Irregular Galaxies: Oddly Shaped Mysteries of the Universe. When a very distant galaxy is examined with a very large telescope, we see its structure as it was when the light was emitted billions of years ago. So, how do irregulars form? Irr II are lacking any semblance of a shape. The majority of irregular galaxies are found in groups or large clusters. Whilst spiral and elliptical galaxies are named after their shape, the whole point of the irregular classification is that these types of galaxies generally do not have a shape, and therefore cannot fit into any other classification. A possible example of a S0 lenticular galaxy is Messier 86 . Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are . Irregular galaxies are known for the strange shape they take, as they have no central bulge or spiral. Irregular I Galaxies (Irr I): The first sub-type of irregular galaxies are known as Irr-I galaxies (Irr I for short) and are characterized by having some structure, but not enough to classify it as a spiral or elliptical galaxies (or any other type). This answer is: Study guides. Copy. However, they can also be very bright. Apparently, galaxies are much less well organized in their early years, and these very distant objects tend to be highly irregular and asymmetrical. Because of their small size, these types of galaxy are in danger of crashing into large galaxies. starburst irregular in M81 group), NGC 1313 (another starburst galaxy), NGC 6822 (irregular in Local Group). The most likely scenario is that two spirals either mingle together or simply pass very near each other, resulting in changes to both partners in the "galactic dance". Wiki User.

These do not have any previously discussed components, such as a bulge, disk, or arms, that other galaxies are known to have. Irregular galaxies contain both young and old stars, and substantial gas and dust. For one thing, many have sites of active star formation. The table below contains the names, selected cross identifications and positions for a number of these galaxies. Elliptical galaxies are the largest and most common galaxies observed. One of these is a dwarf irregular galaxy named IC 4710 , found in the constellation Pavo. In 4.5 billion years, scientists believe that the Andromeda Galaxy and Milky Way Galaxy will collide, crashing together to form a new, giant elliptical galaxy. Some may have been created simply by passing near another galaxy. Irr-II galaxies have an irregular shape that does not appear to feature any structure that can place it into the Hubble sequence. Or is there some other evolutionary path that they take? 10 Irregular Galaxy Facts You Should Know.
