They are the brightest beacons in the universe, blazing across space with the intrinsic brightness of one trillion suns. Yet the objects are not vast galaxies, but they appear as pinpoint sources in the biggest telescopes of today — hence the term "quasar" for quasi-stellar object. Discovered in the 1960s, it took more than two decades of research to come to the conclusion that quasars are produced by the gusher of energy coming from over-fed supermassive black holes inside the cores of very distant galaxies. And, most quasars bloomed into a brief existence 12 billion years ago. Join astronomers during the live Hubble Hangout discussion at 3:00 pm EDT on Thurs., June 18, to learn even more about quasars and the Hubble Space Telescope. To join, visit http://hbbl.us/z7F .
