How do you identify elliptical galaxies?

Elliptical galaxies are defined by their relative lack of a sharply defined pattern or disk. They have no spiral arms, and are instead a ellipsoid bulge of stars orbiting with random inclinations (tilts) and directions around the center of mass.

Why is it called elliptical galaxy?

One of the most common types are elliptical galaxies, named because they have an ellipsoidal (or egg) shape, and a smooth, almost featureless appearance. They’re the result of many collisions between smaller galaxies, and all these collisions have destroyed the delicate spiral structure that we see in our own galaxy.

Which phrase describe an irregular galaxy?

The answer is D. “An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.

Which characteristics best describe an elliptical galaxy?

Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies. Instead, they bear the rounded shape of an ellipse, a stretched-out circle.

What are the characteristics of galaxies?

Galaxies are sprawling systems of dust, gas, dark matter, and anywhere from a million to a trillion stars that are held together by gravity. Nearly all large galaxies are thought to also contain supermassive black holes at their centers.

What defines a galaxy?

What are the characteristics of a irregular galaxy?

Irregular galaxies have no particular shape. They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright.

What kind of galaxy is an elliptical galaxy?

Elliptical galaxies are shaped like ellipses (stretched circles). They are divided into eight types: E0-E7 depending on how elliptical they are. E0 ellipticals are nearly circular, while E7s are very stretched out. Elliptical galaxies are made up of mostly old stars, and do not have much gas and dust.

What are some adjectives used to describe a galaxy?

Each word below can often be found in front of the noun galaxy in the same sentence. This reference page can help answer the question what are some adjectives commonly used for describing GALAXY. andromeda, bright, brilliant. distant, elliptical, entire. glorious, great, new. other, own, same. spiral, splendid, whole.

Why are elliptical galaxies more violent than other galaxies?

Because elliptical galaxies contain older stars and less gas, scientists think that they are nearing the end of the evolutionary line for galaxies. The universe is a violent place, and collisions between galaxies are frequent — indeed, the Milky Way is due to crash into the Andromeda Galaxy in a few billion years.

How did Edwin Hubble classify the elliptical galaxies?

Classification and characteristics. In 1926, Edwin Hubble devised a system to classify galaxies. Known as the Hubble sequence, or the “Hubble tuning-fork”, it organizes galaxies based on their shape. Under this organization, elliptical galaxies are classified by how stretched they are.
