The Whirlpool Galaxy (also known as M51 or NGC 5194) is a classic spiral galaxy located in the Canes Venatici constellation. It was discovered by Charles Messier on October 13, 1773.

The Whirlpool Galaxy is one of the brightest, most compelling galaxies in the sky, visible with binoculars. The spiral galactic structure was first observed in this galaxy, which is a dominant member of the M101 group of galaxies (M51 subgroup). NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light years in diameter and approximately 60 million light years distant. ... Binoculars Binocular telescopes, or binoculars, are two identical or mirror-symmetrical telescopes mounted side-by-side and aligned to point accurately in the same direction, one to be viewed through each of the users eyes. ... The M101 group of galaxies (or simply the M101 group) is a physical group and a galaxy cluster that comprises three of the most famous galaxies in the northern sky: M51, M101 and M63. ...


Its companion galaxy, NGC 5195, was discovered in 1781 by Pierre Méchain. Sometimes M51 is used to refer to the pair of galaxies, in which case the individual galaxies may be referred to as M51A (NGC 5194) and M51B (NGC 5195). The galaxy is less than 37 million light years away from Earth — some measurements put the distance at only 15 million. Irregular Galaxy NGC 5195 (also known as M51 B or NGC 5195) is an irregular galaxy in the Canes Venatici constellation. ... 1781 was a common year starting on Monday (see link for calendar). ...

Out of this whirl: The Whirlpool Galaxy (M51) and companion galaxy (459 words)
The galaxy is nicknamed the Whirlpool because of its swirling structure.
Some astronomers believe that the Whirlpool's arms are so prominent because of the effects of a close encounter with NGC 5195, the small, yellowish galaxy at the outermost tip of one of the Whirlpool's arms.
The Whirlpool is one of astronomy's galactic darlings.
