Arp 194 is one of 338 galactic curiosities grouped in a catalog called the Atlas of Peculiar Galaxies, which was organized in 1966 by astronomer Halton Arp. The Hubble Space Telescope recently imaged the galaxy group to reveal details on its dynamic interaction. The image celebrates Hubble’s 19th year of observing the cosmos. Hubble’s Wide Field Planetary Camera 2, which took this shot, was upgraded to a new, improved version on May 14.
