Background Infrared Mysteries Partially Revealed

The BLAST (Balloon-borne Large-Aperture Sub-millimeter Telescope) project led by Mark Devlin of the University of Pennsylvania collected data 120,000 feet above Antarctica, enabling researchers to peer into the distant universe at wavelengths nearly unattainable from the ground.

Those "starburst" galaxies, 7 billion-10 billion light-years from Earth, were thought to make up the Far Infrared Background discovered by satellite.
