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.
Original - Andromeda Galaxy in infrared, by the Spitzer space telescope. The Andromeda Galaxy is a spiral galaxy 2.5 million light-years away in the constellation Andromeda, making it the nearest spiral galaxy to the Milky Way. The exposure time of this image was 100 sec/pixel, and its scale is 2.8 x 0.8 degrees.
The conclusion was that Andromeda is moving southeast in the sky at less than 0.1 milliarc-seconds per year, corresponding to a speed relative to the Sun of less than 200 km/s towards the south and towards the east. Taking also into account the Sun's motion, Andromeda's tangential or sideways velocity with respect to the Milky Way was found to ...
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.
Gamma Andromedae, Latinized from γ Andromedae, is the third-brightest point of light in the northern constellation of Andromeda. It is a multiple star system approximately 350 light-years from Earth. The system is drifting closer to the Sun with a radial velocity in the range of −12 to −14 km/s. [5]
36 Andromedae is a visual binary star [4] [9] system in the northern constellation of Andromeda. The designation is from the star catalogue of English astronomer John Flamsteed, first published in 1712. It is faintly visible to the naked eye with an apparent visual magnitude of 5.45. [2]
AE And was the brightest star in M31 when it was first noticed during an outburst, at an apparent magnitude around 15, equivalent to an absolute magnitude of −10.2, or around a million times brighter than the Sun. This implies that the outburst may have increased the luminosity of the star, which would be unusual for an LBV.
11 Andromedae, abbreviated 11 And, is a single, [10] orange-hued star in the northern constellation of Andromeda. 11 Andromedae is the Flamsteed designation. It has an apparent visual magnitude of 5.44, [2] which is bright enough to be faintly visible to the naked eye. An annual parallax shift of 11.5 mas [1] yields a distance estimate of 283 ...
