At first glance, Bunburra Rockhole looks like the other Vesta meteorites, but its Oxygen isotope abundances are peculiar and unique. In addition to exploring this meteoritical mystery, in this episode the Astroquarks take a look at the aging of galaxies, and how their star formation rate is controlled by the beast at the center of their galaxy, namely a supermassive black hole. <\/p>\n<p><a href=\"https:\/\/itunes.apple.com\/us\/podcast\/walkabout-the-galaxy\/id867430953\">View on iTunes<\/a><\/p>\n<p><a href=\"https:\/\/player.fm\/series\/walkabout-the-galaxy\">View on Player FM<\/a><\/p>\n<p><a href=\"https:\/\/play.google.com\/music\/m\/Inbxmj4wrp6eg2ch3qpgqcpslzy?t=Walkabout_the_Galaxy\">View on Google Play<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the largest asteroids, 4 Vesta, has a unique spectrum that matches some meteorites that is a clue that those meteorites are actually chunks knocked off of Vesta at some point.
