The photo was taken by the Hubble Space Telescope and shows a detail of the nebula. This close-up shows a dense cloud of dust and gas, a stellar nursery full of embryonic stars. This cloud is about 8 light-years away from the nebula's central star, not shown in this picture. Located in Sagitarius, the nebula's name means "divided into three lobes".

  Featured Book ~ The Outrageous Tales of a Space Shuttle Astronaut | Mike Mullane
The Outrageous Tales of a Space Shuttle AstronautThe Outrageous Tales of a Space Shuttle Astronaut - On February 1, 1978, the first group of space shuttle astronauts, twenty-nine men and six women, were introduced to the world. Among them would be history makers, including the first American woman and the first African American in space. This assembly of astronauts would carry NASA through the most tumultuous years of the space shuttle program. Four would die on Challenger. Mullane vividly portrays every aspect of the astronaut experience -- from telling a female technician which urine-collection condom size is a fit; to walking along a Florida beach in a last, tearful goodbye with a spouse; to a wild, intoxicating, terrifying ride into space; to hearing "Taps" played over a friend's grave. Mullane is brutally honest in his criticism of a NASA leadership whose bungling would precipitate the Challenger disaster.

 A Great Shot by the Missing Mars Global Surveyor 

Newsletter sent to me today, features a Mars image taken by Mars Global Surveyor (MGS}, which became MGS's picture of the week. As we know it, MGS is now missing from the radar contact for couples days and now two other NASA's spacecrafts currently orbiting Mars are commanded to search for the missing spacecraft.

And here's the latest great shot by MGS and as a MGS's picture of the week,

Image caption: Crisp details in a suite of mid-latitude gullies on a crater wall are captured in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) view obtained in southern winter on 12 October 2006. During southern winter, shadows are more pronounced and the atmosphere is typically quite clear. These gullies, which may have formed in relatively recent martian history by erosion caused by flowing, liquid water, are located in a crater on the east rim of Newton Crater near 40.4°S, 155.3°W. Sunlight illuminates the scene from the upper left. The picture covers an area about 3 km (1.9 mi) wide; the crater rim is on the right side of the image, the crater floor is on the left. North is toward the top/upper left.

 Hubble Finds Evidence for Dark Energy in the Young Universe 

Image Credit: NASA

Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate. Investigators used Hubble to find that dark energy was already boosting the expansion rate of the universe as long as nine billion years ago. This picture of dark energy is consistent with Albert Einstein's prediction of nearly a century ago that a repulsive form of gravity emanates from empty space. Data from Hubble provides supporting evidence to help astrophysicists to understand the nature of dark energy. This will allow them to begin ruling out some competing explanations that predict that the strength of dark energy changes over time.

 ESA's Satellite Images on Google Earth 

Ever wanted to see what volcanic eruptions, dust storms and changing ice glaciers look like from space? The European Space Agency (ESA) has created a special layer of content that will appear in Google Earth, enabling people to see over 130 new ESA satellite images including natural phenomena and manmade landmarks such as the Palm Islands in Dubai.

 One-eyed Monster Storm on Saturn 

Image Credit: NASA

Saturn again amazed the astronomers with its natural secret. Huge hurricane-like storm swirls at its South pole. Big, big storm at 8,000 km across, almost two third the diameter of Earth. Cassini instrument measured its speed about 550 km per hour. It looks oddly like a giant human eye.

 Breathtaking Natural Color View of Saturn's Rings 

Image Credit: NASA

Today I browsed the Cassini mission website and found out that they released new image of the rings in natural color view. Really breathtaking, very sharp, and eye-catching. Photographed on Sept. 29, 2006 at a distance of approximately 1.829 million kilometers (1.137 million miles) from Saturn, it shows the outer B ring, the Cassini Division and the inner part of the A ring.

This ring image color and lines reminded me with my wallpaper design I made sometime in 2003. I named the work "orbzone". A portion of the artwork is almost very much the same as this cassini image, with the effect of the wallpaper design I made in 3dsmax and Photoshop.

 Soon to Come, Mercury Transit! 

People in some parts of the world will have an opportunity to watch a special celestial event this month. Mercury will pass in front the Sun disk on November 8. Mercury, the smallest planet in newly-defined solar system, will cross the Sun starting at 11:12 a.m. (PST) and moving away from the Sun at 4:10 p.m. (PST). The half point of the transit will be at 1:41 p.m. (PST). According to Melanie Knocke of Planetary Society writer, people in North and South America will see at least a portion of the event, the Sun will set before the transit completes. Meanwhile people in eastern Asia, Australia, and New Zealand will start seeing this transit when the Sun rises above the horizon on November 9 and at that moment the transit will be already underway. The transit will be visible in its entirety only for people living in the region of the Pacific Ocean, southern Alaska and along the western coast of the United States. The transit unluckily will not be visible for people in Europe, Africa, western Asia, the Middle East, and India.

Picture below is the Mercury transit on November 15, 1999, and was taken by Transition Region and Coronal Explorer (TRACE) mission.

 Galaxy Cluster Host to Largest Known Radio Eruption 

Image Credit: ESA/NASA

View Larger Size

This is a new composite image of galaxy cluster MS0735.6+7421, located about 2.6 billion light-years away in the constellation Camelopardus. The three views of the region were taken with NASA's Hubble Space Telescope in Feb. 2006, NASA's Chandra X-ray Observatory in Nov. 2003, and NRAO's Very Large Array in Oct. 2004. The Hubble image shows dozens of galaxies bound together by gravity. In Jan. 2005, astronomers reported that a supermassive black hole, lurking in the central bright galaxy, generated the most powerful outburst seen in the universe. The VLA radio image shows jets of high energy particles (in red) streaming from the black hole. These jets pushed the X-ray emitting hot gas (shown in blue in the Chandra image) aside to create two giant cavities in the gas. The cavities are evidence for the massive eruption. The X-ray and radio images show the enormous appetite of large black holes and the profound impact they have on their surroundings.

    The Oort cloud, is a postulated spherical cloud of comets situated about 50,000 to 100,000 AU from the Sun. This is approximately 1000 times the distance from the Sun to Pluto or roughly one light year, almost a quarter of the distance from the Sun to Proxima Centauri, the star nearest the Sun. The Oort cloud would have its inner disk at the ecliptic from the Kuiper belt. Although no direct observations have been made of such a cloud, it is believed to be the source of most or all comets entering the inner solar system (some short-period comets may come from the Kuiper belt), based on observations of the orbits of comets.
