NASA Balloon Mission Tunes in to Radio Mystery - Jan. 7
Cosmic radio noise booms six times louder than expected, according to a new study that includes JPL co-authors Michael Seiffert and Steven Levin. The finding comes from a balloon-borne instrument named the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission, also known as Arcade.
Hubble Finds Stars That 'Go Ballistic' - Jan. 7
