El Gordo

This video shows a close-up of the galaxy cluster ACT-CL J0102−4915 nicknamed El Gordo—the “big” or “fat one” in Spanish. It consists of two separate galaxy sub clusters about 7 billion light-years from Earth that are colliding at several million kilometres per hour. The animation was put together using images taken by ESO’s Very Large Telescope and from the SOAR Telescope along with X-ray observations from NASA’s Chandra X-ray Observatory. The X-ray image shows the hot gas in the cluster and is shown in blue.
