This image shows the Rho Ophiuchi star-forming region in infrared light, as seen by NASA’s Wide-field Infrared Explorer (WISE). Blue and cyan represent light emitted at wavelengths of 3.4 and 4.6 micrometers, which is predominantly from stars. Green and red represent light from 12 and 22 micrometers, respectively, which is mostly emitted by dust.
