Andromeda galaxy expanded by cannibalizing on stars from other galaxies.Byline: ANI London, September 3 (ANI): A new research has shown that the vast Andromeda galaxy Andromeda Galaxy, cataloged as M31 and NGC 224, the closest large galaxy to the Milky Way and the only one visible to the naked eye in the Northern Hemisphere. It is also known as the Great Nebula in Andromeda. It is 2. appears to have expanded by cannibalizing on stars from other galaxies. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. a report by BBC BBC in full British Broadcasting Corp. Publicly financed broadcasting system in Britain. A private company at its founding in 1922, it was replaced by a public corporation under royal charter in 1927. News, when an international team of scientists mapped Andromeda, they discovered stars that they said were "remnants of dwarf galaxies". This consumption of stars has been suggested previously, but the team's ultra-deep survey has provided detailed images to show that it took place. This shows the "hierarchical model In a hierarchical data model, data are organized into a tree-like structure. The structure allows repeating information using parent/child relationships: each parent can have many children but each child only has one parent. " of galaxy formation in action. The model predicts that large galaxies should be surrounded by relics of smaller galaxies they have consumed. The scientists charted the outskirts of Andromeda in detail for the first time. They discovered stars that could not have formed within the galaxy itself. Pauline Barmby, an astronomer from the University of Western Ontario Western is one of Canada's leading universities, ranked #1 in the Globe and Mail University Report Card 2005 for overall quality of education.[2] It ranked #3 among medical-doctoral level universities according to Maclean's Magazine 2005 University Rankings. told BBC News that the pattern of the stars' orbits revealed their origin. "Andromeda is so close that we can map out all the stars," she said. "And when you see a sort of lump of stars that far out, and with the same orbit, you know they can't have been there forever," she added. Andromeda, which is approximately 2.5 million light years away from Earth is still expanding, say the scientists. The researchers also saw a "stream of stars" of a nearby galaxy called Triangulum "stretching" towards Andromeda. According to Dr Scott Chapman, reader in astrophysics astrophysics, application of the theories and methods of physics to the study of stellar structure, stellar evolution, the origin of the solar system, and related problems of cosmology. at the Institute of Astronomy, University of Cambridge, "Ultimately, these two galaxies may end up merging completely. Ironically, galaxy formation and galaxy destruction seem to go hand in hand." Nickolay Gnedin, an astrophysicist from the University of Chicago, described the work as showing "galactic archaeology in action".
