How are galaxies classified?
In 1926, Edwin Hubble proposed a classification system for galaxies, based on their shape as observed from Earth. The Hubble sequence divides regular galaxies into three broad classes: elliptical; lenticular and spiral. A fourth class is used for galaxies with irregular appearance.
What type of galaxy is galaxy NGC 4622?
spiral galaxy
NGC 4622 is a rare example of a spiral galaxy with arms pointing in opposite directions. What caused this galaxy to behave differently from most galaxies? Astronomers suspect that NGC 4622 interacted with another galaxy. Its two outer arms are lopsided, meaning that something disturbed it.
Which type of galaxy is lenticular?
A lenticular galaxy (denoted S0) is a type of galaxy intermediate between an elliptical (denoted E) and a spiral galaxy in galaxy morphological classification schemes. It contains a large-scale disc but does not have large-scale spiral arms.
What is M51 known as?
In M51, also known as the Whirlpool galaxy, these arms serve an important purpose: they are star-formation factories, compressing hydrogen gas and creating clusters of new stars.
What object is M51?
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 type of galaxy is M51?
The graceful, winding arms of the majestic spiral galaxy M51 appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust. Such striking arms are a hallmark of so-called grand-design spiral galaxies.
What is an Sc galaxy?
spiral galaxies In galaxy: Sc galaxies. These galaxies characteristically have a very small nucleus and multiple spiral arms that are open, with relatively large pitch angles.
