Some of the coldest and darkest dust in space shines brightly in this
infrared image from the Herschel Observatory, a European Space Agency
mission with important participation from NASA. The image is a composite
of light captured simultaneously by two of Herschel's three instruments --
the photodetector array camera and spectrometer, and its spectral and
photometric imaging receiver.
The image reveals a cold and turbulent region where material is just
beginning to condense into new stars. It is located in the plane of our
Milky Way galaxy, 60 degrees from the center. Blue shows warmer material,
red the coolest, while green represents intermediate temperatures. The red
filaments are made up of the coldest material pictured here -- material
that is slightly warmer than the coldest temperature theoretically
attainable in the universe.
Light captured by the photodetector array camera and spectrometer is
colored blue and green (blue represents 70-micron light, and green, 160
micron light). The light detected by the spectral and photometric imaging
receiver is colored red (and shows the combined wavelengths of 250, 350
and 500 microns). The image spans a region 2.1 by 2.2 degrees.
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. 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. More information about NASA's
role in the mission is at http://www.herschel.caltech.edu/.
