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 ...

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.

An elliptical galaxy is a galaxy classification used in the Hubble Classification System. Discover what classifies as an elliptical galaxy by exploring the definition, examples, and facts on the ...

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.

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 ...

2. Even though elliptical galaxies are the most common type in the galaxy, astronomers have identified and named more spiral galaxies than elliptical galaxies.

This is supported by the fact that stars in elliptical galaxies are redder, suggesting they are older. Answer and Explanation: 1 An elliptical galaxy looks as if it is a giant star because it lacks the distinctive structure of a spiral galaxy, where the bulge is surrounded by a...

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.
