Equivalent to 100,000 new neighbor galaxy brightness of the sun.
<P> To participate, "Sloan Digital Sky measurements," 8 astronomers observing programs reported that they found the Milky Way's two new "neighbors." .This finding of known dwarf galaxies around the Milky Way the number increased to 14. .</ P> <P> the two newly discovered dwarf spheroidal galaxies are dwarf galaxies, the stars are located in the constellation Canes Venatici and Bootes in which direction are about 64 million light years away from the sun. .</ P> <P> some astronomers speculate that the Milky Way may also exist around the hundreds of such dwarf galaxies, their "shelter" in the so-called dark matter clumps in the slow rotation around the galaxy. .Although these dwarf galaxies are the Milky Way's nearest neighbor, but because of its brightness is too small, not easy to find them. .</ P> <P> According to experts, the brightness of a galaxy less than 10% of the Milky Way, to be considered dwarf galaxies, and the brightness of galaxies mainly related to the number of stars in galaxies. .Bootes the direction of the newly discovered dwarf galaxy is by far the most dim dwarf galaxies known, but the brightness of the sun, or the equivalent of 100,000. .</ P> <P> "Measurement of the Sloan Digital Sky" observation programs, is one of several national museums, universities and other astronomical research institutions of a global association of the operation of a project to draw about the final Star Chart .detailed images of a quarter of the celestial bodies, for scientists to use. .</ P> <P align=center> Milky Way </ P> <P align=center> </ P> <P align=center> </ P> <P> </ P> </ p>.
