Podcasts about astronomers

From September 20, 2023. Hosted by Tony Darnell. Episode 39. In recent years, scientists have made great strides in the search for extraterrestrial life. They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it.   The search for life however, is a little more involved than finding planets, measuring their location and distance around the star and figuring out their location within a habitable zone.  Astronomers need more information to learn if life may be there.   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!

The “halo” that surrounds the Milky Way Galaxy is dark but heavy. It’s much more massive than the galaxy’s bright disk, but we don’t see much there. So the halo must be filled with dark matter. It produces no detectable energy, but it reveals its presence through its gravitational pull on the matter we can see. The leading idea says dark matter consists of some type of exotic particle. But efforts to find such particles have come up empty. Astronomers have also looked to see if the dark matter might consist of MACHOs – massive compact halo objects. The list of candidates includes faint stars, dead stars, black holes, free-floating planets, and brown dwarfs. Such objects are extremely faint. But they can sometimes brighten – not directly, but by magnifying the light of stars behind them. The technique is known as gravitational lensing. When one massive body passes in front of another, it causes the background object to get much brighter. The flare-up can last from hours to months. How long it lasts, and how much the background star brightens, reveals details about the lensing object. And that reveals the type of object. Searches for gravitational lenses have found many planets, faint stars, and even the first “rogue” black hole – one that couldn’t be seen any other way. But there just aren’t enough MACHOs to account for more than a small fraction of the dark matter – leaving us in the dark about its nature. Script by Damond Benningfield

Utilizing the advanced capabilities of the Australian Square Kilometer Array Pathfinder (ASCAP), researchers reveal the unique characteristics of these galaxies, including their powerful jets and lobes traveling at superluminal speeds. We delve into the implications of these findings for our understanding of galaxy formation and evolution.Changes on TitanNext, we discuss the intriguing changes occurring on Saturn's moon Titan, which is experiencing rapid orbital changes on geological timescales. Scientists explore the factors influencing Titan's tidal dissipation rate and what it reveals about the moon's internal structure and history. This study provides insights into the dynamic processes at play in our solar system's moons.Failed Soviet Spacecraft ReturnsWe also cover the dramatic re-entry of the Kosmos 482, a failed Soviet spacecraft that spent 53 years in orbit before crashing back to Earth. Launched in 1972 on a mission to Venus, the spacecraft's uncontrolled descent raises concerns about space debris and its potential impact on Earth.AI and Humanity's FutureFinally, we tackle the controversial topic of artificial intelligence and its potential risks to humanity. With AI evolving at an unprecedented pace, we examine the findings of a new study that assesses the likelihood of AI leading to human extinction. As science fiction warns of a future dominated by AI, we explore the reality of these threats and what they mean for our future.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvJournal of the American Medical Associationhttps://jamanetwork.com/journals/jamaBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space time series 28, episode 57 for broadcast on 12 May 202500:54 Astronomers have discovered 15 giant radio galaxies each hosting a supermassive black hole09:35 You're still learning about these galaxies11:57 Now you, uh, mentioned starburst galaxies earlier.

The NASA Kepler Spacecraft has discovered more than 2,000 planets which have been confirmed to be orbiting distant stars. It performs this remarkable feat by imaging more than 145,000 stars simultaneously to observe and measure the tiny dips in light which occur as a planet passes in front of its star. Astronomers have long known that many of the solar systems in the Milky Way have more than one star. To investigate the possibilities for life in a double star system, Dr Max Popp a scholar at Princeton University and Dr. Siegfried Eggl of Germany's Max Plank Institute substituted the real giant planet orbiting the stellar pair Kepler 35A and B with an Earth sized one orbiting the Kepler AB pair with periods between 341 and 380 days. Their detailed analysis is published in the journal Nature Communications.

Astronomers recently detected a signature of life on a distant planet. This does not mean that we have discovered aliens, but it's reasonable to wonder what is giving off this signal. We discuss the mission to find planets that are brimming with life — or are at least habitable. We also talk about why the search for life remains so intriguing to so many scientists. Our guest:Adam Frank, Ph.D., author and Helen F. and Fred H. Gowen Professor in the Department of Physics and Astronomy at the University of Rochester

Scientists have been seriously debating whether K2-18b, a planet 124 light-years away in the Leo constellation, could be an ocean world that hosts tiny life forms. Using the James Webb Space Telescope, a British-US team found two chemicals in its atmosphere — dimethyl sulfide (DMS) and dimethyl disulfide — that, here on Earth, are only made by living things like microscopic phytoplankton. They're being super careful though, saying we need a lot more data before shouting “alien life!” from the rooftops. Still, it's a massive deal, because K2-18b is in the habitable zone — not too hot, not too cold, just right for liquid water. It's more than eight times heavier and 2.5 times bigger than Earth, making it a rare, exciting find.

If a black hole shreds a star and nobody is around to hear it, does it make a sound? To find out, Dr. Charles Liu and co-host Allen Liu welcome Professor Yvette Cendes, (aka u/Andromeda321 on Reddit), a Radio Astronomer studying transient radio signals from space. As always, though, we start off with the day's joyfully cool cosmic thing, a report by the Dark Energy Survey that seems to show that the amount of dark energy originally described as the cosmological constant by Albert Einstein might in fact be variable. As Prof. Cendes explains, the data indicates that universal expansion is still accelerating but the rate might be changing. After Yvette explains what she does, and how radio astronomy works in concert with optical astronomy to deliver a more complete understanding, Chuck asks her to explain Tidal Disruption Events, or TDEs, about which she's a world expert. A TDE is when a star wanders too close to a supermassive black hole and ends up getting shredded. Yvette prefers to call them “Shredders.” Our first audience question comes from Nachama, who asks, “When will the black hole in the Milky Way eat the Sun?” The good news, according to Yvette, is that will never happen. As she explains, black holes actually don't suck any more than anything that massive would, and we're 25-30,000 light years away from Sagittarius A* – too far away to worry about. Next, Chuck asks Yvette about one of the most famous transient signals we've ever found, the so called “Wow!” signal detected in 1977 by Jerry Ehman at the now-defunct Xavier Observatory in Ohio. Because the signal looked exactly like what might be expected if it were of extraterrestrial origin, Ehman circled it on the printout and wrote, “Wow!” Unfortunately, it never repeated. The most likely explanation, according to Dr. Cendes, is that it was some sort of manmade interference, although the signal is currently being reinvestigated. Yvette recounts how she ended up ended up as a first-term professor at the University of Oregon after studying in the Netherlands and Toronto and working at Harvard. Then she answers an audience question from Yan Min, who asks, “Where is the best place in the world to study astronomy? I live in New York – Is it New York?” Unfortunately for Yankees fans, Yvette says it would most likely be Cambridge, Massachusetts thanks to Harvard, which has the biggest number of astronomers under one roof and operates the Chandra X-Ray Observatory, and M.I.T. on the other side of town if you get bored. Chuck asks Yvette what happens after a black hole shreds a star. Shredders, she explains, are rare. In our own Milky Way, they probably happen once every million years. Once a TDE is classified by optical astronomers, Yvette and her team point their radio telescopes at the tidal radius outside of the event horizon to discern the outflows weeks, months and even years after the initial event. He also asks Yvette if she has any hobbies to help her decompress from thinking about violent events in the universe. She likes to cross stitch, the “original pixel art.” Yvette shows us a cross stitch she made of the James Webb Space Telescope complex mirror, another featuring an 8-bit Mario screen with the words “What doesn't kill me makes me smaller,” and a third with objects in the Solar System. She also embroiders and shows us a hoop featuring the constellations visible in the northern hemisphere night sky. We end with Yvette and Allen schooling Chuck about Reddit's immense reach and value in scientific discourse. One subreddit, called r/Space, has “27 million intelligent lifeforms” subscribed to it. On Reddit, Yvette's username is u/Andromeda321, and she's one of the top users on the platform over 1 million karma points. She's known for starting her posts that explain or comment on recent discoveries with the phrase, “Astronomer here!” If you'd like to follow Dr. Yvette Cendes, you can find her on Reddit, where she's u/Andromeda321, and her dedicated subreddit, reddit.com/r/Andromeda321.

The beginnings of our end — where the anus came from Our distant evolutionary ancestors had no anuses. Their waste was excreted from the same orifice they used to ingest food, much like jellyfish do today. Now a new study on bioRxiv that has yet to be peer-reviewed, scientists think they've found the evolutionary link in a worm with only a single digestive hole. Andreas Hejnol, from Friedrich Schiller University Jena, said he found genes we now associate with the anus being expressed in the worms in the opening where its sperm comes out, suggesting that in our evolutionary history a similar orifice was co-opted as a butt hole. Deepfake videos are becoming so real, spotting them is becoming increasingly diceyDetecting deepfake videos generated by artificial intelligence is a problem that's getting progressively worse as the technology continues to improve. One way we used to be able to tell the difference between a fake and real video is that subtle signals revealing a person's heart rate don't exist in artificially generated videos. But that is no longer the case, according to a new study in the journal Frontiers in Imaging. Peter Eisert, from Humboldt University and the Fraunhofer Heinrich-Hertz-Institute HHI in Germany, said detecting manipulated content visually is only going to become a lot more difficult going forward. Crows can use tools, do math — and now apparently understand geometryCrows are known to be among the most intelligent of animals, and a new study has explored their geometrical sophistication. Researchers including Andreas Nieder from the University of Tübingen found that crows can recognize and distinguish different kinds of quadrilateral shapes, an ability we had thought was unique to humans. The research was published in the journal Science Advances.There's gold in them thar magnetically charged neutron stars!Astronomers have discovered a new source of the universe's heavy elements — things like gold, platinum and uranium. A study led by astrophysicist Anirudh Patel found that magnetars — exotic neutron stars with ultra-powerful magnetic fields — may produce these elements in a process analogous to the way solar flares are produced by our Sun. The research, published in The Astrophysical Journal Letters, found that a single flare from a magnetar could produce the mass equivalent of 27 moons' worth of these heavy elements in one burst.It may not be big, but it's small — and stroppyYou might not expect an insect so tiny you need a magnifying glass to see it properly to be an aggressive defender of its territory, but that's because you haven't met the warty birch caterpillar. Its territory is just the tip of a birch leaf, but it defends it by threatening intruders with vigorous, if not precisely powerful, vibrations. Jayne Yack at Carleton University has been studying this caterpillar since 2008. This research was published in the Journal of Experimental Biology.Criminals beware — the microbiome leaves fingerprintsScientists have developed a new tool that can track location based on traces of the bacteria characteristic to different places. Eran Elhaik, from Lund University in Sweden, trained the AI tool using nearly 4,500 microbiome samples collected around the world from subway systems, soil and the oceans. He said they could identify the city source in 92 per cent of their urban samples, and in Hong Kong, where a lot of their data came from, they could identify the specific subway station samples were taken from with 82 per cent accuracy. The study was published in the journal Genome Biology and Evolution.

The star Spica, which is quite close to the Moon tonight, is quite different from the Sun. It consists of two stars, not one. Both stars are many times bigger and heavier than the Sun. And their surfaces are tens of thousands of degrees hotter, so the stars shine blue-white. On the other hand, the Sun and Spica are made of almost exactly the same ingredients: mainly hydrogen and helium, with only a smattering of heavier elements. That composition was figured out by an astronomer who was born 125 years ago tomorrow, in England. Cecilia Payne caught the astronomy bug when she saw a lecture by Arthur Eddington, one of the world’s leading astronomers. She started her education in England, then finished in the United States. She earned a Ph.D. in 1925. And her doctoral thesis shook up the field. Decades later, in fact, Otto Struve, the first director of McDonald Observatory, called it the most brilliant thesis ever written in the field. Astronomers already had the techniques for measuring what stars are made of. Their work led them to believe that stars contain the same mixture of elements as Earth. But Payne used a new way to analyze the readings, taking into account the charge of atoms. She concluded that stars were made mainly of hydrogen and helium – elements formed in the Big Bang. By a few years later, just about everyone accepted her analysis – completely changing our concept of the stars. Script by Damond Benningfield

The surface of the Sun is like a pot of boiling water. Millions of bubbles of hot gas churn across it, constantly rising and falling. But the bubbles are a little bigger than those on your stovetop. The bubbles are known as granules. They form as energy from deep inside the Sun works its way to the surface. That heats the gas in the Sun’s top layer, forming bubbles. As they reach the surface, their gas cools and drops back into the Sun. This non-stop activity creates an easy-to-see pattern of bright blobs – the hot gas – with dark lanes between them – the cooler gas. The size of the granules varies from about a hundred miles to more than a thousand – big enough to swallow Texas. And each granule lasts for no more than about 20 minutes. A recent study said the granulation changes a bit during the Sun’s 11-year cycle of magnetic activity. Just after the peak of the cycle, there are slightly more granules than average, but they’re a little smaller than average. Other stars are so far away that we can’t see the granulation on most of them. But several types of observations confirm that they, too, are boiling away. Astronomers have seen granulation on a few stars. The stars are much bigger than the Sun. And they’re late in life, so they’re undergoing big changes. The granules on those stars are tens of millions of miles across – dozens of times the diameter of the Sun – giant bubbles of hot gas on giant stars. Script by Damond Benningfield

In 1816, 18-year-old Mary Wollstonecraft Godwin (later Shelley) birthed science fiction during a rainy vacation on Lake Geneva. Inspired by a vision of a man crouched beside the corpse he reanimated, Frankenstein warned of what happens when man tries to play God. Two centuries later, the monsters are real, and they're called Musk, Altman, and Zuckerberg. Today's tech titans, like Frankenstein's Victor, race to build superintelligent machines in their image: soulless wannabe-gods with devastating reach. Gil Duran, of the Nerd Reich newsletter, connects this to A.I. worship, quoting a billionaire obsessed with “creating God” through algorithms. M.I.T.'s annotated Frankenstein likens Victor's horror to Oppenheimer's nuclear regret. We've entered a new atomic age, but instead of bombs, it's information weapons and hacked minds. As Pulitzer-nominated journalist Carole Cadwalladr warns, this is what a digital coup looks like. A.I. is trained to replace journalists, strip away privacy, and deepen inequality, just as Gaslit Nation has warned since 2018. What's the answer? Community. Skill-sharing. Nature. The real world. Jack Welch, once worshipped like Musk is today, gutted G.E. with fear-based leadership. Now he's a cautionary tale. So will today's tech gods be. Mary Shelley saw it coming. “Frightful must it be,” she wrote. We agree. But there's power in human connection, in rejecting the machine's illusions. Frankenstein's monster was abandoned.

The gusty winds of spring make it a good season for flying a kite. But you might not want to try it on the planet Wasp-127 b – it would be hard to hang on. Winds high above the surface blow at an astounding 20,000 miles per hour – a hundred times faster than winds in the strongest category five hurricanes on Earth. The star – Wasp-127 – is a lot like the Sun. But the planet isn’t much like any planet in the solar system. It’s much wider than Jupiter, the largest planet. But it’s only one-sixth of Jupiter’s mass. That makes it one of the “puffiest” planets yet seen. Wasp-127 b was discovered because it passes in front of its parent star every four days. As it does so, starlight filters through the atmosphere. Astronomers use that effect to learn something about the atmosphere. Recent observations revealed that material in the upper atmosphere is moving extremely fast – blown by the fastest winds yet seen on any planet. The observations also suggested that there’s a big temperature difference between the dawn and evening skies – more than 300 degrees Fahrenheit – one more reason the planet isn’t a good place to fly a kite. The Wasp-127 system is in the constellation Sextans, the sextant. This evening, it’s well to the lower right of the Moon. But the system is more than 500 light-years away, so the star is too faint to see without a telescope. Script by Damond Benningfield

This remarkable finding, published in the journal Nature Astronomy, marks the first detection of a molecular cloud using far ultraviolet emissions of molecular hydrogen. Eos, which is composed primarily of hydrogen, presents unique opportunities for studying the interstellar medium and the processes of star formation. We discuss the implications of this discovery and how it could reshape our understanding of molecular clouds across the galaxy.Jupiter's Polar Cyclones Under the MicroscopeNext, we delve into the latest revelations from NASA's Juno mission, which is providing new insights into Jupiter's ferocious polar cyclones and the volcanic activity on its moon Io. With fresh observations, scientists are uncovering the dynamics of Jupiter's atmosphere and the subsurface temperature profile of Io, shedding light on the gas giant's extreme weather patterns and the moon's geological activity.Out of Control Russian SpacecraftFinally, we discuss the impending re-entry of the Venera 8 spacecraft, a remnant of the Soviet era, which is expected to crash back to Earth on May 10. Launched in 1972, this spacecraft has been tumbling in low Earth orbit for over five decades. We examine the risks associated with its uncontrolled descent and the potential impact it may have upon re-entry.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Astronomyhttps://www.nature.com/natureastronomy/NASA Juno Missionhttps://www.nasa.gov/mission_pages/juno/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space Time Series 28, episode 54 for broadcast on the 5th May, 202500:48 Astronomers have discovered a vast invisible molecular, gas and dust cloud near Earth12:40 Two key experiments are needed to help us understand the origin of Jupiter15:42 A failed Soviet spacecraft designed to land on Venus is about to crash on Earth19:00 New study claims people who use cannabis have higher risk of heart attack21:12 New study claims ghost lanterns in South Carolina may be caused by earthquakes

Something really weird happened out in space, and astronomers are totally baffled. A strange cosmic explosion lit up the sky, and it might be a super-rare event where everything lined up perfectly — or it could be something completely new that no one's ever seen before! It's called EP240408a, and it was first spotted by the Einstein Probe, an X-ray space telescope, on April 8, 2024. At first, it looked like your typical gamma-ray burst, which usually blasts out insanely bright X-rays. But the more scientists looked, the more things didn't add up. Now everyone's wondering if we just witnessed something brand new in the universe! Credit: CC BY-SA 4.0 https://creativecommons.org/licenses/...

I'm Rob, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. We'll start by talking about this month's big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.    5th – ETA AQUARID METEOR SHOWER – Around 10-20 meteors per hour if we're lucky, the Eta Aquarids are a minor shower that favors those in the southern hemisphere.  The best time this year is after midnight (when the Moon sets) and before dawn. Just remember each meteor is a piece of debris left over from Halley's comet, and we're crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. You never know when you'll see something awesome! Some advice for watching:  Find a dark location and lie down in a reclining chair or something that insulates you from the ground. Check the weather to see if the skies will be clear  Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.     Naked-eye PLANETS Sunset: Jupiter - About 30˚ up the sky in the W after sunset, above Taurus' head, in between its horns, setting around 11pm.  Later in the month, Jupiter is lower in the sky and sets around sunset.   Mars - Almost straight above us after sunset, but toward the SW, between Gemini and Leo (in Cancer), setting by 2am. Throughout the month, Mars will move away from Cancer and toward Leo, a little lower in the sky, setting around 1am.   Music was produced by Deep Sky Dude and used with permission.    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!

The universe can be frustrating. Roughly two-thirds of everything in the universe appears to consist of dark energy. Despite decades of study, though, scientists haven’t been able to explain what dark energy is. Astronomers discovered dark energy by studying a type of supernova – exploding stars. The supernovas brighten and fade in a predictable way. That allows astronomers to measure their distance and their motion away from us. Stars that are farther were moving away faster than expected. That suggested that something was causing the universe to expand faster over time: dark energy. But a recent study said that dark energy might not exist. Instead, the researchers proposed a new model to explain what we see, called timescape. The model notes that matter clumps together in clusters of galaxies, with huge “voids” between them. Time passes more slowly in the presence of stronger gravity – like that exerted in the denser regions. So the voids, with less gravity, could be billions of years older than the clusters – creating “bubbles” of spacetime. If that’s correct, then it would be tough to know just when the supernovas in different parts of the universe exploded. And that makes it tough to know how fast they’re moving away from us. So the study says we don’t need dark energy to explain what we see in the universe. But there’s still a lot of work to be done to understand dark energy – including whether it even exists.

Despite having rivers of methane and ethane, a new study published in the Journal of Geophysical Research Planets reveals that Titan is largely devoid of these geological features, raising intriguing questions about its unique processes and history. We discuss the implications of this finding and what it means for our understanding of Titan's climate and geological past.Volcanic History of MarsNext, we explore groundbreaking research from NASA's Perseverance rover, which has uncovered a diverse array of iron-rich volcanic rocks in Jezero Crater. This study, reported in Science Advances, provides fresh insights into Mars's geological history and its potential to have supported ancient life. The findings reveal complex volcanic processes that may have occurred on the Red Planet, enhancing our understanding of its habitability.Rare Earth Metals in Exoplanet AtmosphereFinally, we celebrate the discovery of rare Earth metals in the atmosphere of Kelt 9b, one of the hottest known exoplanets. Astronomers have detected vaporized elements such as sodium, magnesium, and the rare Earth metals scandium and yttrium, marking a significant milestone in exoplanet research. This discovery opens new avenues for understanding the atmospheres of distant worlds and their unique compositions.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of Geophysical Research Planetshttps://agupubs.onlinelibrary.wiley.com/journal/21699356Science Advanceshttps://www.science.org/journal/sciadvAstronomy and Astrophysicshttps://www.aanda.org/NASAhttps://www.nasa.gov/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 52 for broadcast on 30 April 202500:46 Scientists are looking for Titan's missing river deltas06:02 NASA's Mars Perseverance Rover is analyzing Martian volcanic rocks10:17 Astronomers have discovered rare Earth metals in the atmosphere of a hot exoplanet17:58 People who were conceived during colder seasons store fat differently, study finds20:25 YouTube is celebrating its 20th birthday with some interesting stats22:16 Google to launch Android 16 three or four months earlier than Apple's iOS

Until about 30 years ago, Jupiter was the king of the planets – bigger and heavier than any other known planet. Today, it’s not even in the top 500. It’s still the giant of our own solar system – it’s more massive than all the other planets and moons combined. But hundreds of planets in other star systems outrank it. The total number of confirmed exo-planets is up to about 6,000. They range from chunks of rock about as massive as the Moon to super-planets up to about 80 times Jupiter’s mass. Such giants are much easier to find than smaller worlds. Astronomers find most exoplanets in a couple of ways. One is to watch as a star fades a bit as a planet passes in front of it. Larger planets block more starlight, producing a bigger dip. The other way is to measure a tiny shift in a star’s light caused by the gravitational pull of an orbiting planet. Heavier planets exert a stronger pull, making them easier to find. Many of the “super Jupiters” are especially close to their parent stars. So these are the easiest planets to find. Over the years, though, the list of such planets in more-distant orbits has grown as well – bumping Jupiter farther from his throne as “king” of the planets. Jupiter is still a giant presence in our sky. It looks like a brilliant star. And it’s close to the Moon the next couple of nights – to the upper left of the Moon tonight, and a little closer below the Moon tomorrow night. Script by Damond Benningfield

The most amazing object visible through a small telescope doesn’t look all that remarkable. In fact, it looks like a faint star. Yet that point of light packs the power of 10 trillion Suns – the power of a quasar. 3C 273 is the first quasar ever discovered. When astronomers first saw it, they thought it was just another star. It looks like a star, and its main ingredient is like a star’s as well. But when they measured its distance, they were astonished: 3C 273 was two and a half billion light-years away. That meant it couldn’t be a star at all. Instead, they classified it as a quasi-stellar object – a quasar. Astronomers eventually figured out that it’s powered by a black hole at the heart of a giant galaxy. The black hole is about 900 million times the mass of the Sun. Its enormous gravity pulls in huge amounts of gas and dust, and maybe some stars. That material forms a spinning disk around the black hole. The disk is heated to millions of degrees, so it shines brilliantly – bright enough to see from two and a half billion light-years away. 3C 273 is in Virgo. The constellation’s brightest star, Spica, is low in the southeast at nightfall. The quasar stands high above it, about a third of the way up the sky. Despite its great power, it’s too faint to see with the eye alone. But a telescope reveals this deceptive wonder – a monster masquerading as a star. Script by Damond Benningfield

A tight pair of stars got a lot tighter a few years ago. The stars merged, forming a single star. And it’s still settling into its new configuration. V1309 Scorpii produced a brilliant outburst in 2008. At first, it was classified as a classical nova. Such an eruption occurs when a small dead star pulls gas from a close companion. When enough gas piles up, it causes a nuclear explosion. Over the months after V1309 erupted, though, it became clear that something else had happened. The two stars had merged, forming a rare beast called a red nova. The merger produced a brilliant flash, and expelled lots of gas and dust at half a million miles per hour. Continued study showed that the original stars were quite different. One was about half again as massive as the Sun, while the other was just half of the Sun’s mass. Since the outburst, the system has gotten fainter and bluer. That could mean it’s becoming a blue straggler – a star that looks younger and brighter as the result of a merger. Or it could be headed toward a phase known as a planetary nebula – expelling its outer layers, leaving behind only a dead core. Astronomers continue to watch to see what happens. V1309 is in Scorpius, which is low in the southern sky at dawn. Tomorrow, it’s just a tick to the lower left of the Moon. But it’s thousands of light-years away, so it’s too faint to see without a telescope. Script by Damond Benningfield

Episode 298 Big news has just broken - astronomers claim they've detected the strongest evidence for alien life yet. The news has got the world's media fired up with excitement - but is this really a “revolutionary moment”? Astronomers studying the atmosphere of a distant planet called K2-18b say they have detected a molecule called DMS that is only produced on Earth by living organisms, so it's thought life might be producing it there too. Hear from the lead researcher on this project, Nikku Madhusudhan of the University of Cambridge, who says “these are the first hints of an alien world that is possibly inhabited”. But even if this biosignature detection is confirmed, would it be the slam dunk everyone thinks it is? In this episode, Alex Wilkins and Rowan Hooper offer a bit of balance to the discussion and explore how far this is from definitive evidence of alien life. We also hear the views of Laura Kreidberg, managing director of the Max Planck Institute for Astronomy.

The Sun is an unusual star in several ways. It’s the only star known to support life. It’s in the top 10 percent of the most-massive stars in the galaxy. And it’s in the minority in another way: it moves through the galaxy alone. Like all stars, the Sun probably was born in a cluster – a group of hundreds or thousands of stars. But the Sun’s birth cluster fell apart, with the stars going their own ways. Most stars hang on to one or more of their siblings. Most of them form binaries – two stars bound by their gravity. Others form systems of three stars or more – all the way up to seven. The heavier a star, the more likely it is to have companions. For stars like the Sun, the odds are about 50-50. The Sun has no companions today. But it could have in the distant past. In its crowded nursery, close encounters with other stars could have pulled the Sun and any possible companions away from each other. Astronomers haven’t found any long-lost binary “twin” of the Sun. But they have found some stars that could have been born in the same cluster. A great example is HD 162826. Astronomers at McDonald Observatory found that its composition and motion are very close matches to the Sun’s. HD 162826 rises above Vega, the brightest star of Lyra. They’re in the northeast in late evening. But you need binoculars to see this likely sibling to the Sun. More about binaries tomorrow. Script by Damond Benningfield

Dune. Star Wars. Alien. Science fiction movies love alien worlds, and so do we. But how do scientists find planets outside our solar system in real life? One way is by looking for the stars that wiggle. Historically, astronomers have measured those wiggles via the Doppler method, carefully analyzing how the star's light shifts. Thanks to new data from the GAIA telescope, scientists have a much better picture of distant stars' wiggles — and the exoplanets that cause them.Want to hear more about exoplanet discoveries?

Ulugh Beg was a poor politician and warrior. Just a year after becoming leader of the central Asian kingdom of Transoxiana, he was deposed by his son – then beheaded. Yet he was one of the top scientists and educators of his time. He built a school and observatory at the capital city of Samarkand. Astronomers there made highly accurate measurements of the heavens – two centuries before the invention of the telescope. Construction of the observatory began in 1420, and was completed a few years later. The complex consisted of a tall, round building that housed a variety of instruments. The main one was a quadrant – a quarter of a circle. It was the largest one ever built – 130 feet from center to rim. Its base was carved into a hillside, making it highly stable. And it was aligned with the meridian – the north-south line that passes directly overhead. Astronomers used precise markings on the instrument to measure the positions of the Moon, Sun, planets, and stars. From those observations, they determined the length of a year to within a minute of the modern value. They calculated the tilt of Earth’s axis.
