a galaxy with no definite structure. Stars are distributed in bunches placed randomly throughout the galaxy. Many irregular galaxies have a lot of gas and dust still left in them from which stars are now forming.
() type of galaxy that does not fit the form of a spiral galaxy or elliptical galaxy.
a cluster of stars and other celestial matter
A galaxy without spiral arms that has a chaotic appearance.
A galaxy lacking visible organized structure. Irregular galaxies often show evidence of rapid star formation. M82 in Ursa Major is a classic example of an irregular galaxy.
galaxy with a very irregular shape and no obvious elliptical or spiral structure. They are classified as type Irr. Irregular galaxies with a crude spiral-like structure are often classified as type Sm (or type SBm if they also have a central bar).
A strangely shaped galaxy, often rich in interstellar matter, but apparently not a member of any of the major classes of spiral or elliptical galaxies.
A galaxy with no spiral structure and no symmetric shape. Irregular galaxies are usually filamentary or very clumpy in shape.
A galaxy without rotational symmetry; neither a spiral nor an elliptical galaxy.
An irregular galaxy is a galaxy with no rotational symmetry (it is neither spital, elliptical nor lenticular). Irregular galaxies usually contain only 100 million to 10 billion stars. Some are cloud-lie (with no apparent structure) and others are more standard shapes that have been distturbed. For example, the Magellanic Cloud is an irregular galaxy.
A galaxy that does not fit into the shape categories of elliptical and spiral galaxies.
A galaxy with a chaotic appearance, large clouds of gas and dust, and both population I and population II stars, but without spiral arms.
galaxy without symmetrical form.
An irregular galaxy is a galaxy that does not fall into the Hubble classification for galaxies. These are galaxies that feature neither spiral nor elliptical morphology. They are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
