation and cosmic rays that accompany these massive stellar explosions. A study published in Nature Communications Earth and Environment reveals that even a nearby supernova explosion within 100 parsecs, or 326 light-years, would not significantly harm Earth's biosphere. This resilience underscores the robust nature of Earth's defenses, allowing its biosphere to thrive even amidst galactic phenomena.LEGO, in partnership with ESA and NASA, is celebrating the Artemis program by releasing special space-themed bricks. This collaboration aims to inspire the next generation of space enthusiasts and commemorate the upcoming missions to the moon. The Artemis program's goal is to return humans to the lunar surface for the first time in over 50 years. These unique LEGO sets will not only capture the imagination of children and adults alike but also help raise awareness and excitement for future space exploration endeavors.For an astronomical experience, visit our website at astronomydaily.io for the latest news, sign up for our free newsletter, and check out exclusive sponsor deals.

When a star explodes, it's not finished having an impact on its surroundings. For the next thousand years or so, we can still see it as a supernova remnant, when the explosion has expanded to large enough scales that we can actually resolve an image of the explosion with modern telescopes like JWST, and it's even possible to do a forensic analysis to learn more about the cause of death. We will be talking about supernova remnants with Dr. Soham Mandal, who just recently earned his PhD from Purdue University.
Supernovae are the most powerful explosions in the universe, unleashing enough energy to outshine galaxies. We have no real metaphor for their power – if the sun were to magically go supernova it would feel like you were being hit by the energy of a nuclear explosion, every second. For weeks. While supernovae are the engines of creation, forging the elements that enable life, they also burn sterile whole regions of galaxies. So what would happen if one hit earth?

In this episode of Space Nuts Q&A, Andrew and Fred answer questions about supernovae, 3D printed telescopes, the Voyager space probe missions, and the possibility of using particle collision in space. They discuss how supernovae explosions do not blow away the gravitational field and how neutron stars develop as a result. They also provide insights into 3D printed telescopes and suggest that beginners may find it easier to start with an off-the-shelf telescope. They talk about the trajectory and potential fate of the Voyager spacecraft and discuss the challenges of building particle colliders in space. Overall, they provide informative and engaging answers to the audience's questions. Takeaways Supernovae explosions do not blow away the gravitational field because gravity is associated with mass. The explosion only affects the outer envelope of the star, while the core collapses to become a neutron star. 3D printed telescopes can be a good option for beginners, but it may be easier to start with an off-the-shelf telescope. 3D printed telescopes require more components and may involve more fiddling around. The Voyager spacecraft will continue on their current trajectories and are not expected to pass near any star systems within human lifetimes. However, if they were near enough to Earth, they could be detectable by extraterrestrial intelligence. Building particle colliders in space is challenging due to the need for precise guidance and the high velocities of the particles. It may be more cost-effective and realistic to continue building particle colliders on Earth. The fate of the Voyager spacecraft is uncertain, but they could potentially be captured into orbit around another star or collide with other objects. They will likely outlast our species and continue on their trajectories away from the solar system.

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.

Join Hugh Ross and Jeff Zweerink as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, including the reality of God's existence. Too Many Early Galaxies The James Webb Space Telescope (JWST) has revealed about ten times as many galaxies within the cosmos's first 420 million years as what some big bang creation models predict. Astronomers are searching for an explanation for this overabundance of early galaxies. Possible scenarios include a high number of supernova events during the universe's first 420 million years. Different big bang models predict different average star masses and different star formation rates during the universe's first half billion years. It will take at least another year of JWST observations to determine which of these big bang creation models correctly describes very early and later epochs of cosmic history.

AI Easily Fooled Powerful large language models (like ChatGPT) have demonstrated remarkable abilities to provide solutions to problems that require complex reasoning. Yet researchers want to discern the level of understanding by the AIs (artificial intelligence), just as a teacher wants to know how well a student comprehends a correct answer they provided. A recent study shows that despite generating good answers, AIs have very little understanding of the issues involved. Specifically, when confronted with challenges that involved absurdly wrong facts (like 8 x 7 = 14), the AIs will disavow the previous answer and apologize for being mistaken. This research demonstrates that, while AIs accomplish impressive tasks, they do not demonstrate some essential features of “intelligence.” Resources: Can ChatGPT Defend Its Belief in Truth?

There's a bright supernova in a nearby galaxy, and a very distant supernova made brighter by the beauty of gravitational lensing. In another galaxy, a gargantuan black hole is revealed to be orbited by another supermassive black hole, resulting in a gamma ray flares as it rips through the main black hole's accretion disk. Closer to home, we learn about new asteroid missions and a rapidly warming planet (hint: it's ours). Plus: Harrison Ford and Leonard Nimoy trivia!
