Hubble snaps a pic of a microwave-emitting galaxy
The Hubble telescope team is ending the year with a photo of an unusual galaxy, one that emits microwaves instead of visible light. See that image above? That's a snapshot of IRAS 16399-0937, a "megamaser" 370 million light-years away from Earth. Megamaser galaxies are intense and are around 100 million times brighter than the microwave-emitting areas -- or masers, found in star-forming regions -- of the Milky Way.
