The universe’s first known stars have been identified by astronomers. They date almost <\/a>to the dawn of time – around 13.7 billion years ago. Studying their remains will shed fresh light on the early cosmos.<\/p>\n\n\n\n

An Italian team identified the ashes using the Very Large Telescope in Chile.<\/p>\n\n\n\n

They used light from quasars – incredibly bright objects at the centers of distant galaxies \u2013 to detect their existence.<\/p>\n\n\n\n

Lead author Professor Stefania Salvadori, of Florence University in Italy, said:<\/p>\n\n\n\n

\n

“Our discovery opens new avenues to indirectly study the nature of the first stars.”<\/p>\n<\/blockquote>\n\n\n\n

Quasars are black holes with energetic jets beaming out from two sides.<\/p>\n\n\n\n

As the light propagates it passes through clouds of gas that absorb certain wavelengths depending on what elements they contain.<\/p>\n\n\n\n

The researchers used this absorption to pick out three distant gas clouds nearly 25 billion light years away with strange chemical signatures.<\/p>\n\n\n\n

They observed them as they appeared over 11 billion years ago – around two billion years after their birth, reports New Scientist.<\/p>\n\n\n\n

Gas clouds are often left behind after a star explodes in a supernova – blasting away its contents.<\/p>\n\n\n\n

But astronomers expect some of the first stars wouldn’t have exploded completely – leaving their cores and the heavier elements inside intact.<\/p>\n","protected":false},"excerpt":{"rendered":"
