<\/div>Fossil Clouds<\/h2>
Astronomers at the M. Keck Observatory on Maunakea, Hawaii made an incredible discovery earlier this month. It was a rare relic of the ancient universe: a “fossil cloud” of gas created around the time of the Big Bang.<\/p>
The extraordinary discovery could provide new information about the origins of the universe and its early composition — including why certain stars and galaxies formed from gases and others didn’t.<\/p>

The group was led by Fred Robert and Michael Murphy, both at Swinburne University of Technology in Melbourne. Their results are about to be published in an astronomical journal called Monthly Notices of the Royal Astronomical Society, but they’ve also made them available on the preprint server arXiv<\/a>.<\/p> “Everywhere we look, the gas in the universe is polluted by waste heavy elements from exploding stars,” said Robert in a statement<\/a> on the Keck Observatory’s website. “But this particular cloud seems pristine, unpolluted by stars even 1.5 billion years after the Big Bang.”<\/p> The team used two M. Keck Observatory spectrometers — think of them as extremely sensitive and complex cameras — that have been used to discover exoplanets<\/a> in the past.<\/p> The astronomers spotted the fossil cloud because of an extremely bright quasar — a celestial object that emits large amounts of energy — behind it. The spectrometer readings found the cloud to be extremely low in density, leading them to believe it was a “true relic of the Big Bang,” according to Robert, since they remained almost entirely unaffected by exploding star particles that fill the rest of the galaxy.<\/p> And many more such fossil clouds could be discovered in the future thanks to this particular discovery — the first two fossil clouds were actually found by accident in 2011 — Robert and his team knew to look for this third one.<\/p> “It’s now possible to survey for these fossil relics of the Big Bang,” said Murphy. “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.”<\/p> READ MORE: <\/strong>Astronomers find a ‘fossil cloud’ uncontaminated since the Big Bang<\/a> [Astronomy]<\/p> More on the Big Bang: An Ancient Star Reveals Our Galaxy Is Older Than We Thought<\/a><\/strong><\/em><\/p> The post Astronomers Found Ancient Remains of a Big Bang “Fossil Cloud”<\/a> appeared first on Futurism<\/a>.<\/p> Read the rest here: Fossil Clouds Astronomers at the M.
