PIA15260 - This Herschel image of the Eagle nebula shows the self-emission of the intensely cold nebula's gas and dust as never seen before. Each color shows a different temperature of dust, from around 10 degrees above absolute zero (10 Kelvin or minus 442 degrees Fahrenheit) for the red, up to around 40 Kelvin, or minus 388 degrees Fahrenheit, for the blue.
The Herschel Space Telescope reveals the nebula's intricate tendril nature, with vast cavities forming an almost cave-like surrounding to the famous pillars, which appear almost ghostly in this view. The gas and dust provide the material for the star formation that is still under way inside this enigmatic nebula.
Far-infrared light has been color-coded to 70 microns for blue and 160 microns for green using the Photodetector Array Camera, and 250 microns for red using the Spectral and Photometric Imaging Receiver.
This image combines data from almost opposite ends of the electromagnetic spectrum. Herschel captured longer-wavelength, or far, infrared light, and the space telescope XMM-Newton imaged X-rays. The X-ray data show the hot young stars in the center of the cloud, which are sculpting and interacting with the surrounding ultra-cool gas and dust, seen in infrared. Both wavelengths would be blocked by Earth's atmosphere, so space telescopes such as these are critical to our understanding of the life cycle of stars.
