() type of galaxy with an ellipsoidal shape and no spiral structure. Categorized from E0 (no disk or round to E7 (most elliptical). [The ellipticity is calculated from 10(a-b)/a where a = major axies and b = minor axis.] Other designations include dwarf elliptical ( dE), giant ellipticals () and supergiant ellipticals ( cD).
a cluster of stars and other celestial matter that revolves around a center (often a black hole )
a galaxy in which the stars are concentrated in a central nucleus
a type of galaxy in the hubble sequence characterized by the following physical propert
A galaxy that is round or elliptical in outline, typically containing little gas and dust, and no spiral arms or disk, and few hot, bright stars.
A population II galaxy without spiral arms. M84 and M86 in Virgo are examples of elliptical galaxies.
Ellipsoidal agglomerations of stars outside our galaxy which usually do not contain much interstellar matter. One of the two major types of galaxies, the other being a spiral galaxy.
galaxy with a spherical or oval shape. They are classified as type E and range in shape from type E0 - circular, to type E7 - very elliptical.
Category of galaxy in which the stars are distributed in an elliptical shape on the sky, ranging from highly elongated to nearly circular in appearance.
A galaxy whose structure shaped like an ellipse and is smooth and lacks complex structures such as spiral arms.
A galaxy whose appearance resembles a solid made of a series of ellipses and that contains no conspicuous interstellar material.
A galaxy in which the stars are spread out in a featureless oval distribution. Cygnus A (Elliptical galaxy)
An elliptical galaxy is a galaxy that has the shape of an ellipse. It is also called an "E" or "E-type" galaxy. M87 and M32 are elliptical galaxies.
A galaxy that is round or elliptical in outline. It contains little gas and dust, no disk or spiral arms, and a few hot, bright stars.
a galaxy with a smooth, rounded appearance. Early large burst of star formation long ago used up all of their original gas and dust. Star orbits are aligned in more random directions and have greater eccentricities than star orbits in spiral galaxies.
A galaxy having an elliptical (or near-spherical) shape, some more than others, and composed mostly of old stars and little interstellar matter.
Spherical or oval-shaped galaxy lacking a spiral structure and containing little or no gas and dust.
A galaxy that appears spherical or football-shaped. Elliptical galaxies are comprised mostly of old stars and contain very little dust and 'cool' gas that can form stars.
