NGC 5457 (= M101 = PGC 50063 = Arp 26), The Pinwheel Galaxy
Discovered (Mar 27, 1781) by Pierre Méchain
Recorded (1781?) by Charles Messier as M101
An 8th-magnitude spiral galaxy (type SAB(rs)cd) in Ursa Major (RA 14 03 12.4, Dec +54 20 58)
Listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 26, an example of a spiral galaxy with one heavy arm. M101's recessional velocity of only 240 km/sec is too small in comparison to peculiar (non-Hubble-expansion) velocities to provide a reliable estimate of its distance. Redshift-independent distance estimates range from 18 to 29 million light years. Given that and its apparent size of 28 by 26 arcmin (nearly the same size as the full moon), M101 is nearly 200 thousand light years across. |
 Above, a "normal" size view of a huge (15000 pixel wide) mosaic of 51 HST images of the central portion of M101, superimposed on ground-based images to provide a view of the entire galaxy. The full-size mosaic is the most detailed image of a galaxy ever created with the HST.
