Podcasts about M87

Our home galaxy, the Milky Way, belongs to a small cluster of galaxies – the Local Group. It has fewer than a hundred known members. But most galaxies reside in much more impressive clusters. And the closest of these is centered in the constellation Virgo, which steps up the eastern sky this evening. The Virgo Cluster contains roughly 2,000 galaxies. They move through space together, bound by their mutual gravitational pull. The cluster’s most impressive member is Messier 87. It marks the center of the cluster, more than 50 million light-years away. M87 may span a million light-years and contain trillions of stars – many times the corresponding values for the Milky Way. And its total mass is more than twice the Milky Way’s. M87 is a different type of galaxy. The Milky Way is a spiral – a flat disk highlighted by “arms” of bright stars that make it look like a pinwheel. M87, on the other hand, is elliptical – it resembles a fat, fuzzy football. It may have grown so large through the mergers of several big galaxies. That scrambled the stars, so they orbit the center of M87 in all directions. The heart of the galaxy harbors a black hole more than a thousand times the mass of the central black hole in the Milky Way. It was the first black hole to have its picture taken – a dark shadow at the heart of a giant galaxy. More darkness in Virgo tomorrow. Script by Damond Benningfield

Did you know our universe has scars that could hold the key to time travel? These cosmic scars, called cosmic strings, are massive, invisible cracks in space-time left over from the early universe. Scientists believe that if we could find and understand them, they might reveal ways to bend time itself! Some theories even suggest that traveling along these cosmic strings could let us jump between different moments in history. It sounds like science fiction, but top physicists are taking it seriously. If these scars really exist, they could change everything we know about time and space!

From stargazing as a child to helping lead the team which took the first ever image of a black hole, Heino Falcke has only seen his faith and his work as an astronomer as deeply connected. In this episode we talk about his book, Light in the Darkness: Black Holes, the Universe and Us, where Falcke shares more about what creating the image actually consisted of, and some wisdom he picked up along the way. New discoveries will always challenge and redefine our old frameworks of thought, but Falcke shows us that this change is not fundamental, that it is a humbling reminder that our finite knowledge of the infinite God is always partial. Heino Falcke and his team's image of the black hole at the center of galaxy M87 reminds us of a message from Paul—that we now see through a glass, darkly; then, face to face.

Scientists found a black hole's twin, and somehow, it's even scarier than the first one. This cosmic monster is massive, lurking in the depths of space, swallowing everything that comes too close. What makes it even creepier? It's eerily similar to another supermassive black hole we already know—meaning there could be more of these lurking around the universe. Scientists are now racing to figure out how it formed and what it means for our understanding of black holes. One thing's for sure: space just got a little more terrifying!

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.

Muistatko vuonna 2019 julkistetun ensimmäisen kuvan mustasta aukosta? Kansainvälinen tutkijaryhmä onnistui kuvaamaan M87-galaksin keskellä olevan jättimäisen mustan aukon – tai oikeastaan kuvassa oli sen varjo.Kuva ei kuitenkaan ole tavallinen kuva, vaan se on tehty millimetrialueella toimivien radioteleskooppien signaaleita yhdistelemällä ja käsittelemällä. Suomen suurin radioteleskooppi on Metsähovin radio-observatorio. Siellä on yksi 14 metriä halkaisijaltaan oleva lautasantenni suuren kuvun sisällä ja useita pienempiä antenneja. Aalto-yliopistoon kuuluva radio-observatorio on mukana kansainvälisissä interferometrihankkeissa ja suomalaistutkijat ovat kehittäneet tätä mullistavaa tekniikkaa osaltaan eteenpäin. Haastateltavana Metsähovin radio-observatorion johtaja Joni Tammi ja radiointerverometriaan erikoistunut tähtitieteilijä Tuomas Savolainen. Toimittajana Jari Mäkinen.

Charles Gammie is a professor at the University of Illinois at Urbana-Champaign. Born with an insatiable curiosity and a love for mathematics, Dr. Gammie's journey to the forefront of astrophysics was anything but ordinary. Despite initially having ambitions of becoming a lawyer, a serendipitous encounter with a wise advisor steered him toward statistics and physics. Little did he know, this fateful decision would set him on a path toward the cosmos, propelling him into the world of astrophysics and a PhD he never envisioned. Today, Dr. Gammie stands as a theoretical and computational astrophysicist whose research focuses on black holes, and the formation of stars, moons, and planets, where he has developed numerical methods for modeling relativistic plasmas, relativistic radiation magnetohydrodynamics, and radiative processes in hot plasmas. Notably, Dr. Gammie co-led the theoretical modeling efforts for the Event Horizon Telescope (ETH) project, enabling the interpretation of the EHT data and the groundbreaking first-ever image of a supermassive black hole at the center of the M87 galaxy. This unprecedented collaboration across continents and disciplines showcased human ingenuity and the pursuit of knowledge. In this conversation, Dr. Gammie shared profound insights into black holes, their mechanics, spinning nature, and implications for understanding time and space. He also explored existential topics like extraterrestrial life and reconciling science with religious beliefs, offering inspiring advice for young minds to embrace curiosity and the unconventional. From the origins of "black holes" to the nature of time itself, this conversation was a captivating odyssey through the cosmos, guided by a brilliant scientific mind. This is The UIUC Talkshow, and this is our conversation with Dr. Charles Gammie.

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 ...

The Space, Astronomy & Science Podcast.SpaceTime Series 27 Episode 40*Magnetic Mysteries at the Milky Way's HeartThe Event Horizon Telescope has revealed organized magnetic fields swirling at the periphery of Sagittarius A*, the supermassive black hole at the Milky Way's core. In a groundbreaking observation, astronomers have captured these fields in polarized light, finding remarkable similarities to the black hole in galaxy M87. This discovery suggests that strong magnetic fields could be a universal trait among black holes, influencing how they interact with their surrounding matter. The study's implications stretch far beyond the iconic Sagittarius A*, offering a glimpse into the enigmatic behavior of black holes and their powerful ejections into space.*The Birth of Blue Supergiants Through Stellar MergersBlue supergiants, some of the universe's most luminous and massive stars, have long puzzled astronomers due to their abundance and solitary nature. A new study posits that these cosmic behemoths, often found alone, could be the result of binary star systems merging. This revelation, derived from simulations and observations in the Large Magellanic Cloud, challenges previous theories and suggests that stellar mergers play a pivotal role in the life cycle of galaxies and their stellar populations.*Webb Telescope Unveils the Star-Forming Tendrils of NGC 604NASA's James Webb Space Telescope peeks into NGC 604, a vibrant nursery of star formation within the Triangulum Galaxy, M33. Webb's infrared gaze has uncovered the intricate dance of star birth, highlighting massive blue stars and intricate gas filaments. This detailed view of NGC 604, a region teeming with over 200 massive stars, offers astronomers a rare opportunity to study these celestial giants at a critical stage in their evolution, providing new insights into the complex processes that shape galaxies.*New Crew Arrives at the International Space StationThe Soyuz MS-25 mission has successfully delivered a trio of spacefarers to the International Space Station after an initial launch delay. The mission continues the tradition of international partnership in space, as the ISS remains one of the few collaborative ventures between Russia and the West amidst geopolitical tensions.For more SpaceTime and to support the show, visit our website at https://spacetimewithstuartgary.com where you can access our universal listen link, find show notes, and learn how to become a patron.

Com observações feitas pela primeira vez em luz polarizada, a nova imagem do monstro que se esconde no coração da Via Láctea revelou um campo magnético com uma estrutura muito semelhante à do buraco negro situado no centro da galáxia M87, sugerindo que campos magnéticos intensos podem ser comuns a todos os buracos negros. Esta semelhança aponta também para a existência de um jato oculto em Sgr A*. Os resultados foram publicados hoje na revista da especialidade The Astrophysical Journal Letters. Em 2022, os cientistas revelaram a primeira imagem de Sgr A* durante conferências de imprensa em todo o mundo, incluindo no Observatório Europeu do Sul (ESO). Embora o buraco negro supermassivo da Via Láctea, que se encontra a cerca de 27 000 anos-luz de distância da Terra, seja pelo menos mil vezes mais pequeno e menos massivo do que o de M87, o primeiro buraco negro a ser fotografado, as observações revelaram que os dois têm um aspeto bastante semelhante, o que levou os cientistas a perguntarem-se se estes buracos negros partilhariam características comuns para além da sua aparência. Para o descobrir, a equipa decidiu estudar o Sgr A* em luz polarizada. Estudos anteriores da luz em torno do buraco negro de M87 (M87*) revelaram que os campos magnéticos à sua volta permitiam que o buraco negro lançasse poderosos jatos de material para o seu meio circundante. Com base neste trabalho, as novas imagens revelaram agora que o mesmo pode ser verdade para Sgr A*. FONTE: https://www.eso.org/public/portugal/news/eso2406/?lang #BLACKHOLE #UNIVERSE #EHT

With the help of ALMA, astronomers have obtained a new image of the supermassive black hole at the centre of the M87 galaxy.

This episode contains: Steven and Devon finally recap their visit to Austin, Texas. There were live shows, uncharted adventures and gaming, oh my! Ben was not only left out of their adventures, but his house is still causing grief. Oof.  https://uncharteredadventures.com/  https://vigilantebar.com/  Machine Learning Makeover: Iconic image of M87 black hole just got a machine-learning makeover. Using PRIMO (principal-component interferometric modeling), scientists used data from the EHT (Event Horizon Telescope) and 30,000 simulated images of black hole to produce a high fidelity image of the black hole at M87. It's amazing.  https://arstechnica.com/science/2023/04/iconic-image-of-m87-black-hole-just-got-a-machine-learning-makeover/  Diggin' A Hole: The Deepest Hole Ever Dug By Humans Had To Be Destroyed. The Kola Superdeep Borehole was 40,230 feet deep, but only has 4.5 stars on Google. Huh. We chat about the history of the hole and what science can be done with a superdeep holes. 14 species of fossilized microorganisms were found among other things. (But no screaming.)  https://www.iflscience.com/the-deepest-hole-ever-dug-by-humans-had-to-be-destroyed-68110  Big Question: Is there inherent order in nature or is it all chaos and chance? We chat about this, quite extensively. We talk about nature, observation, self-organization, entropy, heat-death, the circle of life and being zen. It's quite the discussion.  Star Trek Picard: The third and final season is over, and we give our thoughts. We very much enjoyed the finale, and we talk about all the things that worked in favor of the show. Which begs the question: what happened with the first two seaons?! We're fully prepared to say goodbye to Picard, but we're all in on a Star Trek Legacy show.  12 Monkeys: Steven had such fun with the third season of Picard, that he investigated another Terry Matalas show, 12 Monkeys. Sure, it's based on that awesome movie, but it's also so much more.   

M87 is a beast. The galaxy is bigger than our home galaxy, the Milky Way. It contains many more stars than the Milky Way — trillions in all — and has a total mass up to a couple of hundred times the Milky Way's. And the black hole in its center may be a thousand times the mass of the Milky Way's. One thing that M87 doesn't have is good looks. Instead of a beautiful spiral, it's an elliptical galaxy. It looks like a fat yellow rugby ball, with a bright middle surrounded by a hazy puffball of stars. Astronomers aren't sure how M87 got that shape, but they're working on it. Unlike spiral galaxies, where the stars all move in an orderly fashion, the stars in ellipticals move pretty much randomly. The stars' orbits are stretched out. And ellipticals contain little gas for making more stars. That may mean the galaxies formed from the mergers or two or more giant spirals. A merger could stir up the stars in the original galaxies, and trigger a huge outburst of star formation as clouds of gas ram together. The remaining gas would then be blown out of the galaxy. On the other hand, ellipticals could have formed from the collapse of massive clouds of gas. That would give birth to many stars, which then blow away the remaining gas — creating plain but “beastly” galaxies. M87 is well up in the east-southeast at nightfall, in the middle of a triangle formed by the bright stars Denebola, Arcturus, and Spica.  Script by Damond Benningfield Support McDonald Observatory

We return to Orlando Nerd Nite for a live recording where we take a look at the exciting upcoming missions to the Moon and the ESA mission to Jupiter's moons, JUICE, now on its 8 year journey to its destination. We revisit the amazing image of the supermassive black hole in the galaxy M87, now even amazing-er thanks to the clever implementation of artificial intelligence by some good old fashioned human intelligence.

On this week's show: The shadow of Milky Way's giant black hole has been seen for the first time, and bottlenose dolphins recognize each other by signature whistles—and tastes  It's been a few years since the first image of a black hole was published—that of the supermassive black hole at the center of the M87 galaxy came about in 2019. Now, we have a similar image of the black hole at the center of the Milky Way—our very own galaxy. Staff Writer Daniel Clery joins host Sarah Crespi to discuss why these images look so much alike, even though M87's black hole is 1600 times larger than ours. We also discuss what's next for the telescope that captured these shots. Also this week, we take to the seas. Bottlenose dolphins are known to have a “signature whistle” they use to announce their identity to other dolphins. This week in Science Advances, Jason Bruck and colleagues write about how they may also recognize other dolphins through another sense: taste. Jason, an assistant professor in the department of biology at Stephen F. Austin State University, talks with Sarah about what this means for dolphin minds. In a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor, interviews Gary Michelson, founder and co-chair of Michelson Philanthropies, about the importance of supporting research in the field of immunology—and where that support should be directed. This segment is sponsored by Michelson Philanthropies. This week's episode was produced with help from Podigy.

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.
