London: Astronomers
have uncovered the 'missing link' in the evolution of the universe
following the Big Bang.
For years the scientists knew nothing about the 'dark ages' of
space -- a period between the Big Bang, 13.7 billion years ago,
and the creation of the first stars.
But Cambridge University researchers have now captured light
emitted from a massive black hole to peer into this unknown
portion of the history of the universe.
They discovered remnants of the first stars and evidence of the
aftermath of an exploding star, which was a staggering 25 times
larger than the sun, the Daily Mail reported.
Max Pettini of Cambridge's Institute of Astronomy believes the
discovery of these gases could help reveal the origin of the
universe.
He said: "We have effectively been able to peer into the dark ages
using the light emitted from a quasar.
"The light provides a backdrop against which any gas cloud in its
path can be measured."
The Cambridge scientists teamed up with researchers at the
California Institute of Technology to carry out the
ground-breaking research.
