Image of the central region of SpARCS1049
This image, using data from Spitzer and the Hubble Space Telescope, shows the central region of the galaxy cluster SpARCS1049. The brightest cluster galaxy in the center of the cluster is currently undergoing a wet merger which produces enormous amounts of new stars. The tidal tail — an indicator of the merger — as well as the brightest cluster galaxy itself are shown.
