40 billion years ago, the radius of the galaxy 15 million light years demise of star formation flow.

The flow from the giant star at least 40 million years ago .its destruction of a dwarf galaxy formation. research team, said the dwarf galaxies of stars, star clusters and dark matter in the form of loss of most of the quality. All of these are around in its orbit around the end of the NGC 5907 form a complex cross " .galaxy fossil "collection," fossil galaxies "radius of up to 15 million light years. </ P> <P> Spain Canary researcher at the Institute of Astrophysics, the research team responsible for this observation, said David Martinez .: "Our observations appear to understand the spectacular surrounding spiral galaxies provides a new perspective of astronomical phenomena. halo contains 'fossil dwarf galaxies', similar to the Milky Way for us to study the final stages of galaxy formation provide a unique opportunity." Astronomy .Find trip home and did not find the main galaxies being swallowed objects, so they concluded that this galaxy has been completely destroyed. Martinez said: "These stars flow hard to detect, contain very low density of stars .. This density gives them a terrible feeling. If the death and linked dwarf galaxies, they may be called galaxies have now been swallowed up the ghost. "reported tech.icxo.com World Scientific .</ P> <P> in the observation process, the research team also found that the galaxy NGC 4013, another huge flow of slender ring of stars. NGC 4013 in Ursa Major, nearly 50 million light-years from Earth. This .flow out from the center of a star like the ghost of the tail length of more than 80,000 light years, from old metal-poor stars. Although it is not clear three-dimensional structure, but may be related to the constellation Unicorn "Star Stream" very similar, .that the "Star Stream" is a galaxy of stars around a ring, from 30 billion years ago, the destruction of a dwarf galaxy formation. </ P> <P> theoretical astrophysicist at the University of Victoria, Canada, the team members Yuege Pa .Erlu Shakespeare flow model is good at creating stars. Parr Rubbia said: "The flow of these stars to match the theoretical model allows us to reproduce their history, and describes one of the most mysterious and also the most controversial components of galaxies - .- dark matter. "</ P> <P> Martinez said the search and detection in order to complete the work flow of stars, the team invited to join the famous celestial photographer 杰伊贾巴尼. to obtain images in the process, Jia .Barney's help played a decisive role. the fact that once again proved that amateurs can make a significant contribution to astronomical research. Over the years, Jia Bani in New Mexico and Australia will use a small automatic telescope spectacular color images of deep space. His .picture was published in the world's most popular astronomy magazine. Guba Ni's performance in this observation proved that amateur astronomers can make the 21st century, the potential contribution of astronomical research. In the help of new technology, their ability to compete .intense international research projects. World Scientific reports tech.icxo.com </ P> </ p>.
