An irreverent and informative tour of the latest, greatest and most interesting discoveries in astronomy.
Gravitational waves and light combine to reveal what is suspected to be a superkilonova which is much cooler than the name suggests. Cool in...
Gravitational Wave observatory LIGO has seen a signature that looks like the merger of primordial (pre-stellar, big bang (not big band!) era...
Supermassive black holes can be terrible neighbors. New research shows that their powerful jets of charged particles can shut down star form...
The Earth spent some crazy amounts of time (tens of millions of years) completely frozen over. And not, in the grand scheme of things, all t...
There's always been a fuzzy line between asteroids and comets, and new observations of asteroids in the vicinity of Jupiter provide a hint t...
Scientists head to the volcanic fields of Iceland to test instruments for the VERITAS mission to Venus, Artemis II is ready for its historic...
The amazing discoveries from the Vera C. Rubin Observatory have already started, and the astroquarks take a look at some close to home. Aste...
The Parker Solar Probe flies through the Sun's corona, MAVEN has gone silent, and new data shed light on the origins of cosmic rays. JWST's...
We explore the dining and drinking choices for astronauts, complex chemicals discovered in asteroid samples, and untangling the web of scars...
There's a new funky proposal for small black holes in the early universe, and another potential dark matter candidate. Learn about cannibal...
The story behind this investigation is almost more cool than the discovery itself. Microlayers of sediments in Mars' Gale Crater, observed b...
Things would be a lot simpler and a lot less interesting if charge parity existed in the universe, but there would be no one to appreciate t...
The astroquarks are joined by Jeffrey Kluger, editor at large at Time Magazine and author of 13 books including Apollo 13 and the new book o...
These rings aren't around Uranus, they're somewhere even more odd. We discuss the mysterious and changing ring system around the Centaur obj...
Adaptive optics techniques get applied to the mirrors in the LIGO gravitational wave observatory, promising a five-fold or greater improveme...
We take a look the Cheyava Falls rock on Mars, or rather the Perseverance rover took a look at it, and we discuss what it saw which were som...
An interstellar interloper may have been a chip off the old block, where the old block was a Pluto-like planet around another star, and the...
That's no error, this is episode 404, recorded in front of a live audience at DragonCon 2025 with special guest Trina Ray, Deputy Science Ma...
There is so much going on in the universe it's hard to keep track. That's why we have not one but two top astroquarks on this episode to cov...
There's more abundant and accessible water ice on Mars, ready for us to scoop it up, heat it up, and eat it up. And in the distant recesses...
We discuss the largest black hole merger observed to date, between two black holes that are in the so-called forbidden mass range. They must...
The astroquarks celebrate 400 episodes with a special sponsor, a special stumper, and a special interstellar comet making its way through ou...
The Vera C. Rubin Observatory has started making observations with the world's largest optical detector boasting over 3 billion pixels at th...
We're all about the weather on this episode, with a new study showing that even relatively distant supernova may have affected the Earth's c...
Original top quark Tracy Becker is back to bring us up to speed Europa Clipper's flyby of Mars, and we learn about a new way for planetary c...
A major update to the predicted end of the universe has it coming much earlier than previously anticipated. However, we still have plenty of...
We get lucky and catch a rogue supermassive black hole in the act of slurping up a star as it meanders through a distant galaxy. Closer to h...
The asteroid Vesta may be a fragment of a much larger protoplanet, and astronomers examine old data to discover a large molecular cloud lurk...
NASA's Lucy mission had a picture perfect encounter with the asteroid Donaldjohanson on its way to the first ever flybys of Trojan asteroids...
The astroquarks discover hot takes and explore the nature of ice, the origin of Earth's water, and the trouble with the singularities at the...
Venus's extra-thick crust may be extra chewy, allowing convection to occur and helping power volcanoes into the current era. New observation...
A survey of nearby stars establishes the rate of supernovas in our general neighborhood. Evidence indicates we had nearby stellar explosions...
If there are Hycean worlds and if they have a certain kind of microbial life and if there is enough of it, JWST might be able to see the che...
There are exciting new observations from recent lunar missions, a possible chunk of the Moon keeping us company, and an intriguing observati...
We take a look at the formation and structure of the Oort cloud of comets which is spherical at large distances but has a spiral structure i...
Lunar exploration continues to accelerate, and there's a new longest "structure" in the universe. Quipu is a quasi-alignment of clusters of...
The more measurements we make of the expansion of the universe, the more it seems as though Hubble Tension is not a problem with our data bu...
Juno reveals a surprise about the interior of Jupiter's volcanic moon Io, and the OG young variable star T Tauri is getting ready to fade fr...
The discoveries from the James Webb Space Telescope keep coming. After showing that galaxies formed far earlier than we thought, we now have...
Pluto and its largest moon, Charon, orbit each other with gazes lovingly fixed on each other, held in place by a romantic tidal attraction....
We kick off 2025 with oddities from quasi particles, to cosmic rays, to the moons of Pluto. What has mass when it moves in one direction and...
We know about extinct comets and active asteroids, but now we've got something in between: dark comets, whose orbits indicate cometary activ...
Top quark Jim Cooney explains why making big blobs is hard and how new observations are helping us understand how the universe made big imme...
It's a good news bad news story with the detection of the neutrino fog. This signal from solar neutrinos may confound our search for certain...
If you're speaking English, not Latin, do you really have to say "supernovae" instead of "supernovas"? Also, they are, in some sense, create...
New observations contradict earlier studies about the possibility of another belt of comets orbiting the Sun twice as far away as Pluto. We'...
Join Strange and Down quarks for a close look at Trojan asteroids, the forgotten asteroids of the solar system. NASA's Lucy mission is en ro...
We get a tour of our place in the grand cosmological scheme of things with new mapping of the local Basin of Attraction. Spoiler: also Jim's...
Original Top Quark Dr. Tracy Becker returns to her old stomping grounds to hang with the Walkabout crew and send Europa Clipper on its way t...
We've got mini black holes as potential dark matter candidates and monstrous black holes spewing jets to cosmological scales. Who better tha...
