Grand Spiral Galaxy M81 and Arp's Loop
M81 is one of the brightest galaxies in the sky. It is 11.8 million light-years away near Ursa Major. This photo shows the bright core and the spiral arms of the galaxy. Arp's loop is the grand arc at the upper right of the galaxy. It has been found that some of this loop reaches our own galaxy. The image shows bright stars and dust clouds, along with Holmberg IX, the companion galaxy.
