Early universe 'warmed up' later than previously believed: Research suggests a way to detect the earliest black holes Posted: 05 Feb 2014 11:38 AM PST A new study reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature in radio waves which astronomers can now search for. The study is a major new finding about the origins of the universe.

Heavy metal in the early cosmos: Simulations shed light on formation and explosion of stars in earliest galaxies Posted: 05 Feb 2014 11:38 AM PST Researchers have simulated the formation of the Universe from the Big Bang through the first few hundred million years of its existence. The researchers found that more realistic models of supernova blasts help explain the range of metalicity found in different galaxies. The results of the simulations will assist in guiding the James Webb Space Telescope, set to launch in 2018.
