Walkabout the Galaxy
Transiting Exoplanet Survey Satellite, dark matter, TESS, space telescopes
Astrophysics and Astronomy | Physics
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.
No, not Bucky's balls: these aren't Buckminster Fuller's family jewels, but they are part of his legacy, just not genetic. Buckyballs, or Buckminsterfullerene, is good old fashioned Carbon. And while C60 Carbon atoms are arranged in hexagons, and not the triangles of Bucky's geodesic dome homes, take some buckyballs with you on your next walk about the galaxy, or if you can't get your hands on the real stuff, bring a soccer ball with the same arrangement of corners as the atoms in a buckyball, and bounce your way about the galaxy. Buckyballs, making chemistry fun, or at least funny, and proud sponsor of Walkabout the Galaxy.
