The Week in Space

(Spaceflightnow, Mar. 27, 2010) — "VSS Enterprise" takes flight, and "space for the rest of us" moves a step forward. The Martian Rite of Spring commences, while the folks at JPL in Pasadena prep a "rover on steroids" for departure to the Red Planet. The Wizard Nebula is ready for its close-up, there's Roller Derby on Saturn's rings, Discovery is "go" for launch with orbital Olympics. And the crew of STS-134 prepares to go where no one has gone before. Finally, Buzz "Twinkle-Toes" Aldrin wows the judges on "Dancing with the Stars" -- or not.

Hand of God in Space

NASA Chandra X-ray nebula (NASA)

We've already seen pictures of the eye of God [in Buddhist terms, Maha Brahma]. Now we have the first image of the hand. A ghostly blue cloud seems to form an outstretched thumb and fingers grasping a ball of fire.

The amazing image was taken by NASA's Chandra X-ray observatory, which is orbiting 580km above the Earth. It recalls pictures of the Helix planetary nebula, with its blue center surrounded by white clouds, which earned it the nickname "the eye of God."

The hand was created when a star exploded in a supernova, creating a rapidly spinning 20km-wide star called a pulsar, which is deep inside the white blob at the hand's wrist.

The pulsar is spewing out enormous amounts of electromagnetic energy, creating a dust and gas cloud so wide it would take 150 years to cross at the speed of light. The red disc is a separate gas cloud. The fingers are thought to have been created as energy passed from the pulsar to the gas cloud. More>>
