Our galaxy, the milky way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much dark matter as all the stars and gas put together and it's all held together by gravity like more than two-thirds of the known galaxies.
A galaxy is a huge collection of gas, dust, and stars held together by gravity most galaxies contain at least a trillion stars there are trillions of galaxies in the universe galaxies are grouped according to shape type the three galaxy types are elliptical, spiral and irregular. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy irregular galaxies do not fall into any of the regular classes of the hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of.

An irregular galaxy is a galaxy that does not have a spiral or elliptical structure, but is irregular in shape they are classified as type irr. Astronomers observe galaxies and categorize them according to four different kinds of shapes: elliptical, spiral, barred-spiral, and irregular.
Up to one quarter of all galaxies are irregular these do not fit into the classifications on the hubble tuning fork diagram because their shapes appear random and unordered. Irregular galaxy - free definition results from over 1700 online dictionaries. A slightly more extensive description of galaxy types based on their appearance is given by the hubble sequence since the hubble sequence is entirely based upon visual morphological type irregular galaxies often exhibit spaced knots of starburst activity active galaxy. Many irregular galaxies probably used to be spiral, or elliptical until they had some kind of accident which changed them such as crashing with another galaxy many other irregular galaxies probably were never spiral or elliptical they simply didn't evolve that way. Irregular galaxies hubble tuning fork galaxy clusters galaxy collisions other classifications conclusion your results: the hubble tuning fork in the early 1900s, edwin hubble looked at galaxies like the ones you saw in the last few pages hubble.
Irregular galaxies have no definite structure the stars are bunched up but the patches are randomly distributed throughout the galaxy finding the distances to the galaxies allows you to get a three-dimensional view of the galaxy positions. For descriptions that apply to both barred and non-barred spiral galaxies, choose spiral galaxies aspiral galaxies bbarred spiral galaxies celliptical galaxies dirregular galaxies 1)these galaxies are labelled as sba, sbb or sbc 2)it would be extremely. Introduction as the name suggests, irregular galaxies have no specific form, and so the group contains a very diverse selection of objects in fact, there are two types of irregular galaxy. Most galaxies fit one of the three previously described types, but about 3% of the galaxies we observe are very different these so-called irregular galaxies do not have a lot of common features. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy the shape of an irregular galaxy is uncommon they do not fall into any of the regular classes of the hubble sequence, and they are often chaotic in appearance, with neither a. The giant elliptical galaxy centaurus a shows a split personality because it hides a gaseous spiral at its core when centaurus a collided with a spiral galaxy 300 million years ago, it slurped up the spiral's gases, which formed a new spiral inside the larger galaxy.
Discovered by johann elert bode in 1774 messier 82 (m82, ngc 3034) is a remarkable galaxy of peculiar type in constellation ursa major it is usually classified as irregular, though probably a distorted disk galaxy, and famous for its heavy star-forming activity, thus a prototype member of the.
Irregular galaxy definition: nouna galaxy that does not have the clearly defined shape and structure of an elliptical, lenticular, or spiral galaxy irregular galaxies typically contain large amounts of gas and dust. Scientist believe the galaxies known as irregular galaxies are the result of several different outcomes, for instance the merger of a pair of galaxies, or a wondering galaxy t hat strays to close to a neighboring galaxy. Elliptical galaxies are dim collections of older stars, so they don't shine as brightly as spiral galaxies.
