What is Andromeda galaxy???????????
Answers
Answer:
Andromeda Galaxy, also called Andromeda Nebula, (catalog numbers NGC 224 and M31), great spiral galaxy in the constellation Andromeda, the nearest large galaxy. The Andromeda Galaxy is one of the few visible to the unaided eye, appearing as a milky blur. It is located about 2,480,000 light-years from Earth; its diameter is approximately 200,000 light-years; and it shares various characteristics with the Milky Way system. It was mentioned as early as 965 CE, in the Book of the Fixed Stars by the Islamic astronomer al-Ṣūfī, and rediscovered in 1612, shortly after the invention of the telescope, by the German astronomer Simon Marius, who said it resembled the light of a candle seen through a horn. For centuries astronomers regarded the Andromeda Galaxy as a component of the Milky Way Galaxy—i.e., as a so-called spiral nebula much like other glowing masses of gas within the local galactic system (hence the misnomer Andromeda Nebula). Only in the 1920s did the American astronomer Edwin Powell Hubble determine conclusively that the Andromeda was in fact a separate galaxy beyond the Milky Way.
