A couple of years ago, a space telescope discovered something odd about NGC 6505. The galaxy is encircled by a ring. It isn’t part of the galaxy itself. Instead, it’s an image of a background galaxy – one that’s billions of light-years farther. Einstein Rings are named for Albert Einstein because they were predicted by his theory of gravity. The gravity of a foreground object acts as a lens – it bends and magnifies the light of a background object. On small scales, gravitational lenses have revealed everything from black holes to rogue planets. Galaxies are much bigger and heavier, so they produce more dramatic lenses. Many of them create bright arcs. But when the alignment is just right, they can create a full circle. NGC 6505 is a good example. The galaxy is about twice the diameter of the Milky Way, and several times its mass. It’s about 600 million light-years away. The background galaxy is four billion light-years farther. The lensing effect has allowed astronomers to measure the amount of dark matter in the center of NGC 6505, as well as details about its stars – discoveries made possible by its beautiful ring. NGC 6505 is enwrapped in the coils of Draco, the dragon. The galaxy is more than a third of the way up the northwestern sky at nightfall. It’s visible through a small telescope. But you need a big telescope and a long exposure to make out its ring. Script by Damond Benningfield

La découverte récente de toutes petites galaxies très rouge à faible rayon (appelées des Little Red Dots, LRD) a potentiellement révélé un nouveau type de population galactique dans l'Univers primordial, caractérisée par de petits rayons effectifs (100 à 200 parsecs seulement) mais de grandes masses stellaires (plusieurs dizaines de milliards de masses solaires). Leur source d'énergie demeure incertaine : trous noirs supermassifs en accrétion ou une intense formation d'étoiles. Une équipe d'astrophysiciens à analysé les conséquences dynamiques de ces densités stellaires extrêmes et arrivent à la conclusion que les collisions d'étoiles doivent y être incontrôlées, menant à la naissance de trous noirs massifs en très peu de temps.

Aaron Welty: The Heroics of WeaknessAaron Welty grew up with his eyes on the stars — not just the ones overhead, but the ones in stories. Galaxies far, far away, rings of power, and caped crusaders filled his imagination. But while most kids left those adventures behind when the movie ended, Aaron carried them with him. For him, those tales weren't just entertainment — they were roadmaps pointing the way toward courage, sacrifice, and a bigger purpose.From the very start, Aaron's life has looked a bit like a hero's journey — not with blasters or superpowers, but with quiet strength and a steady resolve shaped by life's challenges.He recently shared more about that journey on the Cedarville Stories podcast, opening up about how God has worked through his weakness to create something beautiful and unexpected.Aaron was born 10 weeks early and diagnosed with cerebral palsy not long after. That alone could have written a different kind of story. But he kept going one chapter at a time: first as a student at Cedarville University, then as a staffer on Capitol Hill, and now as a speaker and author of a nearly finished trilogy of memoirs.His interest in public service took root back in the seventh grade, when a lesson on U.S. presidents sparked something inside him. Friends told him he'd make a great president someday, and instead of brushing it off, Aaron dared to believe them. That dream found real footing at Cedarville, where he studied public administration and graduated in 2005.He packed up for Washington, D.C. soon after, spending years working behind the scenes on Capitol Hill and later with the Department of Transportation. His focus? Advocating for disability inclusion and making sure workspaces welcomed everyone.“It was about affirming the dignity of work,” Aaron said. “Even if only 1% were affected, it mattered to that 1%.”But Aaron's impact isn't just in policy papers and meetings. Over the years, he's mentored high school and college students, often connecting with them through summer leadership programs. He doesn't shy away from the hard questions — in fact, he invites them. And more often than not, he draws on the stories that shaped him growing up.From Star Wars to Lord of the Rings to Marvel's sprawling universe, Aaron sees more than special effects — he sees lessons on calling, identity, and the grit it takes to keep going.“These stories aren't just for fun,” he said. “They're invitations — to think, to wrestle, to become.”Aaron knows a thing or two about wrestling. He's lived through pain and loss and disappointment. But rather than wish those things away, he's learned to see them differently.“God didn't take the pain away,” he said. “He gave me perseverance instead.”It's something he calls the “heroics of weakness” — a way of seeing suffering not as something to escape but as the place where purpose can be born. “So often, it's the thing we wish God would take away that ends up being the thing He uses most,” he said.One of the pictures Aaron clings to is from Scripture — the idea of fragile “jars of clay” carrying something far greater inside. That's how he sees his life: breakable, yes, but brimming with meaning.“You're not just here to be entertained,” he said. “You're here to engage — to become who you were meant to be.”And that's exactly what Aaron is doing. In a world chasing fame and titles, he's living something deeper — a quiet legacy of perseverance, presence, and purpose.https://share.transistor.fm/s/03c5d342https://youtu.be/Vv_OYW-paE4

Euclid Space Telescope's Groundbreaking Findings: The European Space Agency's Euclid mission is revolutionizing our understanding of galaxy evolution just a year into its operations. With the capability to observe over 1.2 million galaxies, Euclid is addressing fundamental questions about galaxy shapes and their formation history, paving the way for a modern galactic tuning fork diagram.The Spectacular Geminid Meteor Shower: The Geminid meteor shower is set to peak on December 13th and 14th, promising a dazzling display of bright and colorful meteors. With a waning crescent moon providing optimal viewing conditions, it's the perfect opportunity to witness this annual celestial event.Near Earth Asteroids Close Approaches: This week, several near-Earth asteroids will make close passes to our planet, including 2025 VP1, a bus-sized asteroid, and the larger 3361 Orpheus, which is about 1,400 feet wide. While classified as potentially hazardous, their trajectories are closely monitored, ensuring no immediate threat to Earth.Runaway Stars and the Large Magellanic Cloud: New research utilizing hypervelocity stars sheds light on the history of the Large Magellanic Cloud. By tracing the paths of stars ejected by a supermassive black hole, scientists gather evidence that could confirm its existence and provide insights into the galaxy's past.Andromeda's Satellite Galaxies: A study from Durham University reveals how Andromeda's satellite galaxies are quenched, revealing that many lose their star-forming capabilities long before they even approach Andromeda. This highlights the complex interactions within our cosmic neighborhood.For more cosmic updates, visit our website at astronomydaily.io.

Can an ultra-compact dwarf galaxy have a supermassive black hole at its center? Are there galaxies with supermassive black holes that are offset from their galactic centers? To find out, Dr. Charles Liu and co-host Allen Liu welcome “the other” Dr. Matt Taylor, an Assistant Professor of Astronomy at the University of Calgary, who joins us from the control room of the largest astronomical telescope in Canada, at the Rothney Astrophysical Observatory (RAO) in Alberta, Canada. As always, though, we start off with the day's joyfully cool cosmic thing, which starts with the discovery of a supermassive black hole in the middle of an ultra-compact dwarf galaxy M60-UCD1 located in the Virgo galaxy cluster. That led to the discovery of more 4 UCDs in the Virgo Galaxy Cluster and 1 in the Fornax galaxy clusters, but then the limits of technology prevented the discovery of any additional UCDs. But now, by using the James Webb Space Telescope, Matt and his fellow researchers (including Dr. Vivienne Baldassare, our former guest for Black Holes and Space Junk with Vivienne Baldassare) have just published a paper about their discovery that in the smallest, lowest mass UCD yet found, they found a roughly 2,000,000 solar mass black hole. Basically, that's a tiny galaxy to hold a supermassive black hole, and Matt is sure there are many more of these waiting to be discovered. After that Matt tells us about his atypical journey to astronomy, including his first career – as a professional chef. When cooking stopped being fun, Matt enrolled at a local community college and “moved from gastronomy to astronomy” as Allen puts it. Our first audience question comes from our Patreon Patron Taylor L, who asks, “Is it possible dark energy and the acceleration of the universe's expansion could be explained by the idea that the black hole we live in is constantly devouring matter from outside?” Matt passes on determining whether or not we live inside a black hole. But, he explains that while at the galactic level expansion is happening on a really large scale, at a smaller scale like our local group of galaxies (Milky Way, Andromeda, and local dwarf galaxies), our mutual gravitation counteracts that expansion. Matt goes on to discuss how accretion disks are what makes it possible to “see” a black hole, but that ultra-compact dwarf galaxies don't have gas and dust forming accretion disks. Instead, they use stellar velocities to find black holes in UCDs. Next up, Matt tells us about some of the research he's doing into archetypal compact elliptical (cE) galaxies, which have the mass of a giant galaxy put into the volume of a dwarf galaxy, and how black holes appear in these systems. And Matt dangles another upcoming paper about galaxies with supermassive black holes that are offset from their galactic centers. For our next audience question, Pshemo asks: “We often say gravity is weak compared to other forces. But in the right regimes, like near black holes and neutron stars, or on large cosmic scales, it dominates every other interaction. Should we stop calling gravity a weak force?” It's a thought-provoking question with an even better answer, so please watch or listen to the episode to hear it yourself from Matt. If you'd like to know more about Matt, you can check out his website, mataylor5128.github.io.

Galaxies frequently collide with each other, and the results can be spectacular. The encounters can pull out giant ribbons of stars. They can trigger intense bouts of starbirth. And they can scramble a galaxy’s stars and gas clouds, creating beautiful rings that look like cosmic bulls-eyes. One well-known galaxy that’s experienced a head-on collision is the Cartwheel. It’s about 500 million light-years away, in the constellation Sculptor, which is low in the south on November evenings. The Cartwheel is a good bit bigger than the Milky Way. It has a bright inner ring of mainly older stars that’s offset a little from the galaxy’s middle. A brighter ring of younger, bluer stars is far outside it. Wispy spiral arms that look like the spokes of a wagon wheel connect the rings, giving the “Cartwheel” its name. The Cartwheel probably started as a normal spiral galaxy. But a few hundred million years ago, a smaller galaxy plunged through it. The collision created a wave that rippled outward, like a rock thrown into a still pond. The wave disrupted the original spiral structure. It also squeezed clouds of gas and dust, causing them to give birth to new stars. And the drama isn’t over. Many more stars are being born in the outer ring, in giant nurseries that look like a strand of lights on a Christmas wreath. They will continue to make the Cartwheel shine brightly as it spins through the universe. Script by Damond Benningfield

In this episode of SpaceTime, we explore a trio of intriguing astronomical phenomena that are reshaping our understanding of the cosmos.Interstellar Comet 3I Atlas: A Close EncounterInterstellar comet 3I Atlas has reached its perihelion, passing closest to the Sun without any signs of alien life forms, despite wild media speculation. This episode discusses how the comet maintained its expected trajectory and velocity, while also revealing groundbreaking findings from NASA's Swift Space Telescope, which detected ultraviolet signatures of water from the comet, providing new insights into the chemistry of interstellar objects and their potential to harbour the building blocks of life.A Colossal Gas Bridge Between Dwarf GalaxiesAstronomers have discovered a massive bridge of neutral hydrogen gas linking two dwarf galaxies, NGC 4532 and DDO 137, located approximately 53 million light years away. This remarkable structure spans an astonishing 185,000 light years and is accompanied by a vast tail of gas extending 1 million light years. The findings shed light on how galaxies interact and evolve, particularly in dense environments like the Virgo Cluster, and offer crucial insights into the dynamics of galactic gas and star formation.Volcanic Eruptions and Hidden Ice on MarsA new study suggests that explosive volcanic eruptions on ancient Mars may have transported water ice to the equatorial regions of the Red Planet. Using computer modelling, researchers propose that water vapour released during these eruptions could have frozen in the Martian atmosphere, leading to the accumulation of significant ice deposits. This discovery could have profound implications for future human exploration of Mars, as it raises questions about the availability of water resources in unexpected locations.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Nature Communicationshttps://www.nature.com/naturecommunications/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Interstellar Comet 3I Atlas: A Close EncounterA Colossal Gas Bridge Between Dwarf GalaxiesVolcanic Eruptions and Hidden Ice on Mars

trädens löv prasslade under våra fötter.En: The air was clear, and the leaves on the trees rustled under our feet.Sv: Skolan hade ordnat en utflykt hit, vilket alltid var höjdpunkten på terminen.En: The school had organized a trip here, which was always the highlight of the term.Sv: Jag älskade de här stunderna.En: I loved these moments.Sv: Men jag kände också pressen av att hitta ett ämne till mitt nästa skolprojekt.En: But I also felt the pressure to find a topic for my next school project.Sv: Något som skulle göra mig speciell i lärarens ögon.En: Something that would make me stand out in the teacher's eyes.Sv: Inne i museet var det livligt.En: Inside the museum, it was lively.Sv: Svarta taveltavlor fulla av vetenskapliga formler sträckte sig högt över våra huvuden, medan vi rörde oss genom de olika utställningarna.En: Blackboards full of scientific formulas stretched high above our heads as we moved through the various exhibits.Sv: Jag stod där, funderade, försökte att inte känna mig så osäker i denna enorma värld av vetenskap och teknik.En: I stood there, pondering, trying not to feel so insecure in this enormous world of science and technology.Sv: "Elsa, vad letar du efter?"En: "Elsa, what are you looking for?"Sv: hörde jag plötsligt min klasskamrat Johan fråga.En: I suddenly heard my classmate Johan ask.Sv: Han kom upp bredvid mig, hans vanliga leende på plats.En: He came up beside me, his usual smile in place.Sv: Johan var smart.En: Johan was smart.Sv: Alla visste det.En: Everyone knew it.Sv: Men vad många inte visste var hans passion för astronomi.En: But what many didn't know was his passion for astronomy.Sv: Det hade jag sett när han hade pratat om stjärnorna, fast alltid i tysthet.En: I had noticed it when he talked about the stars, though always quietly.Sv: "Jag vet inte", svarade jag något försiktigt.En: "I don't know," I answered somewhat cautiously.Sv: "Jag behöver inspiration för mitt projekt."En: "I need inspiration for my project."Sv: Jag bestämde mig för att lämna det stora, bullriga rummet och hitta en lugnare plats.En: I decided to leave the large, noisy room and find a quieter place.Sv: Det fanns en del av museet som inte var så överfullt.En: There was a part of the museum that wasn't so crowded.Sv: Med ett leende följde Johan efter mig.En: Smiling, Johan followed me.Sv: Plötsligt hittade vi ett hörn av museet som nästan var gömt.En: Suddenly, we found a corner of the museum that was almost hidden.Sv: Det var ett rum tillägnat obskyra rymdprojekt.En: It was a room dedicated to obscure space projects.Sv: Displayerna var dammiga och åsidosatta, men de glittrade av historia och upptäckter.En: The displays were dusty and overlooked, but they sparkled with history and discoveries.Sv: Jag såg hur Johans ögon lyste upp.En: I saw how Johan's eyes lit up.Sv: "Har du någonsin sett något sådant här?"En: "Have you ever seen anything like this?"Sv: frågade han entusiastiskt.En: he asked enthusiastically.Sv: Han började förklara projekten, hans röst fylld med äkta passion och glädje.En: He began explaining the projects, his voice filled with genuine passion and joy.Sv: I det ögonblicket såg jag en annan sida av Johan, och jag blev inspirerad.En: In that moment, I saw another side of Johan, and I was inspired.Sv: Vi stannade där länge, glömde tid och rum.En: We stayed there a long time, losing track of time and space.Sv: Johans berättelser om rymdforskning och de anonyma hjältar som hade bidragit till dessa projekt fick mig att inse att här kanske, fanns det något nytt.En: Johan's stories about space research and the anonymous heroes who contributed to these projects made me realize that perhaps here, there was something new.Sv: Tillbaka i skolan fylldes jag av en ny typ av självförtroende.En: Back at school, I was filled with a new kind of confidence.Sv: Jag visste att jag hade hittat mitt projekt.En: I knew I had found my project.Sv: Det skulle handla om de dolda hjältarna i rymdforskning.En: It would be about the unsung heroes of space research.Sv: Johan hade visat mig att det är okej att ha dolda passioner, och att ibland kan de leda oss till oväntade och fantastiska platser.En: Johan had shown me that it's okay to have hidden passions, and that sometimes they can lead us to unexpected and fantastic places.Sv: Med denna nya insikt kände jag mig mer självsäker.En: With this new insight, I felt more confident.Sv: Och i den processen hade vi båda funnit något: jag min röst och Johan modet att visa sin sanna.En: And in the process, we had both found something: I found my voice and Johan the courage to show his true self.Sv: Utanför museet svepte den kalla vinden återigen runt oss, ett tecken på att den kalla säsongen höll på att börja.En: Outside the museum, the cold wind swept around us again, a sign that the cold season was about to begin.Sv: Men i våra hjärtan var vi varma, fyllda av hopp och nyfikenhet.En: But in our hearts, we were warm, filled with hope and curiosity.Sv: En skolsal fylld av möjligheter väntade, och vi var redo att ta oss an den.En: A classroom full of possibilities awaited, and we were ready to take it on.

The Milky Way is a giant among galaxies – a hundred thousand light-years in diameter. But a few galaxies make the Milky Way look like a mere bauble by comparison. They span millions of light-years – puffed up by the action of supermassive black holes. These monsters are known as giant radio galaxies. Not only are they large, but they produce enormous amounts of radio waves. The black hole in such a galaxy’s heart is encircled by a massive disk. As material in the disk spirals into the black hole, magnetic fields fire “jets” of some of its particles like water from a firehose. These jets can streak far into space. They end as they plow into the material between galaxies, forming “lobes” that are bright sources of radio waves. A recent study found 15 of these giants. They’re in the constellation Sculptor, which creeps low across the south on October evenings. The largest of them spans more than 12 million light-years. The galaxy itself is wider and heavier than the Milky Way. But the jets puff up its overall size. It actually has two sets of jets – one nested inside the other. The longer set is older – powered up by the black hole millions of years ago. But the black hole might have slowed down its eating for a while, shutting off that flow of particles. Later, it started chowing down again, powering the second set of jets, which continue to expand – sustaining this galactic monster. Script by Damond Benningfield

Messier 31, the Andromeda Galaxy, is the largest and most-distant object that’s easily visible to the unaided eye. Under dark skies, it looks like a skinny cloud about as wide as the Moon. Right now, it’s about a third of the way up in the northeast at nightfall. M31 is two-and-a-half million light-years away. In other words, the light you see from the galaxy tonight began its journey across the cosmos two-and-a-half million years ago. The galaxy is roughly 150,000 light-years across – bigger than the Milky Way – and may contain a trillion stars. It’s also the hub of its own galactic empire – it’s orbited by more than three dozen smaller galaxies. And a recent study revealed many new details about the satellites. Astronomers spent years looking at them with Hubble Space Telescope. And they supplemented the new observations by going through older ones. They found that most of the stars in the smaller galaxies had been born by about 12 billion years ago – when the universe was about one-tenth of its present age. And star formation had all but stopped by about eight billion years ago. Galaxies that are bigger and farther from M31 gave birth to stars a little longer than those that are small and close. One of the bigger satellites might have rammed through M31 a few million years ago. That stirred things up throughout the empire surrounding big, beautiful M31. More about M31 tomorrow.
