What are the names of some irregular galaxies?

The best known examples of irregular galaxies are the Small and Large Magellanic clouds. These are companion galaxies to our own Milky Way, and can be easily seen at dark sites in the Southern Hemisphere. The Large (left) and Small (right) Magellanic clouds are prime examples of irregular galaxies.

What is an example of a irregular galaxy?

The Large and Small Magellanic Clouds are examples of irregular galaxies. They are two small galaxies which orbit around our own Milky Way Galaxy. About 20% of all galaxies are irregulars.

How many types of irregular galaxy are there?

The shape of an irregular galaxy does not fall into any of the regular classes of the Hubble sequence. While not classified in the Hubble Classification System, irregular galaxies are classified into three categories: Irr-I (Irregular one), Irr-II (Irregular two) and dIrr (dwarf irregular).

Is the Andromeda an irregular galaxy?

A good example of this type is the Andromeda galaxy. ... They are very dim in comparison with the very bright spiral galaxies. Irregular galaxies are commonly small, and collectively they make up about a quarter of all the galaxies. They lack a distinct shape or form often having a chaotic appearance.

Is the Milky Way an irregular galaxy?

Our own Milky Way is a spiral galaxy, for example, and the largest galaxies in the Universe are elliptical galaxies. ... These are the irregular galaxies, and each one is unique in shape, age and structure. Irregular galaxies are often chaotic in shape, with no central bulge or spiral arms.

Where are irregular galaxies found?

Irregular galaxies are usually found in groups or clusters, where collisions and near-misses between galaxies are common. In a few irregular galaxies, astronomers can't figure out why they look so strange!

Do irregular galaxies have black holes?

The galaxy known as NGC 6240 is known as an irregular galaxy due to its particular shape. Until now, astronomers have assumed that it was formed by the collision of two smaller galaxies and therefore contains two black holes in its core.

What are the red clumps in irregular galaxies?

Likely stripped from the galaxy by gravitational tides, the tail contains mostly gas, dust, and newly formed stars. Two clusters of newly formed stars, warming their surrounding natal dust clouds, are seen in the tail as red spots.

Which type of irregular galaxy is made up of old stars?

Giant elliptical galaxies, on the other hand, can contain over a trillion stars. Elliptical galaxies are reddish to yellowish in color because they contain mostly old stars. Most elliptical galaxies contain very little gas and dust because they had already formed. However, some elliptical galaxies contain lots of dust.

What's a normal spiral galaxy?

type of galaxy

divided into two parallel classes: normal spirals and barred spirals. The normal spirals have arms that emanate from the nucleus, while barred spirals have a bright linear feature called a bar that straddles the nucleus, with the arms unwinding from the ends of the bar.

Do irregular galaxies have gravity?

Irregular galaxies have one-of-a-kind shapes and many look like blobs! ... When this happens, their gravity pulls stars out of place in both galaxies, messing up the neat structure they originally had as spiral or elliptical galaxies.

What are the 4 main galaxies?

Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.

What is M51 mean?

Messier 51 (M51), better known as the Whirlpool Galaxy, is a famous grand-design spiral galaxy located in the constellation Canes Venatici. The Whirlpool Galaxy has an apparent magnitude of 8.4 and lies at an approximate distance of 23 million light years from Earth.

What is the closest irregular galaxy?

The Canis Major Dwarf galaxy is an irregular galaxy, and, if it really exists, is probably the closest galaxy to our location in the Milky Way, though not the closest to the center of the Milky Way. It is about 25,000 light-years away from the Earth and 42,000 light-years from the center of the Galaxy.

What color is a irregular galaxy?

Most representatives of this class consist of grainy, highly irregular assemblages of luminous areas. They have neither noticeable symmetry nor an obvious central nucleus, and they are generally bluer in colour than are the arms and disks of spiral galaxies.

What is the 2nd closest galaxy?

Bottom line: The Triangulum galaxy, at 2.7 million light-years away, is the 2nd-closest large spiral galaxy. Because it is turned face-on to us, it appears faint in our sky.
