Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across and lies 2.5 million light-years away in the constellation Andromeda. Dense clusters of hot, young, blue stars sparkle in the disk beyond the galaxy's smooth, redder central bulge. Star clusters are especially ...
Andromeda Galaxy. A visible light image of the Andromeda Galaxy. Messier 32 is to the left of the galactic nucleus and Messier 110 is at the bottom right. 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.
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.
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.
Novae have been detected in this galaxy, including one discovered in 1999, and another in 2002. The latter, designated EQ J004015.8+414420, had also been captured in images taken by the Sloan Digital Sky Survey (SDSS) that October. Local context The Andromeda Galaxy and its satellite galaxy, Messier 110, to the bottom-right of the center
38° 40′ 12″. 9.9. M5e-M6e. a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.

Description PIA20061 - Andromeda in High-Energy X-rays, Figure 1.jpg. English: NASA's Nuclear Spectroscope Telescope Array, or NuSTAR, has imaged a swath of the Andromeda galaxy -- the nearest large galaxy to our own Milky Way galaxy. NuSTAR's view (inset) shows high-energy X-rays coming mostly from X-ray binaries, which are pairs of stars in ...
