The 'Terrible Twos'
Young stars, like toddlers, want to start showing their independence. This Spitzer view shows a stellar version of the "terrible twos" -- the stars are beginning to move away from their formative cloud, seen in red and green. Jets can be seen coming off the young stars as they make their way into the cosmos.
Located 1,000 light-years from Earth in the constellation Perseus, the reflection nebula NGC 1333 epitomizes the beautiful chaos of a dense group of stars being born.
