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 ).
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.
Note, however, that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 3049 could be approximately 19 .2 kpc (∼62,600 ly) if Hubble distance was used to calculate it.
NGC 4332 is a barred spiral galaxy [2] and a starburst galaxy [3] located 128 million light-years away [2] in the constellation Draco. The galaxy was discovered by astronomer William Herschel on March 20, 1790. [4] NGC 4332 is host to a supermassive black hole with an estimated mass of 9.5 × 10 7 solar masses. [5]
For example, the star formation rate of the Milky Way galaxy is approximately 3 M ☉ /yr, while starburst galaxies can experience star formation rates of 100 M ☉ /yr or more. [1] In a starburst galaxy, the rate of star formation is so large that the galaxy consumes all of its gas reservoir, from which the stars are forming, on a timescale ...
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 ...
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.
MS 1512-cB58 is a galaxy in the Boötes constellation. It is a starburst galaxy that is being strongly gravitationally lensed , magnifying its apparent size by 30−50 times. [ 4 ] [ 5 ]
