And some of these galaxy clusters are so massive they warp space-time around them. Hubble recently shared an image of one such galaxy cluster, a massive grouping known as Abell 1351.

Two galaxy clusters collided, creating a massive shock wave stretching out over 1.6 million light-years long. NASA’s Chandra X-ray Observatory spotted the shock wave earlier this month.
