What is an irregular galaxy?

irregular galaxy usually refers to a galaxy that does not have a regular structure or shape, which means that it has small or no symmetry in rotation. Irregular galaxies can also be classified according to some unusual function that differs. This may include characteristics such as low surface brightness or strange gas streams that come from its core. Scientists estimate that irregular galaxies make up anywhere from 3% to 25% of space galaxies. The irregular galaxy has no of these rotations. In accordance with this, it is sometimes referred to as the fourth type of galaxy.

There are generally three classifications of irregular galaxies. The IRR-1 usually contains some type of standard structure, but it is not enough to be considered part of the Hubble sequence. The IRR-2 does not have a standard movement at all and often has a chaotic structure. The third type is known as the dwarf irregular galaxy. This galaxy has low levels of metallicity, which means it is largely composed of chemical elements of hydrogenAnd Helia. Since scientists believe that at the time of the Big Bang galaxies were made almost completely from hydrogen, it may indicate that the dwarf irregular galaxies are some of the oldest in the universe.

irregular galaxies tend to share some common features. In general, they have a weight that ranges from 108 to 1010 solar materials. Their diameters are between 1 to 10 kiloparsses. Its blue size -Mocking of apparent visual size -s can range from -13 to -20. Many irregular galaxies are also distinguished by large amounts of gas and dust.

There are many ways to create an irregular galaxy. For example, it is possible to result from Collisina galaxies. When this happens, the gravitational forces interact between separate galaxies, causing an irregular type of rotation. Young galaxy may also have an irregular form, suggesting that it has not yet reached symmetrical rotation.

some ungAvidal galaxies that have been identified include a large Magellan cloud (LMC). LMC is considered to be the third closest galaxy of the Milky Way. It is located between the constellations dorado and Mensa, at a distance of 163,000 light -years from Earth. Scientists speculate that its irregular shape is either the result of a collision between galaxies or that the gravitational forces of the Milky Way affect its rotation.

LMC also has a high amount of gas and dust, which is common to irregular galaxy. The LMC includes Tarantula Nebula, a very active area for stars. However, no scientific connection was made between irregular galaxies and potential to create stars.
