土星の月「Enceladus」
まるで間欠泉から吹き出る氷の粒子のようだと

Scientists Study The Plumbing Of The Enceladus Plumes
The large number of ice particles observed spewing from the geysers and the steady rate at which these particles are produced require high temperatures, close to the melting point of ice, possibly resulting in an internal lake. The lake would be similar to Earth's Lake Vostok, beneath Antarctica, where liquid water exists locked in ice.

Potsdam, Germany (SPX) Feb 14, 2008
Scientists on the Cassini mission have become out-of-this world "plumbers" as they try to piece together what's happening inside the "pipes" feeding the plumes of Saturn's moon Enceladus. Enceladus is jetting out giant geysers three times the size of the moon, and now scientists are beginning to understand how the ice grains are created and how they might have formed.

Game consoles can model black holes, drug molecules

Paris (AFP) Feb 13, 2008
Researchers are cannibalising the Sony PlayStation 3 console and other gaming hardware, turning them into low-cost supercomputers to model pharmaceutical molecules and black holes, the weekly New Scientist says.

Astronomers Find One Of The Youngest And Brightest Galaxies In The Early Universe
NASA's Hubble and Spitzer space telescopes, with a boost from a natural "zoom lens," have uncovered what may be one of the youngest and brightest galaxies ever seen in the middle of the cosmic "dark ages," just 700 million years after the beginning of our universe.

Rubik's Cube In Center Of Earth? Computer Simulations Support New Model Of Earth's Core
Swedish researchers have presented evidence to support their new theory about the structure of the earth's core. The findings may be of significance for our understanding of the cooling down of the earth, and of the stability of the earth’s magnetic field. "We found that the body-centered cubic structure of iron is the only structure that could correspond to the experimental observations," says Brje Johansson, professor of condensed-matter theory at Uppsala University.

Lightweight Disk Could Harbour Planets
Astronomers are looking for planets around other stars, but they're also looking for the conditions where planets might be forming right now. Inside the disks of material that surround newly forming planets, they could be planets clearing paths through all the gas and dust. A team of Japanese astronomers have found the most lightweight stellar disk ever seen - a place where Earth-sized planets could be forming.

"Listening" for Gravitational Waves to Track Down Black Holes
Gravitational waves are predicted by Einstein's 1916 general theory of relativity, but they are notoriously hard to detect and it's taken many decades to come close to observing them.
