| Description: | M 101 is an asymmetric spiral galaxy because its core is displaced from the center of its disk. Halton Arp called it a "Spiral with One Heavy Arm". The Chandra orbiting, X-Ray Observatory has recently found a possible new class of x-ray sources in M 101. These could be intermediate-sized black holes. There are two other members of the M 101 Group visible in this image. Click here to see them identified. |
