The diffuse glow reveals the widespread cold reservoir of raw material that our Milky Way galaxy has in stock for building stars. Large-scale turbulence from the giant colliding galactic flows causes this material to condense into the web of filaments seen in this image. As the stellar material becomes colder and denser, gravitational forces take over and fragment these filaments into chains of stellar embryos that can finally collapse to form baby stars. These scientific results from the European Space Agency's Herschel infrared space observatory are revealing previously hidden details of star formation. New images show thousands of distant galaxies furiously building stars and beautiful star-forming clouds draped across the Milky Way. One image captures an ‘impossible’ star in the act of formation. Presented on May 6, 2010, during a major scientific symposium held at ESA, the results challenge old ideas of star birth, and open new roads for future research. http://www.nasa.gov/ | |
