Abstract

NASA/JPL-CALTECH Quasar 40 million times the Sun's mass challenges theorists Astronomers have found by far the most distant and earliest quasar ever seen, a cosmic beacon shining so soon after the big bang that standard theory can't explain how it was built. To see whether any of those galaxy candidates harbored quasars, observers viewed the area with another NASA space observatory, Chandra, which can detect the x-rays that are the most reliable signature of quasars. Astronomers thought the black holes formed stepwise within early galaxies, as giant stars collapsed and merged, but quasars detected from when the universe was less than 1 billion years old have challenged the idea.
