This image of the galaxy cluster MACSJ1423 is a 3-color optical image from the Subaru prime focus camera. It shows white and blue galaxies centered around a large elliptical galaxy. The mass of the hot gas is about 6 times greater than the mass of all the billions of stars in all of the galaxies in the cluster. This galaxy cluster has a redshift of 0.54, at a distance corresponding to a light travel time of 5.4 billion years. Scale: Image is 2.56 x 1.6 arcmin
