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. It is the second-largest member of the M81 Group , with the D 25 isophotal diameter of 12.52 kiloparsecs (40,800 light-years ).
The Antennae Galaxies are an example of a starburst galaxy occurring from the collision of NGC 4038/NGC 4039. Credit: NASA/ESA. A starburst galaxy is one undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy, or the star formation rate observed in most other galaxies.
It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs). [ 1 ] This is a list of largest galaxies known, sorted by order of increasing major axis diameters.
NGC 3125 is a large starburst galaxy in the constellation Antlia.It is located approximately 50 million light-years away from Earth.Starburst galaxies are galaxies in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.
For comparison, the Milky Way has a diameter of at least 26,800 parsecs ... M82, a starburst galaxy that has ten times the star formation of a "normal" galaxy [111]
Starburst regions can occur in different shapes, for example in Messier 94 the inner ring is a starburst region. [5] Messier 82 has a starburst core of about 600 parsec in diameter. [3] Starbursts are common during galaxy mergers such as the Antennae Galaxies. In the case of mergers, the starburst can either be local or galaxy-wide depending on ...
UGC 6697 is a large irregular [1] spiral galaxy with a bar [2] located in the Leo constellation. [3] It is located 378 million light-years from the Solar System and has an estimated diameter of 205,000 light-years. [4] UGC 6697 is considered a starburst galaxy which produces high rates of star formation.
The galaxy was discovered in 1876 by Friedrich August Theodor Winnecke. [ 3 ] It has a diameter of 80,000 lyr. [ 3 ] The galaxy's most conspicuous feature is the dusty lanes of a spiral arm lying across the core of the galaxy as seen from Earth, the arm having been bent 45 degrees by a close encounter with a smaller galaxy possibly NGC 2146a ...
