Orion Nebula in Infrared NASA ID: PIA25434 This new image of the Orion Nebula produced using previously released data from three telescopes shows two enormous caverns carved out by unseen giant stars that can release up to a million times more light than our Sun. All that radiation breaks apart dust grains there, helping to create the pair of cavities. Much of the remaining dust is swept away when the stars produce wind or when they die explosive deaths as supernovae. This infrared image shows dust but no stars. Blue light indicates warm dust heated by unseen massive stars. Observed in infrared light ? a range of wavelengths outside what human eyes can detect ? the views were provided by NASA's retired Spitzer Space Telescope and the Wide-Field Infrared Survey Explorer (WISE), which now operates under the moniker NEOWISE. Spitzer and WISE were both managed by NASA's Jet Propulsion Laboratory in Southern California, ...more 508 Description:This infrared image of the Orion Nebula features plenty of dust but no stars. In these infrared wavelengths, it's possible to see hot spots where new stars are forming, while unseen bright, massive stars have carved out caverns of empty space.
