Infrared image from NASAs Spitzer Space Telescope showing the Rosette nebula, a pretty star-forming region more than 5,000 light-years away in the constellation Monoceros. lurking inside this delicate cosmic rosebud are so-called planetary danger zones (see spheres illustrations in figure 1). These zones surround super hot stars, called O-stars (blue stars inside spheres), which give off intense winds and radiation. Young, cooler stars that just happen to reside within one of these zones are in danger of having their dusty planet-forming materials stripped away. This image shows infrared light captured by Spitzers infrared array camera. Light with wavelengths of 24 microns is red; light of 8 microns is green; and light of 4.5 microns is blue.
