Messier 82<\/strong> (also known as NGC 3034<\/strong>, Cigar Galaxy<\/strong> or M82<\/strong>) is a starburst galaxy<\/a> approximately 12 million light-years<\/a> away in the constellation<\/a> Ursa Major<\/a>. It is the second-largest member of the M81 Group<\/a>, with the D25<\/sub> isophotal diameter<\/a> of 12.52 kiloparsecs<\/a> (40,800 light-years<\/a>).[1]<\/a><\/sup>[5]<\/a><\/sup> It is about five times more luminous<\/a> than the Milky Way<\/a> and its central region is about one hundred times more luminous.[7]<\/a><\/sup> The starburst activity<\/a> is thought to have been triggered by interaction with neighboring galaxy M81<\/a>. As one of the closest starburst galaxies to Earth, M82 is the prototypical example of this galaxy type.[7]<\/a><\/sup>[a]<\/a><\/sup> SN 2014J<\/a>, a type Ia supernova<\/a>, was discovered in the galaxy on 21 January 2014.[8]<\/a><\/sup>[9]<\/a><\/sup>[10]<\/a><\/sup> In 2014, in studying M82, scientists discovered the brightest pulsar yet known, designated M82 X-2<\/a>.[11]<\/a><\/sup>[12]<\/a><\/sup>[13]<\/a><\/sup><\/p>\n\n\n\n

In November 2023, a gamma-ray burst<\/a> was observed in M82, which was determined to have come from a magnetar<\/a>, the first such event detected outside the Milky Way<\/a> (and only the fourth such event ever detected).[14]<\/a><\/sup>[15]<\/a><\/sup><\/p>\n\n\n\n

Discovery<\/h2>\n\n\n\n

M82, with M81<\/a>, was discovered by Johann Elert Bode<\/a> in 1774; he described it as a “nebulous patch”, this one about 3\u20444 degree away from the other, “very pale and of elongated shape”. In 1779, Pierre M\u00e9chain<\/a> independently rediscovered both objects and reported them to Charles Messier<\/a>, who added them to his catalog.[16]<\/a><\/sup><\/p>\n\n\n\n
