Latest Pinwheel Galaxy Stories
The Hubble Space Telescope has revealed a new image of the galaxy Messier 83, which has hosted a large number of supernova explosions and is believed to have a double nucleus at its core.
known as M101, the galaxy lies 21 million light-years away in the constellation Ursa Major. It measures 170 000 light-years across – nearly twice the diameter of our own Milky Way Galaxy – and contains at least a trillion stars. About a billion of these stars could be similar to our own Sun.
Astronomers will be losing sleep as they wait on a newly discovered supernova to reach its peak in brightness on Thursday and Friday.
ESO's Wide Field Imager has captured the intricate swirls of the spiral galaxy Messier 83, a smaller look-alike of our own Milky Way.
Giant galaxies weren't assembled in a day. Neither was this Hubble Space Telescope image of the face-on spiral galaxy Messier 101 (M101). It is the largest and most detailed photo of a spiral galaxy that has ever been released from Hubble.
The Swift satellite's Ultraviolet/Optical Telescope (UVOT) has seen first light, capturing an image of the Pinwheel Galaxy, long loved by amateur astronomers as the "perfect" face-on spiral galaxy. The UVOT now remains poised to observe its first gamma-ray burst.
The M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...
Pinwheel Galaxy -- Discovered by Pierre Mchain in 1781. M101 was discovered by Pierre Mchain on March 27, 1781, and added as one of the last entries in Charles Messier's catalog. It was the first "spiral nebula" identified as such by William Parsons, the third Earl of Rosse. Although extended 22 arc minutes on photos and quite bright, only the central region of this galaxy is visible in smaller telescopes, best at low powers. Suggestions of the spiral arms can be glimpsed in...
