The Most Distant Object Yet Discovered in the Universe

ESO's Very Large Telescope has shown that a faint gamma-ray burst detected last Thursday is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang.

Constelation

In the rosy light of dawn, construction continues on the new lightning protection system for the Constellation Program on Launch Pad 39B at NASA's Kennedy Space Center in Florida. Each of the three new lightning towers will be 500 feet tall with an additional 100-foot fiberglass mast atop. This improved lightning protection system allows for the taller height of the Ares I rocket compared to the space shuttle. Pad 39B will be the site of the first Ares vehicle launch, including the Ares I-X test flight that is targeted for July 2009.

taikonaut

A Chinese taikonaut (Chinese astronaut) today became the first taikonaut to walk in space when he left his space craft for a total of fifteen minutes. The entire event, which marks a new stage in China's space program, was broadcast live on national TV.

The walk started at 1630 local time (0830 UTC) today when he exited the spacecraft, while attached to an umbilical cable. Zhai Zhigang, who has also worked as a fighter pilot, carried out the space walk. "I'm feeling quite well. I greet the Chinese people and the people of the world," he said as he walked out of his spacecraft to start the walk.

Moon Base

Designed by Architects and Vision, MoonBaseTwo is a semi-permanent moon base which allows up to 4 astronauts to live there for 6 months. MoonBaseTwo is designed to be transported by the Ares V rocket. The base automatically deploys after landing and ready to accommodate astronauts.

PS: November 15, 2008 - At 8:34 pm Indian time Friday night (1504 UTC), India became the fourth country to land its flag on the Moon. The unmanned lunar orbiter Chandrayaan-1 (meaning 'Moon craft' in Sanskrit) ejected its Moon Impact Probe, which hurtled across the surface of the Moon at 1.5 kilometres per second (3000 miles per hour), and successfully crash landed near the Moon's south pole. Besides carrying three important scientific instruments, the lunar probe also carried the image of the Indian national flag, painted on all sides.

cocoon

The Cocoon Nebula, cataloged as IC 5146, is a strikingly beautiful nebula located about 4,000 light years away toward the constellation of the Swan (Cygnus). Inside the Cocoon Nebula is a newly developing open cluster of stars. Like other stellar nurseries, the Cocoon Nebula holds, at the same time, a bright red emission nebula, blue reflection nebulas, and dark absorption nebulas. Given different mixtures, these three processes create a host of colors in this image taken recently by the Canada-France-Hawaii Telescope (CFHT) in Hawaii, USA.
Speculation based on recent measurements holds that the massive star towards the left of the picture opened a hole in an existing molecular cloud through which much of the glowing material flows. The same star, which formed about 100,000 years ago, now provides the energy source for much of the emitted and reflected light from this nebula.

we're sustained by the corpse of a fallen constellation

Messier 74 (also known as NGC 628) is a face-on spiral galaxy in the constellation Pisces. The galaxy contains two clearly-defined spiral arms and is therefore used as an archetypal example of a Grand Design Spiral Galaxy. The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. However, the relatively large angular size of the galaxy and the galaxy's face-on orientation make it an ideal object for professional astronomers who want to study spiral arm structure and spiral density waves.

all that dust

The spherical coma of Comet Holmes has swollen to a diameter of over 1.4 million kilometers, making the tenuous, dusty cloud even bigger than the Sun. Scattering sunlight, all that dust and gas came from the comet's remarkably active nucleus, whose diameter before the late October outburst was estimated to be a mere 3.4 kilometers. In this sharp image, recorded on November 14 with the Canada-France-Hawaii Telescope, stars are easily visible right through the outer coma, while the nucleus is buried inside the condensed, bright region. The bright region of the coma seems offset from the center, consistent with the idea that a large fragment drifted away from the nucleus and disintegrated, producing the comet's spectacular outburst. Of course, more recent images of Holmes also show the bright star Mirfak (Alpha Persei) shining through as the comet sweeps slowly through the constellation Perseus.

International Space Station (ISS)

STS-120 Mission - Monday, November 5 (Flight day 14)
The two crews spent the morning preparing for Discovery's undocking from the International Space Station. At 10:32 UTC, the orbiter successfully backed away from the Pressurized Mating Adapter on the Destiny Laboratory, and pilot Zamka began the fly-around to allow the shuttle crew to photograph the new configuration of the station. After performing the final separation burn, focused inspection began, to scan the wing leading edges and nose cap, the final analysis that allows the ground team to clear the orbiter for re-entry on Wednesday.

eclipse

Here is what the Earth looks like during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 kilometers per hour. Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the Sun appears blocked by the Moon. This spectacular picture of the 1999 August 11 solar eclipse was one of the last ever taken from the Mir space station. The two bright spots that appear on the upper left are possibly Jupiter and Saturn, although this has yet to be proven. Mir was deorbited in a controlled re-entry in 2001.
