I Think I Stepped in Some Dark Matter

What do Annihilation, Buckyballs, the Transiting Exoplanet Survey Satellite and an itsy-bitsy galaxy have in common? They're all topics for the latest walkabout the galaxy with the astroquarks. A small galaxy has been observed with essentially no dark matter (most are mostly made of the dark stuff). Paradoxically, this is very strong evidence for the existence of dark matter. Speaking of things that are hard to see, we'll also check in on TESS, the next space telescope designed to discover lots of Earth-y exoplanets. Join Josh, Addie, and Jim for another whimsical jaunt through the latest news in astronomy and a peak at science fiction.
