Walkabout the Galaxy

In this special Elizabethan episode of Walkabout, we check out the tired, battered, and bruised asteroid Pallas, one of the largest in the asteroid belt, and discuss why its neighbors beat up on it so much. We also take a peek at a new discovery about antimatter and an exotic quirk of quantum mechanics that also lives in the antimatter realm, catch up on space news, time travel shows, and much more.

We have an interesting new clue about what causes the ridiculously power phenomena known as Fast Radio Bursts (or at least about what doesn't cause them!), and we are joined by astroquark emerita Tracy Becker to tell us about the discovery of a baby moon around a near-Earth asteroid from the Arecibo Observatory. We also have Earth news and Space news and an energy round of trivia. Toss in a little matter-antimatter and it's another episode of Walkabout the Galaxy.

The astroquarks discover their new favorite thing in the universe. They'll tell you all about it and why we all have to hope it's a real thing. Also learn about ridiculous mathematical functions, the latest space news, and a little gravitational blippity-bloop for good measure.

Would you rather go ice fishing on an alien moon or bungee jumping on Mars? Either way, you definitely want to hear about the mysterious way matter twists spacetime with another confirmation of Einstein's general theory of relativity involving a white dwarf and a pulsar. Join the astroquarks for all that plus the discovery of the nearest exoplanet, solar system trivia, and all the latest space and nerd news.

Volcanoes on ancient Earth and not-so-ancient Venus are the main topics for the astroquarks, with planetary trivia, and a giant gassy wave moving through the Milky Way. Catch up on all the different types of numbers, from imaginary to prime, and all the space news  and climate updates on this episode of Walkabout the Galaxy. Check out YouTube for the gas-wave shimmy.

The astroquarks explore our origins with from the ancient fossil Lucy to the upcoming asteroid mission of the same name. They then head for the stars, including a nearby one with a potentially habitable planet, and re-examine the case for dark energy. You're not going to want to miss this one, for the science, the trivia, and a special sponsor message.

The title has nothing to do with the episode except what could be more fundamental than simply measuring how far away something is? The astroquarks tackle this deceptively complex question on cosmological scales as well as the origins of meteor showers and archeoastronomy of ancient aurorae.
