Andromeda Galaxy is the nearest major galaxy to the Milky Way, located in the constellation of Andromeda. It is a barred spiral galaxy with a diameter of about 152,000 light-years and a mass of 1 trillion solar masses.
For example, the nearest star to the Earth after the Sun is Proxima Centauri, about 4.2 light-years (4.0 × 10 13 km; 2.5 × 10 13 mi) or 30 million (3 × 10 7) solar diameters away. To visualize that scale, if the Sun were a ping-pong ball , Proxima Centauri would be a pea about 1,100 km (680 mi) away, and the Milky Way would be about 30 ...
Messier 32 is a compact elliptical galaxy and a satellite of the Andromeda Galaxy. It has a supermassive black hole, a faint outer disk, and a complex formation history.
NGC 891 is an edge-on spiral galaxy in the constellation Andromeda, similar to the Milky Way. It has a dusty disk, a central bar, and a history of supernova explosions.
The Andromeda Galaxy with M110 at upper left and M32 to the right of the core. The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way.Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope.
Mayall II, also known as NGC-224-G1, SKHB 1, GSC 2788:2139, HBK 0-1, M31GC J003247+393440 or Andromeda's Cluster, is a globular cluster orbiting M31, the Andromeda Galaxy. It is located 130,000 light-years (40 kpc) [3] from the Andromeda Galaxy's galactic core, and is the brightest [3] (by absolute magnitude) globular cluster in the Local Group ...
Andromeda is a large constellation in the northern sky, named for the mythological princess who was chained to a rock by a sea monster. It contains the Andromeda Galaxy, the closest spiral galaxy to the Milky Way, and several bright stars and nebulae.
NGC 828 is a spiral galaxy in the constellation of Andromeda. Its velocity with respect to the cosmic microwave background is 5118 ± 17 km/s, which corresponds to a Hubble distance of 75.49 ± 5.29 Mpc (∼246 million light-years). [1] It was discovered by German-British astronomer William Herschel on 18 October 1786. [2]
