is andromeda a barred spiral galaxy

In 1939, Horace W. Babcock reported the rotation curve for the Andromeda nebula (known now as the Andromeda Galaxy), which suggested the mass-to-luminosity ratio increases radially. Known to the ancient Babylonians and Greeks, Triangulum was one of the 48 constellations listed by the 2nd century astronomer Ptolemy. They have an orbital period of 17 years. Its first appearance in the pre-dawn sky (heliacal rising) in February marked the time to begin spring ploughing in Mesopotamia. The ShapleyCurtis Debate opened up different ideas and possibilities of the nature of the universe. Milky Way Galaxy The normal spirals are designated S and the barred varieties SB. A barred spiral galaxy stretching 100,000 light-years across. They come in a variety of shapes and sizes. Observations show that stars on both galaxies halos are metal-poor.

Where is Earth in the Milky Way It is classified as SB(s)b, which means that its spiral arms wind moderately around the prominent central bar. Studies also indicate that because galaxies are mostly empty space, it is unlikely for stars to collide with each other. The more commonly used name, Asellus Australis, means southern donkey colt in Latin.

Also, the distortion of its spiral arms is probably because of its interactions with its satellite galaxies Messier 32 and Messier 110. GALAXIES Milky Way Galaxy It is about 2.5 million light years away from us, but its getting closer, and researchers predict that in about 4 billion years it will collide with the Milky Way. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area. |Score 1|emdjay23|Points 162446| User: Large groups of galaxy clusters that appear in sheetlike and threadlike shapes are known as A. local clusters. This is because Andromeda is approaching our way at a rate of 110 kilometers per second (68 mi/sec).

The other galaxies are even further away from us and can only be seen through telescopes. The French astronomer Guillaume Le Gentil discovered this satellite galaxy in 1749. These two nuclei are 4.9 light-years away from each other. King Cepheus became very worried so he consulted the Oracle of Ammon. The Two Micron All-Sky Survey (2MASS) and the Spitzer Space Telescope both reveal that the Andromeda Galaxy has a barred spiral structure. The star is also notable for its less famous name, Arkushanangarushashutu, which is the longest of all the known star names. Its diameter is around 220,000 light-years and its mass equals the mass of 1,230 billion Suns!

The Andromeda Galaxy (IPA: / n d r m d /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy approximately 2.5 million light-years (765 kiloparsecs) from Earth and the nearest large galaxy to the Milky Way Baily also noted that 16 Trianguli was closer to Aries and included it in the latter constellation. Located in the Andromeda constellation, it is the closest spiral galaxy to the Milky Way, where our solar system is, although it isn't the closest overall galaxy to the Milky Way. The two orbit around a common centre of gravity every 31 days, and are surrounded by a ring of dust that extends from 50 to 400AU away from the stars.

It lies in the second quadrant of the northern hemisphere (NQ2) and can be seen at latitudes between +90 and -60.

[16] Lying near Gamma and forming an optical triple system with it are Delta and 7 Trianguli. It lies 2.58 million light-years from us. In Greek mythology, the constellation Cancer is associated with the crab sent by Hera to defeat Heracles. Andromeda Galaxy is the closest spiral galaxy to the Milky Way and the farthest object in the night sky visible to the unaided eye. But who is she in Greek mythology? Also, it remains the only supernova event that was ever observed in the Andromeda Galaxy. Hiu ng ny ging nh "sng" di chuyn chm li dc theo ng cao tc cha y t.
