This image, taken by the NASA Hubble Space Telescope, demonstrates the magnificent galaxy UGC 12591. Classified as S0 / Sa, it lies between the lens-shaped and spiral-like types. Located 400 million light-years from us in the western supercluster area of the Fishes-Perseus. It is a long chain of galactic clusters stretching for hundreds of light years (one of the largest known cosmic structures).
The object itself is also uncommon and incredibly massive. The galaxy and its halo contain hundreds of billions of stars, whose size several times exaggerate the sun, and the total mass is four times the Milky Way. Its rotation is also much faster, at 1.8 million km per hour. Hubble's observations help astronomers understand the mass of UGC 12591. This will also explain whether it is just an educated galaxy that has been growing over time, or has become so massive due to the collision and merger with another large galaxy in the distant past.
