We think of aurora as an atmospheric phenomenon, but what happens when high energy particles from the Sun directly impact a planetary surface? Mercury reveals another cool planetary twist with auroral-like emission from its surface. Meanwhile, Jim and and Josh are gobsmacked by the old news of a big gravitational potential hump in the Indian ocean caused by upwelling of low-density magma far below. Catch up on all the cool space news with the astroquarks.

X-Rays from Mercury and a Different Kind of Gravitational Hole

Nature has provided us with exquisitely accurate clocks in the form of pulsars, those rapidly rotating neutron stars whose beams of radiation act like high-powered lighthouses across the galaxy. We discuss the amazing discovery of a deep, low, rumble of gravitational waves across the universe by analyzing the periods of 79 of those pulsar lighthouses. Closer to home, there's evidence for a major climate shift on Mars 400,000 years ago that lines up with changes in Mars's spin. Check it all out on this episode of WtG, with wave trivia and space news too.

The Rumble in the Universe

Top quark has a field day in this episode with a model for fuzzy dark matter, new data that could shed light on dark energy, and a cool x-ray echo from the supermassive black hole at the heart of our galaxy. Closer to home, we take a look at how JWST is helping us determine if exoplanets have comfortable greenhouse effect atmospheres. Plus, we have a surprising spaceship trivia question and a space travel stumper.

All Things Dark: Matter, Energy, and More

New analysis of radioisotopes of meteorites and the Earth suggest the Earth formed in only a few million years via a process called pebble accretion. This may mean the Earth’s water was incorporated early and gradually rather than through late impacts. Recent determinations of the historical length of the Earth’s day suggest it stalled out at 19 hours for a cool billion years, and we still have a ways to go to get to 25 hours when we can all sleep in. Find out about the Earth’s history, supermassive black hole mergers, and syzygy trivia.

Earth's Pebble Accretion and the Boring Billion

There’s a bright supernova in a nearby galaxy, and a very distant supernova made brighter by the beauty of gravitational lensing. In another galaxy, a gargantuan black hole is revealed to be orbited by another supermassive black hole, resulting in a gamma ray flares as it rips through the main black hole’s accretion disk. Closer to home, we learn about new asteroid missions and a rapidly warming planet (hint: it’s ours). Plus: Harrison Ford and Leonard Nimoy trivia!

Lefty astroquark Jim Cooney leads us on an exploration of what it means for the universe to have chirality. In other words, is there a break in parity in the way galaxies are distributed, or would the universe look the same if we saw its mirror image? The answer and its possible explanation are fascinating. And Josh gets to once again talk about one of his favorite topics, Saturn’s rings, and new results on their age.

Is the Universe Left or Right-Handed?

We take a deep dive into the origin of Mars’s moons and whether they are chips off the old block. There’s no research to explain the mystery of why Mars and the rest of the planets are even here after billions of years, when the solar system seems to be inherently unstable. And astronomers may have caught a star in the act of gobbling up a planet in the first stages of the star’s death throes. Catch up on these scary things that can happen to a planet, space news, and Top quark trivia.

Scary Things That Can Happen To Planets

We explore the strange ring system of dwarf planet Quaoar, and discuss a new study that suggests that Uranus's four largest moons (which aren't really very large!) may have subsurface salty oceans. In the astrophysical realm, black holes may have emerged from the chaotic soup of energy during the inflation era when the universe was not even minutes old. Add to that some nerdy computer trivia and you've got yourself another episode of Walkabout the Galaxy!

Crazy Rings, Watery Moons, and Ancient Black Holes

New calculations show how large impacts onto Mars may have boosted its greenhouse effect, helping explain how it was warm enough for all those rivers and lakes billions of years ago. If that explains Mars' early warm climate, it could be bad news for potential for life there. Futher from home, dust has been observed star forming regions in the Small Magellanic Cloud where the abundance of planet-building raw materials is low. Check out these stories, space news, and special top quark trivia.

Walkabout the Galaxy

Lurking out there beyond the orbit of the Moon is a sneaky little asteroid that is stalking the Earth, meandering around and pretending not to be paying attention. But you can't fool the fools on Walkabout the Galaxy. Jim Cooney joins Josh and Addie as we spill the beans on Earth's tiny not-quite-a-moon companion and review the latest discovery of black hole mergers by the LIGO gravitational wave observatory.

The astroquarks welcome noted science blogger and author Dr. Ethan Siegel whose new book Treknology takes a look at the intersection of science and science fiction. While you may already have a tablet computer, warp drive is probably still a few years away. But Elon Musk may be sending missions to the moon in less time than it takes the U.S.S. Enterprise to complete its 5-year mission (so, less than 5 years, get it?). Tune in for the latest news on exploration of the solar system as well as a look back to some classic Trek-nology with Dr. Ethan Siegel on this episode of Walkabout the Galaxy.

Not content with being the self-proclaimed "Pluto Killer", CalTech professor Mike Brown has now co-authored a paper hypothesizing the existence of, in his own words, "the most planet-y of planets" or "Planet 9", in the far outer reaches of our solar system. We get it: you hate Pluto! But personal planetary battles aside, this is an interesting bit of dynamical detective work in which lead author Konstantin Batygin and Brown argue that a roughly Neptune-sized planet several hundred times further from the Sun than the Earth is needed to explain the peculiar configuration of a dozen or so objects in the Kuiper Belt. Jim Cooney joins Josh and Addie to talk about Planet 9. If it's the most planet-y of planets, let's come up with a new name for whatever the Earth is.

While we stick by our longstanding advice never to enter a black hole, Jim Cooney and Zoe Landsman join Josh and Addie in this episode to discuss new findings that radiation emitted by black holes through quantum effects may carry information about the stuff the black hole gobbled up. Also, the rate of expansion of the universe may be a bit faster than previously thought. File this under "things I don't need to worry about before I run my errands."

The Great Black Hole Escape

An instrument on the International Space Station that can help us understand more about antimatter is getting an upgrade, and we review that old sci-fi staple: the wormhole. Somehow we manage to do this without talking about Star Trek (mostly), but we have nerd news and space updates together with trivia and a new discovery about some of the many moons in our solar system.

Disappointed that we don't have jetpacks and flying cars? Dr. Amanda Hendrix joins the Astroquarks to suggest an alternative: colonize Saturn's moon Titan, where a thick atmosphere and weak gravity mean we could all just fly like birds! Really! But, wait, there's more! Tune in to this episode of Walkabout for discussions of nearby moons and planets to colonize, space trivia and more.

One of these rocks is not like the other. One is a meteorite, and one is an asteroid, and we know that meteorites come from asteroids. So how come they look so different? The astroquarks discuss new research into ancient meteorites that shows how the tumultuous history of the asteroid belt is to blame. Plus charm quark Addie Dove points out that one rock is on the ground and one isn't, so there's a pretty big different right there. Strange quark Josh Colwell gets very strange with the sponsor message, and top quark Jim Cooney tells us that if you'd like to age about 1 second slower than everyone else you just have to move to the center of the Earth's core. In other words, just another episode of Walkabout the Galaxy.

A Space Odyssey

Venus continues its record-setting warm streak now at over 1 billion years and counting, while the Earth just set its own modest record for the hottest year in the last 150 for the third record-setting year in a row. We've got a lot of work to do if we want to catch up with Venus. Speaking of Venus, something weird happened in its atmosphere that's probably the result of a gravity wave, not to be confused with gravitational waves which are a different beast altogether. Let the astroquarks take you on a journey from Venus to distant galaxies, and from greenhouse warming to non-Newtonian dynamics in this episode of Walkabout the Galaxy.

How exactly (and why) does a spacecraft get a "gravitational assist" from a planet en route to another planet? Where does that energy come from? The Astroquarks take a look at gravity assists and the OSIRIS-REx mission to grab some bits of a Near-Earth Asteroid and bring them back to Earth. Plus, the field of gravitational wave astronomy expanded now with the detection of a new black hole collision by two separate gravitational wave observatories. It's a weighty episode.

The Babiest Galaxy

A long time ago in a galaxy far, far away, two big black holes (no jokes, please) collided with each other releasing a ginormous amount of energy that has propagated across the universe as the tiniest stretching and jiggling of space itself. Jim Cooney joins Josh and Addie to talk about the first direct detection of the waving of space-time (in other words, gravitational waves).

Planet 9, also known as Egotron in honor of its supporters, has never been seen. A new statistical analysis of a deep sky survey suggests that's because it doesn't exist. The object's existence has been proposed to explain an apparent clustering of the orbits of some objects that have the charming quality of actually having been directly observed. The astroquarks discuss the arguments for Egotron and how statistics and observation bias play into all this. Speaking of statistics and planets, Kepler's list of planet candidates keeps growing. Hear about the latest discoveries, nerd news, space trivia and more on this episode of Walkabout the Galaxy.

While terrestrial matters were frequently dark and depressing, 2017 was a banner year for the cosmos, or at least for our understanding of it. From Cassini's Grand Finale to LIGO's detection of neutron stars colliding, the astroquarks review the highlights of the year and a new story about a very old black hole from the dawn of the universe. A supermassive black hole formed before the universe was a billion years old, suggesting galaxy formation was off to a robust and early start. Join Josh, Addie and Jim for all that, nerd news and space trivia to wrap up 2017.

A long time ago in a galaxy far, far away, a little neutrino left a very large black hole headed straight for a point in space that would be occupied by the Ice Cube neutrino observatory at the Earth's south pole just in time to detect it! This is the story of that neutrino, Scrabble(TM) competitions, neutrino trivia, and a very embarrassing sponsor message. We're all very sorry about that sponsor message, but they paid, so we honored the contract, okay?!
