New research confirms that there are luminous red objects in the early cosmos – and that they cannot be explained by our understanding of how galaxies and black hole are born,
Researchers spotted three of the mysterious objects. Their light came to us from when the universe was only 600-800 million years old, about 5 per cent of its current age.
The objects appear to be filled with old stars and astonishingly massive black holes – neither of which were thought to have been able to form at such an early stage of the universe.
They made the discovery after looking for the intensity of different wavelengths of light. They look like very old stars, hundreds of millions of years old – but that would not be expected so early in the development of the universe.
They also spotted evidence of huge supermassive black holes in those same objects. They could be up to 1,000 times more massive than the supermassive black hole in our Milky Way, they suggest.
"It was totally unexpected to find old stars in a very young universe. The standard models of cosmology and galaxy formation have been incredibly successful, yet, these luminous objects do not quite fit comfortably into those theories."
