Here in Perseus is a minxture of dust, gas and stars that spans about 4 degrees of the sky. The large bright spot in the center is the object NGC 1333 which is a reflection nebula that has been mapped by radio waves. It is one of the closest star forming regions to Earth, at about1,000 light-years away. The red glow in the picture comes from hydrogen gas, and the region is part of a larger molecular cloud that leads scientists to believe that this is a star forming region. These clouds typically hide young stars. This type of "stellar nursuries" are common.
