https://spacescoop.org/en/scoops/2605/story-of-suns-road-trip-through-the-milky-way-with-friends/ Did you know that our Sun and its many, uh, childhood friends were all born at a place much closer to the center of our Galaxy? Over the years, our Sun and its friends have been on sort of a speedy galactic tour traveling a distance of almost 10,000 light-years from the center of the Milky Way. But traveling much farther than that on a long curved trajectory! Astronomers call this the 'mass migration' of stars. Kind of like a flock of migrating birds.    How and when did these stellar siblings migrate to where they are now? To find out, a team of astronomers did some galactic archaeology, tracing the history of stars in our Galaxy. Using data from ESA's Gaia telescope, the team found almost 6,600 stars just like our Sun. The astronomers aptly call these stars the 'solar twins.'    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!

Astronomers using the James Webb Space Telescope have observed clouds on a hot gas giant exoplanet called WASP-94A b, some 700 light-years away. But these clouds aren't your usual wisps of water vapor—they're vaporized sand. Astronomer David Sing joins Host Flora Lichtman to describe the planetary weather, and how the researchers were able to observe it.  Then, ecologist Elske Tielens joins Flora to describe how ecologists using weather radar data counted the insects aloft in U.S. skies: around 100 trillion of them on an average summer day. Guests: Dr. David Sing is a Bloomberg Distinguished Professor of Earth and Planetary Sciences at Johns Hopkins University. Dr. Elske Tielens is an ecologist with the Swiss Federal Institute for Forest, Snow and Landscape Research.

This is a rebroadcast of one of our favorite episodes from the past! It's a scientific controversy of planetary proportions! Is Pluto a planet, or not? You decide, after we present two sides of an epic astronomy argument. Back in 2006, the International Astronomer's Union voted on a definition of the word “planet” that excluded Pluto and other newly dubbed “dwarf planets” from planethood status. Astronomers - and everybody else - quickly chose sides. We dive deep into the debate and learn that Pluto's not the only Space Object Formerly Known As A Planet. Then we'll ask you to weigh in with your opinion, and see if you can find “consensus” on what should be called a planet. Featuring planetary astronomer Kirby Runyon. We have a present for your birthday!! We'll be doing birthday shoutouts for our Patreon members, beginning next month. Want to hear a message on the podcast just for your special day?

It was only a few years ago that excited supporters of the big bang theory for the origin of the universe announced that their theory had apparently been proven. Now their unverified conclusions are being seriously questioned on several fronts.Even as it was being announced that the big bang theory was proven, verification was being made on other results showing that the big bang theory is probably wrong. William G. Tifft of the University of Arizona had been looking at lists of red shifts from distant galaxies. On a graph, he plotted the red shifts corrected for the effects of the earth's motion. If the red shifts from these objects are the result of their speeding away from earth, their red shifts should be evenly spread over the known range of shifts. Tifft found that they're not. The red shifts are clumped into patterns. The intervals are about 72 kilometers per second, with some half that value and some one-third of that value. Astronomers from the Royal Observatory in Edinburgh verified his results.A second study by Tifft has shown that galaxy red shifts measured from earth have changed in just a few years! This change is completely unexpected by proponents of the big bang theory. The change is large enough that Tifft expects to be able to test the rate at which these changes take place within only a few years! One suggestion is that red shifts may be some sort of decay phenomenon rather than expansion of the universe.How could human beings expect to understand a universe created by the Author of Scripture when they reject Scripture itself?Isaiah 55:8"For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.”Prayer: I thank You, dear Lord, for the revelation of Your Word of salvation in Scripture. I pray that I may never presume to understand something before I know and believe what You have said about it in Your inerrant Word.

The 100-year search for dark matter began in 1922 with Dutch astronomer Jacobus Kapteyn, who was the first to use the term "dark matter" in a scientific paper. Kapteyn realized that the gravity of unseen matter must govern the motions of stars. His student, Jan Oort, later expanded on this by studying the vertical "up and down" motions of stars in the Milky Way to estimate the mass in the galactic plane. Fritz Zwicky provided a major breakthrough by observing the redshift of galaxies in the Coma cluster, concluding they moved too fast for visible mass to hold them together. Zwicky termed this missing mass "Dunkle Materie." These early pioneers identified a gravitational discrepancy—the "elephant in the universe"—that would define modern cosmology as scientists began hunting for what they could not see.

Last July, space telescopes recorded an event that sounds like the plot of a “B” horror movie: Zombie Versus Vampire. Spoiler alert: the vampire won. It drained away the zombie’s life’s blood – or make that its after-life’s blood. The encounter took place in a galaxy billions of light-years from Earth. Space telescopes detected a sudden flare-up in X-rays from the galaxy’s outskirts. The region also produced several short outbursts of gamma rays, the most powerful form of energy. At their peak, each burst produced as much energy every second as the Sun will emit in a billion years. Analysis revealed a possible explanation: a medium-sized black hole devoured a white dwarf – the “corpse” of a Sun-like star. Astronomers have seen similar encounters before. But most of them involved stars that were in the prime of life, so the stars were big. A white dwarf is only about as big as Earth, which is just one percent the Sun’s diameter. So a white dwarf is compact and extremely dense. Its surface gravity is strong, so it’s not easily disrupted. In this case, though, the white dwarf buzzed a black hole about 75,000 times the mass of the Sun. The black hole’s gravity ripped apart the white dwarf in one big bite. Debris swirled around the black hole. Magnetic fields fired some of it into space at almost the speed of light, creating bursts of gamma rays. The whole thing was over in a flash – as the vampire sucked the zombie dry. Script by Damond Benningfield

A massive star in the Andromeda Galaxy might have tried to blow itself to bits, but it failed. Instead, almost the entire star collapsed to form a black hole about five times the mass of the Sun. Astronomers discovered the possible misfire while combing through observations by NeoWise, a space telescope that wrapped up its work a couple of years ago. They found an object that brightened dramatically at infrared wavelengths, which are invisible to the human eye, then slowly faded again. Earlier observations at visible wavelengths showed a supergiant star, perhaps a hundred thousand times as bright as the Sun. But as the infrared peaked and faded, the visible light faded completely – the star simply vanished. The astronomers concluded that the event was a failed supernova. The star stopped producing nuclear reactions in its core, so the core collapsed. A shockwave plowed through the star’s outer layers, blasting their gas outward. In most cases, such a shockwave creates a titanic explosion – a supernova. But this blast wasn’t powerful enough to overcome the core’s gravitational pull. So almost all the gas fell back onto the core, making it massive enough to form a black hole. A little material did escape. It formed a wide disk of gas and dust around the dying star. Energy from the star made it shine brightly in the infrared – a short flare-up that waned as the supergiant star collapsed and faded from sight. Script by Damond Benningfield

Episode 366 A Pluto-sized object in the outer solar system has shocked scientists. It's so tiny that it shouldn't have an atmosphere - but it does. Object 2002 XV93, known as a plutino, is a small rock floating about in the Kuiper belt - a doughnut-shaped region of icy objects out near Pluto. What's surprising is that many dwarf planets bigger than this object can't hold an atmosphere, so it's a mystery how this is even possible. This discovery comes as the decades-long debate about Pluto begins to bubble up again. Pluto was demoted from its planet status in 2006. But now NASA Administrator Jared Isaacman is reigniting the debate - on a controversial mission to make Pluto a planet again. So with this mysterious object and its unexpected atmosphere, plus the chance of Pluto being reinstated, do we need to change how we define planets? Is everything just a planet now?  Rowan Hooper and Penny Sarchet are joined by Jacob Aron and James Woodford to discuss the many ramifications of this new finding.

We're living through the great Space Boom and with great innovation comes a lot of whacky ideas... Astronomer and Associate Professor Michael Brown from Monash University joins me to discuss stupid things in space.  The conversation dives into some of the more bizarre and ambitious ideas circulating the space industry, from firing villains and radioactive waste in to the sun to deploying giant orbital mirrors to light up Earth's dark side. Brown breaks down why many of these concepts are far less practical than they sound. With over 15,000 satellites circling earth, Brown also examines the promises and downsides of mega-constellations like Starlink, including how they operate and the challenges they pose for astronomers and the environment. It's a fascinating and critical peek in to the intersection of innovation, risk, and imagination in the new space age.

After Greg reported his observations to the Minor Planet Center his discovery was tracked by telescopes in California, Romania, Germany, New Mexico, Arizona, Bavaria, and Japan. Astronomers used these data to calculate that Greg's discovery orbits the sun between Venus and Earth , estimate its size to be approximately twice the length of a football field, and give it the name 2026 BX4. NASA classifies it to be a Potentially Hazardous Asteroid, however, since it doesn't cross the Earth's orbit it is not an immediate impact threat. In fact it will not come as close to us as it can on its current path until February 17, 2075 when it will pass less than 6 times the moon's distance from us. Because 2026 BX4's orbit is entirely within the Earth's path about the Sun it is classified to be an Atira asteroid. These space rocks are difficult to discover and track because they are always near the Sun in the sky. 2026 BX4 could become an impact threat by gravitational interactions with Earth, Venus or another asteroid. There are also Aten asteroids which spend most of their time inside the Earth's orbit but cross it and are more of a threat than an Atira asteroid like 2026 BX4. Currently the most dangerous Aten asteroid is Apophis which will safely pass closer to us than the communication satellites on Friday February 13, 2029. Asteroid hunters will continue to discover and track both Atira and Aten asteroids to make sure none of them sneak up on our home planet from the direction of the Sun.

What did the universe look like before any stars turned on? Astronomers call that time the “dark ages,” and while they think it may be possible to see remnants of it in very low frequency radio signals, hearing those signals from Earth can be challenging.   One possibility is to put a radio telescope on the far side of the moon, where it would have periods of observation shielded from interference both from Earth and from the sun—and potentially be able to receive that dark ages signal. The LuSEE-Night mission will explore that approach. A small demonstration radio telescope is slated for launch in late 2026 to serve as a proof of concept for low frequency radio astronomy on the lunar far side. Astronomer Anže Slosar, lead scientist for LuSEE-Night, joins Host Ira Flatow to describe the telescope project and what astronomers hope to achieve by sending it to the moon.

He was a man of numbers, perhaps THE man of numbers! Nathaniel Bowditch was a math super-genius, an astrologer, a bookkeeper, a finance bro, a shipmaster, a sailor, and by any and every account, a very practical navigator. Join Sarah and Jeffrey, your favorite Salem tour guides, as they learn who exactly this son of a copper turned finance guy really is. We know him as a shipmaster and navigator, but what other innovations can we credit this math wiz with? And is his famous book “The New Practical Navigator” still in use on every US vessel today?

Astronomers love star clusters. All the stars in a cluster were born at the same time, from the same cloud of gas and dust. So any differences in the stars are the result of their evolution, which is a result of their mass. That makes it easier to learn what’s going on inside the stars. One problem, though, is identifying which stars belong to a cluster. It takes detailed measurements of motion and brightness to separate members of the cluster from stars that just happen to line up in the same direction. An example is the Coma star cluster, in Coma Berenices. The constellation is in the east at nightfall. Under dark skies, the cluster is a good target for binoculars. The cluster is about 280 light-years away. But it spans dozens of light-years, so its stars are spread out. That makes it harder to pick out its members. And it takes big telescopes to pick out its fainter stars. So despite decades of study, astronomers are still locking down the census of stars in the Coma cluster. A study about a decade ago confirmed eight small, faint members – the first of their kind known to belong to the cluster. And another study found that about a quarter of the stars in the cluster are binary or multi-star systems. These discoveries bring the total number of stars in the Coma cluster to several dozen, with a few dozen more possibilities – members of a wide-spread stellar family. More about Coma Berenices tomorrow. Script by Damond Benningfield

Astronomers have discovered one of the most chemically primitive stars ever identified — an ancient stellar relic that preserves the chemical imprint of the very first stars in the Universe. In this podcast, Dr. Ani Chiti discusses the discovery of this ancient star and what it tells us about star formation in the early Universe.    Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Dr. Anirudh Chiti is a Brinson Prize Fellow at Stanford University, interested in the formation of the first stars and galaxies, the early production of heavy elements, the early Milky Way, and local tracers of dark matter. He observes and characterizes nearby stars and galaxies that formed at early times to understand these topics, in an approach known as "Near-field Cosmology" or "Galactic Archaeology".   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!

Researchers at the Large Hadron Collider in Switzerland have announced that they discovered a new subatomic particle. Roughly four times more massive than a standard proton, this short-lived piece of matter called Ξcc⁺(Xi-cc-plus) is like an extra-heavy proton, researchers say. Physicist Hassan Jawahery joins Host Flora Lichtman to unpack how the particle was found, and what its discovery means for theoretical physics.  Then, astronomer Eric Bellm describes a new alert system that could flag potentially significant changes in the southern night sky in real time. On its first night of testing at the Rubin Observatory in Chile, the system fired off 800,000 alerts. Guests: Dr. Hassan Jawahery is a distinguished university professor at the University of Maryland and a member of the LHCb consortium.  Dr. Eric Bellm is alert product group lead for the Rubin Observatory and a research associate professor at the University of Washington.
