The star-forming region NGC 1333 contains dozens of new stars like the Sun but less than 1 million years old. Spitzer's IRAC camera reveals those stars, as well as warm dust glowing red and bright green shock fronts in this color-coded infrared image. Credit: NASA/JPL-Caltech/R. Gutermuth & A. Porras (CfA)

At visible wavelengths, much of NGC 1333 is obscured by clouds of gas and dust. One bright star at the top manages to shine forth, lighting the surrounding nebula blue with scattered light. Credit: Jay Lavine and Ali Huang/Adam Block/NOAO/AURA/NSF
