Mystery Roar Detected From Faraway Space By Andrea Thompson LONG BEACH, Calif. — Space is typically thought of as a very quiet place. But one team of astronomers has found a strange cosmic noise that booms six times louder than expected. The roar is from the distant cosmos. Nobody knows what causes it. Of course, sound waves can't travel in a vacuum (which is what most of space is), or at least they can't very efficiently. But radio waves can. Radio waves are not sound waves, but they are still electromagnetic waves, situated on the low-frequency end of the light spectrum. Many objects in the universe, including stars and quasars, emit radio waves. Even our home galaxy, the Milky Way, emits a static hiss (first detected in 1931 by physicist Karl Jansky). Other galaxies also send out a background radio hiss. But the newly detected signal, described here today at the 213th meeting of the American Astronomical Society, is far louder than astronomers expected. There is "something new and interesting going on in the universe," said Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md. A team led by Kogut detected the signal with a balloon-borne instrument named ARCADE (Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission). In July 2006, the instrument was launched from NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and reached an altitude of about 120,000 feet (36,500 meters), where the atmosphere thins into the vacuum of space. ARCADE's mission was to search the sky for faint signs of heat from the first generation of stars, but instead they heard a roar from the distant reaches of the universe. "The universe really threw us a curve," Kogut said. "Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted." Detailed analysis of the signal ruled out primordial stars or any known radio sources, including gas in the outermost halo of our own galaxy. Other radio galaxies also can't account for the noise — there just aren't enough of them. "You'd have to pack them into the universe like sardines," said study team member Dale Fixsen of the University of Maryland. "There wouldn't be any space left between one galaxy and the next." The signal is measured to be six times brighter than the combined emission of all known radio sources in the universe. For now, the origin of the signal remains a mystery.

interesting but to long we can not know what else is out there I admit.
2 :
Extraterrestrial advanced life hopefully but most likely a new type of universal phenomena.
3 :
God spoke the world into existence.

I think that for now 'the origin of the signal remains a mystery' But thanks for the tip.
5 :
It makes me think that original assumptions have been challenged, therefore more questions need to be asked and more data collected
6 :
Seeing as 'we' don't know, the obvious answer must be GODDIDIT. ~

I bet you have more than 50 "It the voice of God" before the day ends. Just wait until Hugo take that as prof, he'll have a field day and probably proclaims itself as the new prophet.

Don't know but I can't wait until they research it further and find out!
9 :
Good, maybe it will increase and broadcast on the same frequency as that annoying Country Radio station I am totally sick of listening to as I scan the frequencies... hahaha!
10 :
Sounds like the creation of another universe.

It's probably hooligan aliens cruising in their spaceship playing their rap music too loud.
