A GALEX ultraviolet image of the interacting galaxies M81 and M82, which lie 12 million light-years away in the constellation Ursa Major. The gravity from each galaxy dramatically affected the other during their last close encounter, 200 million years ago. Gas density waves rippling around M81 make it a grand design spiral. M82 is undergoing a starburst at its core, creating glowing fingers of hydrogen.
The Seyfert galaxy NGC 1097, in the constellation of Fornax (The Furnace), is seen in this image taken by ESO’s Very Large Telescope (VLT). A tiny elliptical companion galaxy, NGC 1097A, is also visible at the top left. NGC 1097, the larger galaxy, also has four faint jets — too faint to be seen in this image — that emerge from its center, forming an X-shaped pattern, and are the longest visible-wavelength jets of any known galaxy.
