The Hubble Space Telescope has a new image release. The two galaxies are located far away from Earth. The odd-shaped galaxy on the bottom right is called IC 563, while the spiral on the top left is called IC 564.
The Atlas of Peculiar Galaxies is a catalog of unusual galaxies produced by astronomer Halton Arp in 1966. The California Institute of Technology published an original version of his atlas in 1966.
The examples of the different kinds of peculiar structures found in the universe were what Arp wanted to show in his catalog. Some of the objects in the catalog were entered as groups of galaxies, while others were entered as interacting galaxies.
A distorted shape is what interacting galaxies usually have, while galaxy groups are simply bound to each other but not necessarily close enough to cause major structural changes.
The two galaxies are not very close to each other, but they look distorted. The objects in his atlas are mostly interacting galaxy pairs.
The Hubble Space Telescope can zoom in on individual galaxies with multiple instruments, so this image was created from two separate Hubble observations. The first used Hubble's Wide Field Camera 3 to study the pair's clumpy star-forming regions. According to the Hubble team, IC and IC are both very bright and host many bright star-forming regions.
The second observation was taken with Hubble's Advanced Camera for Surveys to take quick looks at bright, interesting galaxies across the sky. The observations filled gaps in Hubble's archive and looked for promising candidates that could be studied further.
