What happened to M81 and M82?
M81 (Bode’s Galaxy) is a spiral galaxy that lies approximately 11.8 million light-years away, while M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth. These galaxies have a gravitational lock on each other and have affected the shape and composition of one another.
Is M82 in our galaxy?
M82 or the Cigar galaxy, shines brightly at infrared wavelengths and is remarkable for its star formation activity. Around the galaxy’s center, young stars are being born 10 times faster than they are inside our entire Milky Way galaxy.
What kind of galaxy is M82?
Cigar Galaxy
Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major….

| Type | I0 |
Where is M82 in the night sky?
constellation Ursa Major
Located 12 million light-years away, M82 appears high in the northern spring sky in the direction of the constellation Ursa Major, the Great Bear. It is also called the “Cigar Galaxy” because of the elliptical shape produced by the oblique tilt of its starry disk relative to our line of sight.
How far is M82 galaxy from Earth?
11.42 million light yearsMessier 82 / Distance to Earth
Why is it called Cigar Galaxy?
Located 12 million light-years away, M82 appears high in the northern spring sky in the direction of the constellation Ursa Major, the Great Bear. It is also called the ‘Cigar Galaxy’ because of the elongated elliptical shape produced by the tilt of its starry disk relative to our line of sight.

Did an object in M82 send out radio waves?
In April 2010, radio astronomers working at the Jodrell Bank Observatory of the University of Manchester in the UK reported an object in M82 that had started sending out radio waves, and whose emission did not look like anything seen anywhere in the universe before.
What is the origin of the galaxy M82?
M82 was first discovered by Johann Elert Bode on 31 December 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.
What is happening to the spiral M82?
M82 is being physically affected by its larger neighbor, the spiral M81. Tidal forces caused by gravity have deformed M82, a process that started about 100 million years ago. This interaction has caused star formation to increase tenfold compared to “normal” galaxies.
What is M82’s unique bipolar outflow?
M82’s unique bipolar outflow (or ‘ superwind ‘) appears to be concentrated on clumps A and C and is fueled by energy released by supernovae within the clumps which occur at a rate of about one every ten years. The Chandra X-ray Observatory detected fluctuating X-ray emissions about 600 light-years from the center of M82.
