NASA: Hubble Telescope Finds Ring of Dark MatterUS Astronomers using NASA’s Hubble Space Telescope have been observing a star cluster CL0024+17 which is approximately 5 billion light years from Earth and running repeaded simulations to show that the observations yield the best proof to date of the existance of dark matter. Dark matter, a mysterious substance believed to make up more than a quarter of the universe and is suspected to be the glue that holds entire gallaxies together, is usually impossible to see directly. Light bending measurements from areas suspected of dark matter in the past have given indirect proof of dark matter. Now scientists believe they have lucked out with the perfect timing.
