Arp 148


arp 148Mayall’s Object is classified in the Atlas of Peculiar Galaxies as Arp 148. It is believed to be the result of two colliding galaxies located 500 million light years away within the constellation of Ursa Major. Astronomers believe that a pair of galaxies collided, resulting in a new object consisting of a ring-shaped galaxy with a tail emerging from it. It is thought that the original collision created a shockwave that initially drew matter into the center which then formed the ring.

M106


Messier_106_visible_and_infrared_compositeMessier 106 is a spiral galaxy in the constellation Canes Venatici. It’s about 22 to 25 million light-years away from Earth. Because of x-rays and unusual emission lines detected, astronomers believe that matter in the galaxy is falling into a supermassive black hole in the center. This image is a composite of x-ray (blue), visible light, infrared (red), and radio (purple) data.

Arp 188


Tadpole Arp 188The Tadpole Galaxy is a disrupted barred spiral galaxy 420 million light-years from Earth in the constellation Draco. Its most dramatic features is a trail of stars about 280,000 light-years long and massive, bright blue star clusters. Like a tadpole here on Earth, the galaxy will likely lose its tail as it grows older—the tail’s stars will probably form smaller satellite galaxies of the larger spiral.
