UGC 1840, also known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the Solar System in the Andromeda constellation. [2] The earliest known reference to the pair of galaxies is in part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +07-06-002. [3]

2021年4月22日 · Arp 145 (UGC 1840, PGC 9062 and others) is the result of a head on collision of elliptical and spiral galaxies. This one is in Arp’s “E and E-like galaxies – Material emanating from E galaxies” class. It is located about a degree from NGC 891 and approximately 258 million light-years away in Andromeda.

Arp 145 falls into the Arp category material emanating from elliptical or elliptical-like galaxies. In this case what is going on is more obvious. This is a case of a direct hit by an elliptical galaxy (lower left) on a near face on spiral galaxy (upper right).

Arp 145, aka UGC 1840, MCG+07-06-002 or LEDA/PGC 9062 (pick your galaxy catalog!) is a distant disrupted spiral galaxy in Andromeda. It looks me to actually be a pair of galaxies mid-interaction, at least one of which is a spiral.

Three bright stars (2 lower left and 1 upper right) seem to be superimposed over the galaxies, so just ignore them. It looks like the elliptical galaxy passed right through the spiral galaxy and left a "black hole" in its wake. The core of the spiral is seen displaced to the left.
