Podcasts about supernovae

Supernovae are among the most powerful events in the universe. This episode explores what happens when stars reach the end of their lives and why these immense explosions can briefly outshine entire galaxies. Along the way, you'll hear about famous supernovae, distant galaxies, observational astronomy, scientific classification, and the ongoing effort to understand these remarkable cosmic phenomena. It's steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!

Das Weltall wirkt still, kalt und weit weg. Doch manchmal reicht ein Ereignis in unserer kosmischen Nachbarschaft aus, um Spuren auf der Erde zu hinterlassen. In dieser Folge sprechen wir über Supernovae: explodierende Sterne, radioaktive Signaturen auf dem Meeresboden und die Frage, ob kosmische Katastrophen die Geschichte des Lebens beeinflusst haben könnten. Wie nah müsste eine Sternenexplosion sein, um für die Erde gefährlich zu werden? Und ist unser Planet vielleicht viel stärker mit der Milchstraße verbunden, als wir im Alltag glauben?

Episode: S05E112 — Tuesday, 26 May 2026 Hosts: Anna & Avery Network: Bitesz.com Podcast Network Website: astronomydaily.io  |  Social: @AstroDailyPod   Story Summaries 1. NASA Unveils Ambitious Moon Base Plan As this episode was recorded, NASA Administrator Jared Isaacman was preparing to announce a landmark plan for a permanent human outpost at the lunar south pole by 2036. The programme carries a price tag of approximately $30 billion across a seven-year foundational phase, relies on nuclear power systems, leverages lunar water ice for fuel and life support, and effectively retires the Gateway orbital station concept. Commercial partners will supply rovers and habitat modules. Phase one targets around two dozen lunar launches, including Artemis IV, by 2028. Full details will be covered in tomorrow's episode. 2. Starship V3 Flight 12 — Engine Drama, Historic Debut SpaceX launched the first Starship V3 rocket on Friday, 22 May 2026, from brand-new Pad 2 at Starbase, Texas. Ship 39 reached space and completed a controlled splashdown in the Indian Ocean despite losing one of its six vacuum Raptor engines during ascent. The flight computer compensated by extending burns on the remaining five. The Super Heavy booster was lost in the Gulf of Mexico after a failed boostback burn. The FAA has opened a review. SpaceX declared most pre-planned test objectives met. 3. JWST Maps First Daily Weather Cycle on a Distant World Published in Science on 21 May 2026. Researchers from Johns Hopkins and Arizona State Universities used Webb's NIRISS instrument to observe WASP-94Ab — a hot Jupiter 690 light-years away — and detected the first daily cloud cycle ever recorded on another planet. Thick magnesium silicate clouds form each morning, then completely clear by evening. The finding also corrected a decade of skewed atmospheric composition data. 4. NASA's Fermi Telescope Solves 20-Year Supernova Mystery An international team led by Fabio Acero used NASA's Fermi Gamma-ray Space Telescope to confirm the first definitive gamma-ray detection from a superluminous supernova — SN 2017egm. The data confirms a newly formed magnetar as the power source behind these extraordinarily bright explosions. Published in Astronomy & Astrophysics, 2026. 5. Most Rocky Exoplanets May Lack Earth-Like Metallic Cores A new paper submitted to the Astrophysical Journal challenges the long-held assumption that dense metallic cores are standard features of rocky planets. Researchers argue that most rocky exoplanets may have formed without Earth-style metallic cores — meaning no global magnetic field, with significant implications for atmospheric retention and habitability. 6. The Soviet Rover That Went Silent — and Came Back Lunokhod 1 was the world's first remote-controlled rover on another world (1970). After traversing 10.5 km of Mare Imbrium, contact was lost in 1971. For nearly 40 years its exact position was unknown — until NASA's Lunar Reconnaissance Orbiter identified it in 2010. The APOLLO project then fired laser pulses and received ~2,000 photons back from its French-built retroreflector — four times stronger than expected. It remains an active contributor to lunar science today.   Sources & Further Reading •       NASA Moon Base announcement: nasa.gov/2026-news-releases •       Starship Flight 12 updates: space.com •       WASP-94Ab paper: Science, 21 May 2026 — DOI via Johns Hopkins Hub •       Fermi supernova paper: Astronomy & Astrophysics, 2026 — DOI: 10.1051/0004-6361/202558547 •       Exoplanet cores paper: submitted to Astrophysical Journal, May 2026Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

https://www.youtube.com/watch?v=OEZu3pXAFWY Hosted by Fraser Cain. From Jan 31, 2020. In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.   This clearly wasn't a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.   More than a decade after that cosmic explosion, astronomers finally think they know what series of events led to the release of this much energy, now called a superluminous supernova. A red giant ate a white dwarf. An event so rare it probably accounts for only 1 in 1,000 supernovae!   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

In dieser Folge widmen sich Franzi und Karl dem Feedback zu den letzten drei Geschichten im AstroGeo Podcast. Zunächst freuen sie sich über zwei Nachrichten, die zeigen, wie der Podcast das Interesse für die Geologie und die Astronomie weckt: Geologie-Fans finden über den Podcast Zugang zu den Sternen, während Astronomie-Begeisterte die Erde für sich entdecken. Ein großes Thema ist die geplante AstroGeo-Exkursion (Franzi sagt: „Der Wandertag!“) ins Nördlinger Ries im Oktober 2026. Die Nachfrage war deutlich höher als die Zahl verfügbarer Plätze, weswegen einige Hörerinnen und Hörer enttäuscht waren - , aber auch Vorfreude und Unterstützung wurde geäußert. Der Plan ist, Teile der Exkursion des Wandertags aufzunehmen und als Sonderfolge zu veröffentlichen. Zur ersten Alpen-Folge über falsch herum gelagerten Gesteinsdecken gibt es Korrekturen und Ergänzungen, etwa zu sprachlichen Details (Schweizerdeutsch) und geologischen Erklärungen (Faltenbildung, Sediment- vs. Plutonische Tiefengesteine). Karl geht auch auf Missverständnisse ein und kündigt eine dritte, abschließende Folge zur Gebirgsbildung an. Da es für nicht-Expertinnen und -Experten schwierig sein kann, sich ein überschobenes Deckengebirge vorzustellen – denn das sind die Alpen – haben sich Franzi und Karl auch über Feedback in Form von methodischen Vorschlägen gefreut. Dazu gehören bessere Visualisierungen mit farbigen Handtüchern für die Idee einer liegenden Falte (von Albert Heim bis 1906 anstelle von überschobenen Decken propagiert): Foto 1: Das rote Tuch steht für die primär unten liegende ältere Gesteinseinheit, und das blaue für die darüber abgelagerte jüngere. Foto 2/3: Hier kann man leicht bei der Bildung einer liegenden Falte erkennen (propagiert von Albert Heim), dass dann im unteren Schenkel der Falte die Abfolge umgekehrt wurde. Foto 4: Die reale Deckenüberschiebung lässt sich ebenfalls leicht nachstellen: Das ältere (rote) Gestein wurde hier über die jüngere Schicht (blau) geschoben). Zur Supernova-Folge loben viele die Verständlichkeit und den Humor. In ihrem inhaltlichen Feedback diskutieren Hörer jene „fehlgeschlagenen“, oder auch „gescheiterten“ Supernovae, bei denen Sterne direkt zu Schwarzen Löchern kollabieren, ohne vorher eine spektakuläre Explosion abzuliefern. Außerdem gab es Post von einem Hörer, der von seiner ganz eigenen „gescheiterte“ Supernova berichtet hat: die Supernova SN 1987A in der Nachbargalaxie der Großen Magellanschen Wolke. Zuguterletzt geht's noch um um die Social-Media-Kanäle des AstroGeo-Podcasts: Hier ist Mastodon der einzige. Karl erklärt, wie Mastodon funktioniert – und frei zugänglich reinschauen kann man hier: https://chaos.social/@astro_geo

Während Sterne wie unsere Sonne ihre Entwicklung recht unspektakulär als Weiße Zwerge beenden, erwartet massereichere Sterne ein weitaus spannenderes Schicksal: Sie enden als Neutronensterne oder gar als Schwarze Löcher. Doch bevor es soweit ist, explodieren sie als Supernova – und hier findet das eigentliche Spektakel statt: Für kurze Zeit können diese Sterne so hell leuchten wie ihre gesamte restliche Heimatgalaxie. Explodiert eine solche Supernova in der Milchstraße, könnte sie sogar hell genug aufleuchten, um mit bloßem Auge am Tageshimmel sichtbar zu sein. Irgendwann wird es auch für den Stern Beteigeuze so weit sein: Bislang kennen und schätzen wir ihn als Schulterstern des prominenten Wintersternbilds Orion. Er ist einer der hellsten Sterne am gesamten Himmel. Beteigeuze ist schon kein „normaler“ Stern mehr, sondern ein Roter Überriese – ein Stern, der seine Entwicklung schon bald beenden wird und von dem sich Forschende sicher sind, dass er in den nächsten paar Millionen Jahren als Supernova explodieren wird. Aber was wäre, wenn Beteigeuze am Ende seiner Entwicklung nicht explodieren würde – sondern einfach so, heimlich, still und leise, vom Himmel verschwinden würde? Wenn er also nicht erst als Supernova explodiert, sondern einfach direkt zu einem Schwarzen Loch kollabiert? In dieser Folge erzählt Franzi von potenziell gescheiterten Supernovae. Bislang ist unklar, ob es solche „Un-Novae“ überhaupt gibt – Supernova-Explosionen, die aus irgendeinem Grund ausfallen. Es gibt einige Indizien, die dafür sprechen, dass es solche gescheiterten Supernovae geben könnte. Doch wie sucht man nach etwas, das sich dadurch auszeichnet, das es nicht stattfindet? Die Suche ist eine astronomische Fleißarbeit – doch kürzlich verkündeten Forscherinnen und Forscher, das ihnen genau das gelungen sei: In der Andromedagalaxie soll ein Himmelskörper mit der Bezeichnung M31-2024-DS1 direkt zum Schwarzen Loch kollabiert sein – ohne als Supernova zu explodieren.

Hat die Wissenschaft die dunkle Energie drei Jahrzehnte lang falsch verstanden? In dieser neuen Folge gehen wir genau dieser Frage nach – und zwar mit brandaktuellen Daten, die das Fundament der modernen Kosmologie ins Wanken bringen könnten. Wir reisen noch einmal zurück zur Entdeckung der beschleunigten Expansion Ende der 90er Jahre, erklären, wie Supernovae damals zu einer Revolution geführt haben, und warum die Hubble-Konstante inzwischen zum größten Problem des kosmologischen Standardmodells geworden ist. Was bedeutet das für das Schicksal des Universums? Für unsere bisherigen Annahmen? Und für die Frage, ob wir 30 Jahre lang ein fundamentales Detail übersehen haben? Eine Folge über Daten, Zweifel, Dynamik – und darüber, wie sich unser Blick auf das Universum gerade wieder verändert.

This finding contradicts previous theories suggesting that the expansion was accelerating due to dark energy. We delve into the implications of this research, which indicates that dark energy may be evolving more rapidly than previously understood, potentially marking a paradigm shift in cosmology. The episode discusses various scenarios for the universe's future, including the Big Crunch, Steady State theory, Big Freeze, and Big Rip, and how these new observations could reshape our understanding of cosmic fate.First Glimpse of the Sun's Polar Magnetic FieldAstronomers have captured their first detailed view of the Sun's polar magnetic field in motion, revealing unexpected rapid movements. The Solar Orbiter spacecraft has provided insights into the Sun's magnetic activity, which follows an 11-year cycle. This segment highlights the significance of the findings, which enhance our understanding of solar dynamics and the implications for space weather.Current Surge in Space Weather EventsAs the Sun reaches solar maximum, astronomers are observing increased solar storm activity, including multiple X-class and M-class solar flares. This segment discusses the effects of coronal mass ejections on Earth, including spectacular auroras and potential disruptions to technology and power grids. We explore the science behind solar flares and their impact on our planet, providing a comprehensive overview of current space weather conditions.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical SocietyAstrophysical Journal LettersNature GeoscienceJournal of the American Medical AssociationBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

In this episode of SpaceTime, we tackle the mysteries of the cosmos with a new mathematical model of the universe and ponder the age-old question: are we alone in the universe?New Model of the UniverseScientists have unveiled a groundbreaking mathematical model aimed at simplifying our understanding of the universe's evolution over the past 13.8 billion years. This innovative research, based on data from the Dark Energy Spectroscopic Instrument (DESI), offers fresh insights into the cosmic web's structure, revealing how dark energy influences cosmic expansion. Lead author Leonardo Gianni from the University of Queensland discusses how this model challenges existing paradigms and provides a clearer picture of the universe's complex behaviour, including the impact of voids and collapsing regions of matter.Are We Alone?A new study presented at the European Planetary Science Congress raises intriguing questions about the existence of intelligent alien civilizations. Researchers estimate that the nearest technological society in our galaxy could be over 33,000 light years away, with conditions on their home planets potentially mirroring those of Earth. The study highlights the challenges of sustaining advanced life and the long timelines required for such civilizations to coexist with humanity.Partial Solar EclipseToday, a partial solar eclipse graced the skies over New Zealand, the South Pacific, and parts of Australia and Antarctica. As the Moon passed between the Earth and the Sun, observers witnessed a stunning celestial display with up to 70% of the Sun's face obscured. This remarkable event serves as a reminder of the intricate dance of celestial bodies that shape our night sky.www.spacetimewithstuartgary.com✍️ Episode ReferencesPhysical Review Lettershttps://journals.aps.org/prl/European Planetary Science Congresshttps://www.epsc2025.eu/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.New Model of the UniverseAre We Alone?Partial Solar EclipseNew Model of the UniverseAre We Alone?Partial Solar Eclipse

More than two decades ago, Adam Riess's Nobel Prize-winning work fundamentally changed our understanding of the universe. His new work is reshaping cosmology for a second time. RESOURCES:Adam Riess, astrophysicist at Johns Hopkins University. SOURCES:"The Nobel Prize Winner Who Thinks We Have the Universe All Wrong," by Ross Andersen (The Atlantic, 2025)."The answer to life, the universe and everything might be 73. Or 67," by Hannah Devlin (The Guardian, 2018)."Adam G. Riess Nobel Prize Lecture," (The Nobel Foundation, 2011)."Breakthroughs 1998," by Floyd Bloom (Science, 1998)."Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant," by Adam Riess, Alexei Filippenko, Peter Challis, Alejandro Clocchiatti, Alan Diercks, Peter Garnavich, Ron Gilliland, Craig Hogan, Saurabh Jha, Robert Kirshner, Bruno Leibundgut, Mark Phillips, David Reiss, Brian Schmidt, Robert Schommer, Chris Smith, Jason Spyromilio, Christopher Stubbs, Nicholas Suntzeff, and John Tonry (The Astronomical Journal, 1998)."1912: Henrietta Leavitt Discovers the Distance Key," (Carnegie Institution for Science).

In this episode of SpaceTime, we uncover groundbreaking revelations about dark energy, lunar geology, and Europe's innovative space weather monitoring initiative.Dark Energy: A Changing Force?Astronomers have compiled the largest supernova dataset to date, revealing tantalizing hints that dark energy may not be a constant force in the universe. This research, led by the International Supernova Cosmology Project, analyzes over 2,000 Type 1A supernovae to explore the evolving nature of dark energy, which currently comprises nearly 70% of the universe's mass-energy content. The findings suggest that if dark energy is weakening, it could significantly impact the universe's expansion and ultimate fate, challenging existing models and sparking excitement in the astrophysics community.New Insights into Lunar MagmaA recent study analyzing samples from China's Chang' e 5 mission indicates that molten magma may have persisted on the Moon's surface much longer than previously believed. Researchers, led by Stephen Alado, utilized radioactive dating to reveal that volcanic activity on the lunar far side could have continued for billions of years, contradicting earlier theories about the Moon's cooling process. This new understanding of lunar geology offers valuable insights into the Moon's evolution and the processes that shape celestial bodies.Europe's Space Weather Early Warning SystemThe European Space Agency is set to launch Vigil, a pioneering space weather probe, in 2031.

For years, scientists have grappled with differing values derived from cosmic microwave background radiation and supernova observations. Lead author Wendy Friedman discusses how recent findings suggest that the standard model of cosmology holds up, with the Hubble constant now estimated at 70.4 kilometres per second per megaparsec, aligning more closely with earlier measurements. This breakthrough could reshape our understanding of the universe's expansion and evolution.Venus's Thin CrustNew research indicates that Venus's crust is unexpectedly thin, challenging previous assumptions about the planet's geology. A study published in Nature Communications reveals that Venus lacks the tectonic activity seen on Earth, resulting in a crust that is about 40 to 65 kilometres thick. This research proposes a model of crust metamorphism that could explain how volcanic activity persists on Venus, despite the absence of plate tectonics. Upcoming missions, including NASA's Davinci and Veritas, aim to gather more data that could confirm these findings and enhance our understanding of Venus's geological processes.Building Blocks of Stellar FormationA recent study highlights that the formation of stars is influenced not only by the amount of gas in a galaxy but also by its distribution. Observations from the WALLABY survey, conducted using the Australian Square Kilometre Array Pathfinder Telescope, reveal that star formation is concentrated in areas with higher gas density. Lead author Seona Lee explains how this research sheds light on the intricate processes that govern star formation, suggesting that gas location is critical for the birth of new stars across various galaxy types.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XNature Communicationshttps://www.nature.com/naturecommunications/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 66 for broadcast on 2 June 202501:00 Resolving the Hubble constant debate12:15 Venus's surprisingly thin crust22:30 Building blocks of stellar formation30:00 Science report: New links between autism and Parkinson's disease

Have you ever pondered the fact that the universe is expanding? And not only that, it's expanding at an increasing speed - meaning everything around us is getting further and further away? If that isolating thought makes you feel slightly panicked, don't worry: this programme also contains wine!Brian Schmidt is a Distinguished Professor of Astrophysics at the Australian National University, known for his work on supernovae: massive explosions that take place when stars come to the ends of their lives. They are among the most energetic events in the universe and incredibly difficult to find; but that's what his High-Z Supernova Search Team did, identifying enough of these rare and distant explosions to measure just how fast they were moving away from us.This led them to the realisation that, contrary to long-held belief in cosmology, the expansion of the universe was speeding up; a discovery which earned Brian a share of the 2011 Nobel Prize for Physics. As if that wasn't enough, he's gone on to discover one of the earliest stars in the universe; run a university; and become a winemaker, at his very own vineyard just outside Canberra.In a conversation spanning the genius phraseology of writer Douglas Adams, the importance of pisco sours, and the similarities between astronomy and viticulture, Brian tells Professor Jim Al-Khalili how his supernovae breakthrough paved the way for a revolution in astronomy - and where the field needs to go next...Presented by Jim Al-Khalili Produced for BBC Studios by Lucy Taylor

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....

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.

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?

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.   Team: Fraser Cain - @fcain Chad Weber - weber.chad@gmail.com Created by: Fraser Cain and Jason Harmer Edited by: Chad Weber Music: Left Spine Down - “X-Ray”   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

A nova is a star that periodically sheds mass in a huge flare-up of light and energy. This week, astrophysicist Dr. Carlos Badenes from the University of Pittsburgh joins us to discuss a star that should be going nova in the next few weeks--and will be visible in the night sky for about 6-7 days! T Corona Borealis (TCrB) is a binary system comprising two stars in the constellation Corona Borealis that bursts into magnitude 2 (as seen from Earth) about every 80 years--and should do so again by mid-September! Join us. Headlines: NASA's Perseverance rover discovers a rock on Mars that shows intriguing signs of potential ancient microbial life, sparking excitement among scientists Starliner Update: NASA and Boeing discuss the extended mission of the Starliner spacecraft, addressing concerns and highlighting the crew's safety and productivity Scientists uncover evidence suggesting Mercury's crust harbors a 10-mile thick diamond layer, formed by unique planetary processes Main Topic - The Visible Nova in the Sky Near You: T Coronae Borealis, a recurring nova located in the constellation Corona Borealis, is expected to become visible to the naked eye between now and September 2024 Novae are binary star systems where a white dwarf accumulates material from its companion star, leading to a thermonuclear runaway and a bright outburst Supernovae, in contrast, are the explosive deaths of stars, either through the complete disruption of a white dwarf or the collapse of a massive star's core Historical accounts of "new stars" include Tycho's Supernova (1572), Kepler's Supernova (1604), and the Crab Nebula progenitor (1054) Dr. Badenes discusses his research on novae in nearby galaxies and the use of the Hubble Space Telescope to study the progenitors of thermonuclear supernovae The crew explores the limits of recurring novae, the possibility of a white dwarf exploding as a Type Ia supernova, and the anticipated supernova of the star Betelgeuse in the constellation Orion Hosts: Rod Pyle and Tariq Malik Guest: Carlos Badenes Download or subscribe to this show at https://twit.tv/shows/this-week-in-space.

Today, Matt Powell explains to us why he doesn't believe that making a big pile of little things is possible. He might not ever come up with any new arguments, but there's always a new level of idiocy to be found

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.
