God is a Wireless Scientist Too !

Listening to the early universe just got harder according to a team, led by Alan Kogut, at NASA's Goddard Space Flight Center in Greenbelt, Md. They discovered cosmic radio noise that booms six times louder than expected. The finding comes from a balloon-borne instrument named ARCADE, which stands for the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission. In July 2006, the instrument launched from NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and flew to an altitude of 120,000 feet, where the atmosphere thins into the vacuum of space. ARCADE's mission was to search the sky for heat from the first generation of stars. Instead, it found a cosmic puzzle. The findings were announced on the 7th january 2009.

"The universe really threw us a curve," Kogut says. "Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted." Detailed analysis ruled out an origin from primordial stars or from known radio sources, including gas in the outermost halo of our own galaxy. The source of this cosmic radio background remains a mystery."

It is these radio scientific break throughs, once we undersatnd them, that may introduce the radio communications of tomorrow.
