Star-forming region NGC 1333 is located 1,000 light-years away in the constellation Perseus, and is normally enshrouded by thick dust. NASA's Spitzer Space Telescope used its infrared capabilities to pierce this dust layer to reveal the young stars hidden inside. Astronomers are hoping to use Spitzer to spot any nascent planetary structures around these young stars. Now that they're getting going, the young stars are firing out jets of radiation that are steadily clearing the surrounding region of additional dust.
