A fraction of this mass is locked up in several hundred galaxies that inhabit the cluster and a larger fraction is in hot gas that fills the entire volume of the cluster. It's like looking at a giant's head and shoulders from the side, say researchers. Have any problems using the site? "It's given us an even stronger probability that this is really an amazing system very early in the universe.". This picture of the galaxy cluster ACT-CL J0102-4915 combines images taken with ESO's Very Large Telescope with images from the SOAR Telescope and X-ray observations from NASA's Chandra X-ray Observatory. Humans are 8% virus. We were in dire need for an independent and more robust mass estimate given how extreme this cluster is and how rare its existence is in the current cosmological model. There was all this kinematic energy that was unaccounted for and could potentially suggest that we were actually underestimating the mass, Felipe Menanteau of the University of Illinois at Urbana-Champaign said. They were able to put together estimates of the cluster's mass based on the motions of the galaxies moving inside the .
