Quasars are among the brightest outflows of energy in the universe, with an intrinsic brightness of one trillion suns. Most quasars appear as pinpoint sources in the biggest telescopes we have. Astronomers believe quasars are produced by energy coming from over-fed, supermassive black holes, with most of them erupting 12 billion years ago.

The question is, why?  Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as we discuss these fascinating objects with the astronomers studying them using the Hubble Space Telescope. Learn about the latest research and explore the current thinking of what caused quasars and what was happening in the universe 12 billion years ago.
