reflection nebula NGC 1333 Chaotic Star Birth
Located 1,000 light-years from Earth in the constellation Perseus, a reflection nebula epitomizes the beautiful chaos of a dense group of stars being born.

In this infrared view, one group of young stars is seen in red to the north near the nebula. The other group is south, where the features shown in yellowish green abound. With the sharp infrared eyes of Spitzer, scientists can detect and characterize the warm and dusty disks of material that surround forming stars.
