"This graphic represents a slice of the spider-web-like structure of the universe, called the "cosmic web." These great filaments are made largely of dark matter located in the space between galaxies. "

"ABOUT THIS IMAGE:
This illustration shows how the Hubble Space Telescope searches for missing ordinary matter, called baryons, by looking at the light from quasars several billion light-years away. Imprinted on that light are the spectral fingerprints of the missing ordinary matter that absorbs the light at specific frequencies (shown in the colorful spectra at right). The missing baryonic matter helps trace out the structure of intergalactic space, called the "cosmic web.""

"It is kind of like a spider web. The gravity of the spider web is what produced what we see," Shull said in a telephone interview. "It's very thin. Some of it is very hot gas, almost a million degrees."

Bulk of Missing "Normal" Matter Found in Cosmic Web
"The researchers found evidence that about 40 percent of the missing baryonic matter is concentrated around filaments that crisscross the intergalactic medium."

More missing cosmic matter found - USATODAY.com
"Astronomers have long known that the amount of matter we can see doesn't match up with what's actually there. Normal matter (which includes galaxies, stars and us) makes up only about 4% of the universe. This type of matter is also called "baryonic" because it is made of baryons (protons, neutrons and other subatomic particles).
The missing part of baryonic matter has largely escaped detection because it is too hot to be seen in visible light but too cool to be seen in X-rays. Dubbed the "intergalactic medium," or IGM, it extends essentially throughout all of space like a cosmic spider web.
(This missing matter is not to be confused with dark matter, an exotic form of matter that can only be detected by its gravitational pull.)"

COROT
"COROT has now been operating for 510 days, and the mission started observations of its sixth star field at the beginning of May this year. During this observation phase, which will last 5 months, the spacecraft will simultaneously observe 12 000 stars.
The two new planets are gas giants of the hot Jupiter type, which orbit very close to their parent star and tend to have extensive atmospheres because heat from the nearby star gives them energy to expand.
COROT was launched atop the Soyuz from the Baikonour cosmodrome in Kazakhstan on 27 December 2006. Settled in its almost-circular polar orbit ranging between 895 and 906 km above Earth's surface, the spacecraft was first powered on 2 January 2007 and started its science observations on 3 February of the same year.
COROT is a CNES project with ESA participation. The other major partners in this mission are Austria, Belgium, Brazil, Germany and Spain." Exoplanet Hunt Update - Space - redOrbit

Global Monitor Finds No Radioactive Leaks in Quake Zone - New York Times: May 22, 2008
A global network of sensors has found no evidence that China’s complex of nuclear facilities in the earthquake zone let any radioactivity escape, its operator reported Wednesday."

1.
China’s main complex for making nuclear warhead fuel, codenamed Plant 821, is beside a river in a hilly, forested part of the earthquake zone. It is some 15 miles northwest of Guangyuan in Sichuan Province. The vast site holds China’s largest production reactor and factories that mine its spent fuel for plutonium ― the main ingredient for modern nuclear arms.
China was expanding its nuclear forces to 240 warheads in its overall stockpile from around 200.Reactors are usually rigged to shut down in an earthquake, and it is unclear if the Plant 821 reactor could undergo the same kind of disaster that struck the Chernobyl reactor in 1986. It spewed radioactivity across large parts of Russia and Europe.
2.
Closer to the epicenter of the quake that struck Monday is Mianyang, a science city whose outskirts house the primary laboratory for the design of Chinese nuclear arms. It is considered the Chinese equal to Los Alamos. Known as the Chinese Academy of Engineering Physics, it too, Mr. Stillman said, houses a reactor, though a smaller one meant for research.In China, the academy leads in the research, development and testing of nuclear weapons and has centers throughout Sichuan Province.
3.
North of the city, for example, is a plant that shapes plutonium into the compact spheres that ignite nuclear weapons.
4.
Nuclear experts said that closer to the epicenter of the earthquake, in rugged hills a two-hour drive west of Mianyang, China runs a highly secretive center that houses a prompt-burst reactor. It mimics the rush of speeding subatomic particles that an exploding atom bomb spews out in its first microseconds.
5.
North in an even more rugged and inaccessible region, nuclear experts said, China maintains a hidden complex of large tunnels in the side of a mountain where it stores nuclear arms.
