Visual Description: SDSS J1531

This is an image of a cluster of galaxies called SDSS J1531+3414 in X-ray, optical, and radio light. The overall scene resembles a colorful display of lights as if viewed through a wet, glass window. 

Blurry orange dots of different sizes are scattered across a black background. These orange dots are entire galaxies. Near the center of the image, two central galaxies appear as bright, white dots. Star clusters, resembling beads on a string in shades of electric blue, sweep over the galaxy on the left, through the space in between the galaxy pair, and then lightly coil beneath both galaxies. Clouds of blue, X-ray light, and dark pink, radio light, surround the two galaxies. 

The blue cloud spreads out for thousands of light-years toward the region above the central galaxies. The dark pink cloud, somewhat resembling the shape of an upside down spinning top toy, stretches far below the two galaxies and slightly toward our left. This dark pink cloud represents the remains of a powerful jet, produced by a supermassive black hole within one of the two central galaxies. In the upper right corner of the image, another dark pink cloud is present. This cloud may be the relic of a counter-jet from the same black hole outburst.
