What Is An Elliptical Galaxy Quizlet

Elliptical Galaxy. Spherical (ish) distributions of old stars, no distinct features and no disk, have older stars and little to no current star formation, similar to bulges of spiral galaxies, but larger. Large massive galaxies. the largest and most massive galaxies in the universe are elliptical.

What does an elliptical galaxy contain quizlet?, Elliptical galaxies contain mostly old stars and few new stars form because there is so little free-flowing gas in an elliptical galaxy. Where did the name “irregular” come from? When Hubble first classified galaxies, he had a group of leftovers and he named the irregular. Large spiral galaxies.

Furthermore, What describes an elliptical galaxy?, An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies.

Finally,  What shape do elliptical galaxies have quizlet?, Elliptical galaxies have no arms, however they have a central core, or nucleus (usually a very large black hole.) Stars located in the galaxies are spread out evenly around the core. Elliptical galaxies are not perfect circles but are nearly round.

Frequently Asked Question:

What is a giant elliptical galaxy?

Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they’re frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies.

Elliptical galaxies contain mostly old stars and few new stars form because there is so little free-flowing gas in an elliptical galaxy. Where did the name “irregular” come from? When Hubble first classified galaxies, he had a group of leftovers and he named the irregular. Large spiral galaxies.

What do elliptical galaxies contain?

Elliptical galaxies are ellipsoidal in shape, contain no spiral arms, contain little interstellar gas or dust, and are found mostly in rich clusters of galaxies. Elliptical galaxies appear typically yellow-red, as opposed to spirals which have spiral arms that appear quite blue.

What is an elliptical galaxy quizlet?

Elliptical Galaxy. Spherical (ish) distributions of old stars, no distinct features and no disk, have older stars and little to no current star formation, similar to bulges of spiral galaxies, but larger. Large massive galaxies. the largest and most massive galaxies in the universe are elliptical.

What shape do elliptical galaxies have quizlet?

Elliptical galaxies have no arms, however they have a central core, or nucleus (usually a very large black hole.) Stars located in the galaxies are spread out evenly around the core. Elliptical galaxies are not perfect circles but are nearly round.

What is the description of elliptical galaxy?

: a galaxy that has a generally elliptical shape and that has no apparent internal structure or spiral arms. — called also elliptical. — compare spiral galaxy.

Elliptical galaxies are ellipsoidal in shape, contain no spiral arms, contain little interstellar gas or dust, and are found mostly in rich clusters of galaxies. Elliptical galaxies appear typically yellow-red, as opposed to spirals which have spiral arms that appear quite blue.

What makes up an elliptical galaxy?

Elliptical galaxies are shaped like ellipses (stretched circles). … 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.

How did giant elliptical galaxies get so massive?

Giant elliptical galaxies are generally thought to be the result of galaxy mergers. Ordinary elliptical galaxies may also form in this manner, or may have formed from the gravitational collapse of an interstellar gas cloud.

Can life exist in an elliptical galaxy?

Based on numbers of stars, supernova rates, and metallicity, a prior study concluded that large elliptical galaxies contain up to 10 000 times more habitable planets than the Milky Way and are thus the ‘cradles of life‘.

Why are elliptical galaxies elliptical?

When two spirals collide, they lose their familiar shape, morphing into the less-structured elliptical galaxies. A supermassive black hole is thought to lie at the center of these ancient galaxies. … Born from collision, elliptical galaxies are more commonly found around clusters and groups of galaxies.

What shape is an elliptical galaxy?

As their name suggests, elliptical galaxies are round or oval, with stars distributed fairly uniformly throughout. They have a bulge and halo, like spiral galaxies, but don’t have the flat disk of stars. The stars in ellipticals tend to be older. Irregular galaxies have no identifiable shape or structure to them.

What is an elliptical galaxy quizlet?

Elliptical Galaxy. Spherical (ish) distributions of old stars, no distinct features and no disk, have older stars and little to no current star formation, similar to bulges of spiral galaxies, but larger. Large massive galaxies. the largest and most massive galaxies in the universe are elliptical.

Do elliptical galaxies have a bulge?

Bulges were historically thought to be elliptical galaxies that happened to have a disk of stars around them, but high-resolution images using the Hubble Space Telescope have revealed that many bulges lie at the heart of a spiral galaxy.

How do large elliptical galaxies form quizlet?

-Very distant galaxies appear similar to closer galaxies. –Large elliptical galaxies are formed by mergers. -Collisions between galaxies trigger star formation. -There is evidence that galaxies evolve by collisions and mergers.

What is an elliptical galaxy made of?

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.
