This composite image shows Abell 1758, a quadruple galaxy cluster system about 3 billion light-years away from Earth. In the northern (top) pair seen in the image, the centers of each cluster have already passed by each other once, about 300 to 400 million years ago, and will eventually swing back around. The southern pair at the bottom of the image has two clusters that are close to approaching each other for the first time. X-rays from Chandra are shown as blue and white, depicting fainter and brighter diffuse emission, respectively. This image also includes an optical image from the Sloan Digital Sky Survey (SDSS).

Using data from NASA’s Chandra X-ray Observatory, astronomers have created detailed maps of Abell 1758, a collision between two pairs of galaxy clusters,...

This Hubble image shows A1758N, the northern part of the galaxy cluster Abell 1758. The cluster is approximately 3.2 billion light-years from Earth and is part of a larger structure containing two clusters sitting some 2.4 million light-years apart. But A1758N itself is further split into two sub-sections, known as East (A1758NE) and West (A1758NW). Image credit: NASA / ESA / Hubble.
