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.
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.
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.
Kiso 5639 (also known as LEDA 36252, KUG 1138+327 or the Skyrocket Galaxy) is an irregular dwarf galaxy in the constellation Ursa Major, approximately 85 million light-years from Earth. [1] It has an elongated and flattened shape, with a maximum diameter that extends for approximately 2,700 light years. [ 2 ]
It is a starburst galaxy and it is likely that NGC 3310 collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. It is thought to be located approximately 46 million light-years away from the Earth , and is thought to be about 22,000 light-years wide.
The NGC 1569 starburst is believed to have been triggered by interactions with other galaxies of the IC 342 group, in particular a nearby cloud of neutral hydrogen. [ 5 ] [ 10 ] A 2013 study suggested the presence of tidal tails linking this galaxy with IC 342 and the dwarf galaxy UGCA 92 (see below) whose nature, however, is unclear and may ...
The galaxy lies at a distance of 25 million light years from Earth making it located in the local universe. It interacts with its smaller companion NGC 4485 and as a result is a starburst galaxy . NGC 4490 and NGC 4485 are collectively known in the Atlas of Peculiar Galaxies as Arp 269.
