Image of Arp 1, also known as NGC 2857, from the Atlas of Peculiar Galaxies by Halton Arp (1966).In the original catalog, it was in the category: Spiral galaxies - Low surface brightness. It is a spiral galaxy in the constellation Ursa Major.Source: https://ned.ipac.caltech.edu/level5/Arp/Arp1.html#ArpGalaxy #Galaxy #Space #Astronomy

MegaCam Canada-France-Hawaii Telescope image of Arp 227, also known as NGC 470 and NGC 474.The large lenticular galaxy (NGC 474, left) is interacting with a smaller companion spiral galaxy (NGC 470, right). NGC 474's spectacular shells and tidal tails may be the result of a past merger with a smaller galaxy.Credit: Canada-France-Hawaii Telescope, CoelumSource: https://www.cfht.hawaii.edu/hawaiianstarlight/AIOM/English/CFHT-Coelum-AIOM-Jul2013.html#ArpGalaxy #Galaxy #Space #Astronomy #CFHT

Hubble image of Arp 107, also known as UGC 5984.The one-armed spiral and its smaller elliptical companion galaxy are gravitationally interacting with one another, which is likely responsible for the spiral galaxy's unusual shape, as well as the bridge of gas and stars that connects the two galaxies.Credit: ESA, NASA, J.

Hubble and Dark Energy Camera image of Arp 122, also known as NGC 6040 and LEDA 59642.This pair of galaxies NGC 6040, the tilted, warped spiral galaxy and LEDA 59642, the round, face-on spiral are in the midst of a collision.Credit: ESA, NASA, J.

Image of Arp 284, also known as NGC 7714 and NGC 7715, from the Atlas of Peculiar Galaxies by Halton Arp (1966).In the original catalog, it was in the category: Double and multiple galaxies - Infall and attraction. NGC 7714 (bottom) and NGC 7715 (top) had a close encounter about 100 million to 200 million years ago. This created a bridge between the galaxies and a loop of stars extending from NGC 7714.Source: https://ned.ipac.caltech.edu/level5/Arp/Arp71.html#ArpGalaxy #Galaxy #Space #Astronomy

Sloan Digital Sky Survey image of Arp 13, also known as NGC 7448.NGC 7448 has a disk of tightly wound, clumpy, and particularly bright spiral arms.Credit: SDSSSource: https://commons.wikimedia.org/wiki/File:NGC7448_-_SDSS_DR14.jpg#ArpGalaxy #Galaxy #Space #Astronomy

Ground-based image of Arp 16, also known as M66.M66 is a member of the Leo Triplet. NGC 3628, the galaxy in the upper left, likely had an encounter with M66 a few hundred million years ago, creating a dramatic tail-like plume.Gravitational interactions between the three galaxies may also be responsible for M66’s distorted shape and prominent spiral arms.Credit: Fig 1, G.
