Herschel Sees Through Ghostly Pillars

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. 

Herschel 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. 

Herschel is a European Space Agency cornerstone mission, with science instruments provided by consortia of European institutes and with important participation by NASA. NASA's Herschel Project Office is based at NASA's Jet Propulsion Laboratory, Pasadena, Calif. JPL contributed mission-enabling technology for two of Herschel's three science instruments. The NASA Herschel Science Center, part of the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena, supports the United States astronomical community. Caltech manages JPL for NASA.
