A team led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., today announced the discovery of 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 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. Many objects in the universe emit radio waves. In 1931, American physicist Karl Jansky first detected radio static from our own Milky Way galaxy. Similar emission from other galaxies creates a background hiss of radio noise. The problem, notes team member Dale Fixsen of the University of Maryland at College Park, is that there don't appear to be enough radio galaxies to account for the signal ARCADE detected. "You'd have to pack them into the universe like sardines," he says. "There wouldn't be any space left between one galaxy and the next." The sought-for signal from the earliest stars remains hidden behind the newly detected cosmic radio background. This noise complicates efforts to detect the very first stars, which are thought to have formed about 13 billion years ago -- not long, in cosmic terms, after the Big Bang. Nevertheless, this cosmic static may provide important clues to the development of galaxies when the universe was less than half its present age. Unlocking its origins should provide new insight into the development of radio sources in the early universe. "This is what makes science so exciting," says Michael Seiffert, a team member at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "You start out on a path to measure something -- in this case, the heat from the very first stars -- but run into something else entirely, something unexplained." Interesting My crazy christian self in some way wants to believe that it's the opening of Heaven's Gates in preparation of the return of our Lord and Savior Jesus Christ. lol Link to comment Share on other sites More sharing options...

Guest Posted January 13, 2009 Share Posted January 13, 2009 There is no sound in outer space (no air to conduct the sound waves). RF Link to comment Share on other sites More sharing options...

Planets and stars are known to emit radio waves which can be converted to sound recordings. So, who knows what it is, but it is interesting.

Don't remember the percentage, but visible light, as it's called, is a narrow band compared to the entire specrum. Link to comment Share on other sites More sharing options...
