Spitzer telescope discovers enormous asteroid belt.
NASA's Spitzer space telescope has discovered an enormous asteroid belt orbiting another star, containing 25 times as much material as the belt in our Solar System. If we had an asteroid belt this thick, it would light up the night sky in a bright band. Once confirmed, this will be the first asteroid belt found orbiting a star similar to our own Sun. Another possibility is that Spitzer is seeing a Pluto-sized Comet which has been orbiting the star for many years and has left a bright trail of particles.
NASA's Lunar Prospector hinted at the possibility that there are pockets of water ice in permanently shadowed craters at the Moon's poles. These reservoirs of water would be and invaluable supply of drinking water and air for astronauts, as well as the raw material for propellants. scientists just need to confirm that it's there. NASA will be sending a new spacecraft, the Lunar Reconnaissance Orbiter, in 2008. It'll have four separate instruments capable of detecting water. So, we might know the answer soon.
Physicists with MIT have reported the discovery of a new state of matter - a perfect liquid - which was probably present in the earliest moments after the Big Bang. The team smashed atoms together in the Relativistic Heavy Ion Collider, creating a plasma that lasted for only an instant. The particles in the plasma have the same properties as a liquid; they cling together and move in a pattern, but they would flow much more easily than water if they could be poured.
