The pair are located in the constellation of the Big Dipper: Ursa Major. The easiest way to find them is to first spot the bright star Dubhe, which forms the top point of the Big Dipper pan, then travel about 10 degrees northwest to spot the two galaxies. You also can photograph M81 and M82 without tracking the sky!
How far apart are M81 and M82?
12 million light-years
M81 (on the left), a “face-on” spiral galaxy, and M82 (on the right), seen “edge-on,” are a pair of galaxies in the constellation Ursa Major, near the “Big Dipper.” The apparent separation of the galaxies is 31 arc-minutes but at a distance of 12 million light-years, their actual distances from each other is 150,000 …
What is M81 and M82?
The M81 and M82 galaxies are a pair of galaxies located in the constellation, Ursa Major. 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.
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.
Can I see M81 with binoculars?
M81, also known as Bode’s galaxy, is a large bright spiral galaxy located 11.8 million light-years away in the constellation of Ursa Major. With an apparent magnitude of +6.9, it’s easily visible with binoculars and is a superb target for all sizes of telescopes.
What type 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.
Is the M82 a spiral?
Almost everything we know about M82, a spiral galaxy roughly 12 million light-years away, comes from studying the different forms of light—including infrared, visible, and X-ray light—that it gives off.
Is M82 in the Milky Way?
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?
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….
| Messier 82 | |
|---|---|
| Distance | 11.4–12.4 Mly (3.5–3.8 Mpc) |
| Apparent magnitude (V) | 8.41 |
| Characteristics | |
| Type | I0 |
Can you see M82 with binoculars?
M81 and M82 are bright enough to be observed with a pair of binoculars or a small telescope. In order to increase the detail and brightness of your image, however, a larger diameter telescope is required.
Who discovered M82?
Johann Elert Bode
M82 was discovered, along with its neighbor M81, by the German astronomer Johann Elert Bode in 1774. Located 12 million light-years from Earth in the constellation Ursa Major, M82 has an apparent magnitude of 8.4 and is best observed in April.
How far away is M82 from Earth?
11.42 million light years

What is the difference between the M81 and M82 galaxies?
M81 and M82. The M81 and M82 galaxies are a pair of galaxies located in the constellation, Ursa Major. M81 (Bode’s Galaxy) is a spiral galaxy that lies 11.8 million light years away, while M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth.
What happened to M81 and M82?
Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81’s spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays.
Where can I find the M81 / M82 pair?
First focus on Dubhe (α UMa – mag. +1.8), the northwest corner star of the bowl. The M81 / M82 pair is located 10 degrees to the northwest of this star with M82 positioned 38 arc minutes directly north of M81.

Which telescope used for my image of M81 and M82?
The telescope used for my image of M81 and M82 (Celestron RASA 8 F/2). Also cataloged as NGC 3031, Bode’s Galaxy is a spiral galaxy about 10 degrees northwest of the star, Dubhe. Using a telescope with a large aperture, it is possible to reveal the spiral structure of M81 under dark skies.
