Much of the mass in the El Gordo galaxy cluster is actually dark matter, shown here artificially colorized in blue. Scientists determined the location and concentration of the cluster’s dark matter by observing how its mass distorted the light from distant galaxies behind the cluster. Credit: NASA, ESA, and J. Jee (University of California, Davis).
