Walkabout the Galaxy

Strange and Top are at it again with a deep dive on the physics, psychology, and philosophy of the big questions: is there technologically advanced life out there in the galaxy, and if so, we will ever know? Will we make it out of the solar system, and if so, what would that look like? Join us for all that and a physics question disguized as a trivia question.

Supermassive have such voracious appetites that they create an energetic mess when eating which has a tendency to shoot their food off at very high speeds. New observations show the second course for these monsters as material falls back into them. A rocky exoplanet in the habitable zone has a confirmed atmosphere, checking another box for finding worlds that may have life. J...

Quasars, the energetic engines driven by the voracious appetite of supermassive black holes, have been observed in the very early universe, upending ideas about how long it took to form these behemoths in the first place. New results on a peculiar object tagging along around the Sun with the Earth casts doubt on its origin as a possible fragment of the Moon. And the climate t...

The astroquarks examine the oft-asked question of why the Moon sometimes looks huge and other times, not so much, and we take a look at the cool mission to grapple and boost the NASA Swift space telescope into a higher orbit. Plus, new observations reveal that the sky is much brighter at radio wavelengths than previously assumed, teaching us something about the population of ...

OG Top Quark Tracy Becker joins us with an update on water plumes from Jupiter's moon Europa, plus intriguing new data of interstellar comet 3I shows it is even older than we thought, with an age approaching that of the Milky Way galaxy itself. A new field of tektites has been discovered, pointing to a previously unknown major impact on the Earth. Join us for all this, space ...
