Ken Kola Posted on December 13, 2012 - 04:54 Peering deep into
the past, astronomers using the Hubble Space Telescope have
identified seven primitive galaxies that formed more than 13
billion years ago, when the universe was less than three percent
of its present age. The newly-discovered galaxies are seen as
they looked 350 million to 600 million years after the big bang.
The discovery gives scientists the clearest picture yet of the
period when the very first galaxies were forming. It supports
the idea that they were created continuously over time, and
indicates that they may have provided enough radiation to
reheat, or reionize, the universe a few hundred million years
after the big bang.
