Galactic Collision
Perks of not going out on weekdays.... Access and process images from hubble.
NGC 6621/NGC 6622 (Arp 81) - A beautiful peculiar pair of interacting galaxies. This image is a result of collision that occurred around 100 million years after their closest approach. It consists of NGC 6621 (to the left) and NGC 6622 (to the right).
NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped behind its body. The collision has also triggered extensive star formation between the two galaxies.
Scientists believe that Arp 81 has a richer collection of young massive star clusters than the notable Antennae galaxies (which are much closer than Arp 81). The pair is located in the constellation of Draco, approximately 300 million light-years away from Earth.
Arp 81 is the 81st galaxy in Arp's Atlas of Peculiar Galaxies. This image is part of a large collection of 59 images of merging galaxies taken by the Hubble Space Telescope and released on the occasion of its 18th anniversary on 24th April 2008. About the object Object name NGC 6621, NGC 6622, VV 247, Arp 81, VII Zw 778, KPG 534A Object description Interacting Galaxies Position (J2000) 18 12 54.70 +68 21 49.0 Constellation Draco Distance 300 million light-years (100 million parsecs)
