This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study .
Two very different galaxies feature in this image taken by the NASA/ESA Hubble Space Telescope, forming a peculiar galaxy pair called Arp Arp 116 is composed of a giant elliptical galaxy known as Messier and a much smaller spiral galaxy, NGC
This new image from the NASA/ESA Hubble Space Telescope captures an ongoing cosmic collision between two galaxies — a spiral galaxy is in the process of colliding with a lenticular galaxy. The collision looks almost as if it is popping .
