This Hubble image shows NGC 3156, a large lenticular galaxy some 73 million light-years away in the constellation of Sextans. The color image includes optical and near-infrared observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) instruments. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

SPT-CL J2215-3537 resembles a blue cloud with a hazy golden light at its core. The cluster is set against the blackness of space, which is dotted with white, orange and blue specks of light. A combination of X-ray, ultraviolet, optical, and infrared light, was used to create the image. The blue cloud represents X-ray gas observed by NASA’s Chandra X-ray Observatory. The cloud is soft, and uniform in texture. Over time, galaxy clusters often merge or collide. These collisions cause disturbances and sharp features in a cluster’s gas. When a cluster takes on a smooth, calm appearance, as found here in SPT-CL J2215-3537, it indicates that no such collisions have occurred for a very long time. Astronomers call these galaxy clusters ‘relaxed.’ The hazy golden light at the heart of the cloud represents a massive central galaxy with a large amount of star formation. This central galaxy is quite isolated within the blue gas cloud. There are relatively few nearby specks of light near the central galaxy, and none are as bright or as large. No other large galaxies have been found within 600,000 light-years of the central galaxy. This implies that SPT-CL J2215-3537 has not experienced a galaxy merger in the last billion years.
