The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31 , M31 , and NGC 224 . Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years ) [8] and is approximately 765 kpc (2.5 million light-years ...
Andromeda (Weyes Blood song) " Andromeda " is a song recorded by American singer-songwriter Weyes Blood, released through Sub Pop on January 17, 2019, as the lead single from her fourth studio album Titanic Rising (2019).

The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
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. The second-brightest and closest one to M31 is M32. The other galaxies are fainter, and were mostly discovered starting from the 1970s.
Apparent size (V) 13′.5 × 2′.5 [1] Other designations. UGC 1831, PGC 9031, [1] Caldwell 23. NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6 ...
PA-99-N2 is a microlensing event detected in the direction of the Andromeda Galaxy in 1999. Explanations. One possibility for the event is that a star in the disk of M31 gravitationally lensed a red giant also in the disk. The lensing star would have a mass between 0.02 M ☉ and 3.6 M ☉ with the most likely value near 0.5 M ☉.
SN 1885A. SN 1885A (also S Andromedae) was a supernova in the Andromeda Galaxy, the only one seen in that galaxy so far by astronomers. It was the first supernova ever seen outside the Milky Way, [3] though it was not known at the time how far away it was. It is also known as "Supernova 1885".
Description Andromeda galaxy Ssc2005-20a1.jpg. English: NASA's Spitzer Space Telescope has captured stunning infrared views of the famous Andromeda galaxy to reveal insights that were only hinted at in visible light. This Spitzer's 24-micron mosaic is the sharpest image ever taken of the dust in another spiral galaxy.
