Astronomers discovered that there is a missing link on their study with dark matter theories based on their new data from the Hubble telescope. Dark matter is the invisible glue that keeps stars bound together inside a galaxy and makes up the bulk of the matter in the Universe. Using Hubble imaging and VL T spectroscopy, the astronomers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.
