An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, [1] along with spiral and lenticular galaxies.
Jan 9, 2019 · An elliptical galaxy, full of dark lanes of gas, likely formed in the merger of two other galaxies. Elliptical galaxies host less (or no) star birth than spiral galaxies like the Milky...
X-ray Satellite XMM-Newton Sees ‘Space Clover’ in a New Light.
Dec 5, 2012 · Elliptical galaxies are among the largest single star systems in the cosmos and preserve a long history of galactic collisions. Housing up to a trillion suns, they may even provide a peek into...
Elliptical galaxies have shapes that range from completely round to oval. They are less common than spiral galaxies. Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or structure.
May 9, 2022 · What Is an Elliptical Galaxy? Elliptical galaxies have an even, ellipsoidal shape. They typically contain a much greater proportion of older stars than spiral galaxies do. Four classes are used to classify galaxies: spiral; barred spiral; elliptical and irregular.
Apr 13, 2024 · Elliptical galaxies are one of the three main types of galaxies in the universe, along with spiral and irregular galaxies. They are named for their elliptical shape, which is different from the spiral arms of spiral galaxies. Elliptical galaxies are composed mostly of older stars, gas, and dust, and are typically found in galaxy clusters.
Elliptical galaxies have a smooth ellipsoidal or spherical appearance, and they have far less structure than spiral galaxies do. Elliptical galaxies are typically found in galaxy clusters.
Mar 23, 2008 · Like dust bunnies that lurk in corners and under beds, surprisingly complex loops and blobs of cosmic dust lie hidden in the giant elliptical galaxy NGC 1316.
Compared to other types of galaxies, elliptical galaxies have smaller portions of gas and dust, contain older stars, and don’t form many new stars. The largest and rarest of these galaxies – known as giant ellipticals – are about 300,000 light-years across.
