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 ...
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 ...
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 ...
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.
Unlike a spiral or elliptical galaxy, irregular galaxies lack a distinct structure or shape. They are thought to make up about a quarter of all galaxies. Most irregular galaxies were once spiral ...
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.
This huge elliptical galaxy (center) is home to older stars bunched together. Spiral Galaxies Spiral galaxies have centers with bands or arms coming out from the center in a spiral formation ...
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.
The following is the optical spectrum of an elliptical galaxy. \The rest wavelength of the sodium-D (Na D) absorption line is 5890 Angstroms. What is the velocity of this galaxy, and is it moving towards or away from us? The speed of light, c, is 3x105 km/s. The following is the optical spectrum of an elliptical galaxy.
