The Hubble Space Telescope took a picture of a huge cluster of galaxies that distorts the space-time around it. It is located in the constellation Draco at a distance of almost nine billion light years from Earth, according to NASA. Astronomers compare the cluster of galaxies to a submerged “sea monster stirring up waves on the surface of the water.” The massive mass of the cluster warps space-time, creating a gravitational lens that bends light from distant galaxies beyond the cluster.

Several other galaxies surrounding the cluster can also be seen in the photo. The stars that flash and are placed in the foreground are scattered throughout the image. This galaxy cluster is called eMACS J1823.1+7822 and is one of five massive galaxy clusters that Hubble studied to measure gravitational lensing forces. According to astronomers, this will make it possible to understand the distribution of dark matter in galaxy clusters. Powerful gravitational lensing, like that in eMACS J1823.1+7822, could help astronomers probe distant galaxies by acting like huge natural telescopes that magnify the most distant objects in space. It will be recalled that earlier the Hubble telescope recorded the last moments of the life of a star that was absorbed by a black hole.
