Researchers have used a giant telescope to uncover a fossil from the Big Bang — a gas cloud 1.5 billion years old.
The discovery of such a rare fossil offers new insights on how the universe’s first galaxies formed.
The pristine gas cloud was spotted by Swinburne University of Technology PhD student Fred Robert and Professor Michael Murphey.
It’s lack of pollution is what makes it so important.
“Everywhere we look, the gas in the universe is polluted by waste heavy elements from exploding stars,” says Mr Robert.
“But this particular cloud seems pristine, unpolluted by stars even 1.5 billion years after the Big Bang.”
Professor Murphy says that it is now possible to survey for these fossil relics of the Big Bang.
“That will tell us exactly how rare they are and help us understand how some gas formed stars and galaxies in the early universe, and why some didn’t.”
Research to unlock the secrets of the universe is only possible if we support our universities. To keep Australia clever, please sign the petition below.
