2023年11月21日 · The formal elliptical galaxy definition is a galaxy that appears elliptical in shape. They are round, smooth collections of stars, unlike the more (swell-known spiral galaxies with awe-inspiring ...

2023年11月21日 · An elliptical galaxy is the most common type of galaxy, has a roundish shape, and demonstrates little or no star formation. An irregular galaxy is a galaxy with no defined shape that has very ...

2023年11月21日 · IC 1101 is a supergiant elliptical galaxy, one of the most giant known galaxies containing ~100 trillion stars with a diameter of possibly 4 million light-years. IC 1101 is a little over a billion ...

The elliptical galaxy NGC 3610 is unusual. Because most elliptical galaxies are old and are formed by collisions of other galaxies, they don't have easy-to-spot shapes like the spiral galaxies do.

A galaxy is a system of stars, combined with dust and gas, and bonded with gravity. Learn about ring and elliptical galaxies, including how they are formed, and explore the possibility of galaxy ...

2023年11月21日 · This elliptical galaxy is large, spherical and classified as an E0 galaxy in the Hubble classification scheme. It is a member of the Virgo cluster of galaxies , which contains over 2,000 galaxies.

Elliptical galaxies actually have more blue stars than spiral galaxies, but they are so bright that they appear white. Elliptical galaxies have lost their dust and gas so they cannot make new stars.

Both elliptical and spiral galaxies have a faint, highly distributed sphere of stars around their main structure called a "halo." They are also believed to have similar halos of invisible dark matter, which comprises the majority of their mass.

What is an elliptical galaxy? A) A galaxy with an elliptical outline and a smooth distribution of brightness (no spiral arms). B) A spiral galaxy seen from an angle, giving it an elliptical profile. C) A spiral galaxy with an elliptically shaped nuclear bulge and the spiral arms starting from the ends of …
