What is the name of an elliptical galaxy?

What is the name of an elliptical galaxy?

One of the most famous elliptical galaxies is Cygnus A, which is located roughly 600 million light-years from Earth and is an extremely bright radio source.

What kind of galaxy is E0?

E0 are considered ‘early-type’ ellipticals and E7 are ‘late-type’ ellipticals. Located in the fork of the Hubble classification diagram and intermediate between the elliptical and spiral galaxies are the S0/SB0 galaxies. These galaxies show prominent bulges, but no spiral arms.

What is the difference between an E0 and an E9 galaxy?

For ellipticals, a number from 0 to 9 indicates the eccentricity of the elliptical. For example, an E0 is more spherical than an E1. An E9 elliptical has a high eccentricity, so it is very oval in appearance. Elliptical galaxies generally have older star populations, so they are redder in appearance.

How many elliptical galaxies are there in the universe?

100,000,000,000 galaxies
Explanation: There are 100,000,000,000 galaxies in the universe (best guess). 20 percent of known galaxies are elliptical.

What are some examples of elliptical galaxies?

Examples of elliptical galaxies are M32 (an E2 dwarf elliptical next to the Andromeda Galaxy) and M87 (a huge elliptical in the center of the Virgo cluster ).

What are the types of elliptical galaxies?

Elliptical galaxies are divided into three ‘stages’: compact ellipticals (cE), normal ellipticals (E) and late types (E +). Lenticulars are similarly subdivided into early (S −), intermediate (S 0) and late (S +) types. Irregular galaxies can be of type magellanic irregulars (T = 10) or ‘compact’ (T = 11).

How do you describe elliptical galaxies?

Elliptical galaxies are shaped like a spheriod, or elongated sphere. In the sky, where we can only see two of their three dimensions, these galaxies look like elliptical, or oval, shaped disks. The light is smooth, with the surface brightness decreasing as you go farther out from the center.

What are facts about elliptical galaxies?

Elliptical galaxies are made up of mostly old stars, and do not have much gas and dust. There is very little new star formation in these galaxies. Elliptical galaxies also come in many sizes. The largest galaxies we see are ellipticals, but, elliptical galaxies can also be small. About 60% of all galaxies are ellipticals.
