As bright as a hundred million Suns: The clusters of monster stars that lit up the early universe

22 abril 2015

The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological ‘dark ages’ — when atoms of hydrogen and helium had formed, but nothing shone in visible light. Now researchers have calculated what these objects were like: they find that the first stars could have clustered together in phenomenally bright groups, with periods when they were as luminous as 100 million Suns.
