Groups in the Coma dwarf galaxies found in thousands of.

<P Align=center> </ P> World Scientific reports [tech.] News: Beijing June 3, according to NASA's Space Network NASA's Spitzer Space Telescope has been in the Coma .Mission to detect more than a thousand previously unknown dwarf galaxies, these galaxies about 320 million light years from Earth. .Although compared with the larger galaxies seem small, but the evolution of dwarf galaxies in the universe plays a key role. .<P Align=left> astronomers believe that they are the earliest galaxies formed, in order to provide building materials larger galaxies. .They are also the largest number of galaxies around: in fact, computer simulations show that, compared astronomers have observed large clusters of galaxies should have more dwarf galaxies. .</ P> <P align=left> to find thousands of "missing" galaxies, located in Greenbelt, Maryland, NASA Goddard Space Flight Center astronomers will come from the Spitzer Space Telescope .288 film pieces together. .Each film exposure of about 70-90 seconds, and from the "Sloan Digital Sky Survey" of the image data combined to form a huge cover 1.3 square degrees of the sky mosaic. .Although only a small part of the sky, but the team is still in a relatively short period of time that almost 3 million new objects. .Let the team was surprised that most of these new objects proved to be Coma, not the galaxies outside the galaxy. .</ P> <P align=left> Goddard Space Flight Center, an astronomer Lizhanjinsi estimates that about 1,200 objects are dim dwarf planet than previously recognized that the number of dwarf planets produce more lot. .Zhanjin Si said: "We can observe a sudden thousands of dark galaxies, these galaxies that we have not seen before." The team of the Coma Research Group details published in the latest issue of "Astrophysical Journal ."on. .</ P> <P align=left> so astronomers is how to find these faint galaxies it? .The universe emit a lot of visible light, so that we can see the stars with the naked eye. .But most of the human eye from space just can not see, which is why can "see" the infrared Spitzer Space Telescope helped astronomers study the universe in a fully found some will be new. .</ P> <P align=left> the team may have discovered thousands of new celestial bodies, but they said there may be other hidden Coma dwarf galaxies in the Spitzer Space Telescope data. .Can see into the universe through the use of a more deep space telescope, astronomers are now trying to identify the number of dark objects in the end belong to the Coma cluster of galaxies. .</ P> </ p>.
