Largest ever map of dark matter is created using light from 100 MILLION galaxies

The largest ever map showing where dark matter can be found throughout the universe has been created by astronomers using the light from 100 million galaxies. Using artificial intelligence to analyse images of the shape and light from galaxies, astronomers from University College London and the École Normale Supérieure in Paris created a map of the invisible matter throughout the universe. Dark matter makes up about 80 per cent of all matter in the universe, but isn't directly visible, spotted instead through its interaction with other objects. Working as part of the international Dark Energy Survey (DES), they looked for light travelling to Earth from distant galaxies being distorted by the dark matter. The team says an accurate map showing the spread of dark matter can one day help answer questions including what the universe is made of and how it has evolved. Co-lead author Dr Niall Jeffrey from École Normale Supérieure, Paris, and UCL told MailOnline that they've mapped about a quarter of the southern hemisphere sky so far, finding dark matter covering seven billion light years.
