Is Messier 82 a spiral galaxy?
Is Messier 82 a spiral galaxy?
Messier 82 (also known as the Cigar Galaxy, NGC 3034 or Arp 337) is an edge-on spiral galaxy that lies approximately 11.5 million light-years away from Earth in the constellation of Ursa Major (the Great Bear), while it is receding from us at about 203 kilometers per second.
What shape is messier82?
Messier 82 is located about 12 million light-years away in the Ursa Major constellation. It is viewed from its side, or edge on, so it appears as a thin cigar-shaped bar. The galaxy is termed a starburst because its core is a fiery hotbed of stellar birth….

Is Messier 82 irregular?
Messier 82 (M82, NGC 3034) is a remarkable galaxy of peculiar type in constellation Ursa Major. It is usually classified as irregular, though probably a distorted disk galaxy, and famous for its heavy star-forming activity, thus a prototype member of the class of starbursting galaxies.
What is the diameter of the Cigar Galaxy?
37,000 light yearsMessier 82 / Diameter
The Cigar Galaxy occupies an area of 11.2 by 4.3 arc minutes of apparent sky, which corresponds to a linear diameter of about 37,000 light years.
Why is Messier 82 called Messier 82?
Messier 82 was discovered by Charles Messier, who subsequently included the galaxy in his catalogue in the late 18th century. Messier 82 and Messier 81 make a striking pair when observed in small telescopes.
Why is Messier 82 called the 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 elliptical shape produced by the oblique tilt of its starry disk relative to our line of sight.

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.
How far away is Andromeda?
2.537 million light yearsAndromeda Galaxy / Distance to Earth
At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way’s largest galactic neighbor. The entire galaxy spans 260,000 light-years across – a distance so large, it took 11 different image segments stitched together to produce this view of the galaxy next door.
How far apart are M81 and M82?
150,000 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 …
How far away is Bode’s galaxy?
11.74 million light yearsMessier 81 / Distance to Earth
Bode’s Galaxy is one of the brightest galaxies in the night sky and is located about 11.5 million lightyears from Earth. It can even be seen through a pair of binoculars, appearing as a fuzzy patch along side its companion, the Cigar Galaxy.
How big are dwarf galaxies?
200 light years across
Ultra-compact dwarf galaxies (UCD) are a class of very compact galaxies with very high stellar densities, discovered in the 2000s. They are thought to be on the order of 200 light years across, containing about 100 million stars.
