Astronomers shed light on the 'dark ages' of space following the Big Bang.
Cambridge University researchers have been able to look into the "Dark Ages" of space, a period between the Big Bang and the creation of the first stars. Light emitted from a massive black hole allowed the scientists to discover remnants of the first stars and the apparent explosion of a star 25 times larger than our sun.
Professor Max Pettini, of Cambridge's Institute of Astronomy, believes the find is a fossil record of the early universe. The researchers used the emitted light to measure gas clouds and the different elements within them, giving them a look into the elemental make up of early stars and their relative proportions, compared to current stars.
For years scientists have known 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.
