| Notes | M51 is located about 31 million lights years from earth. This beautiful face-on spiral and its companion, NGC 4199 are gravitationally bound and locked in a deep space dance. Lord Rosse observed this object with his 72 inch speculum reflector from Birr Castle, Ireland in 1845 and reported it to have a spiral structure. This image was featured in the Gallery section of the May 2005 issue of Sky & Telescope Magazine. |
