Messier 82 : is an irregular galaxy located at about 4.5 Mcf (~ 14.7 million a.l) from the Earth in the constellation Ursa Major1. Also called Cigar galaxy. Was first discovered by Johann Elert Bode on December 31, 1774 together with M81; he described it as a "nebulous patch", about 0.75 deg away from M81, "very pale and of elongated shape". In 1779, Pierre Méchain independently rediscovered both galaxies and reported them to Charles Messier, who added them to his catalog.
