这只“上帝之手”是由超新星爆炸引起的。爆炸后该星迅速形成一颗12英里宽的脉冲星，该脉冲星深隐于手腕上的白团里。
It looks like a hand of God reaching out into the cosmos, but NASA says the display is caused by a young and powerful pulsar.
Taken by NASA's Chandra X-ray observatory from it's orbiting 360 miles above the Earth, the recently released photo of Pulsar B1509 captures the X-Ray nebula in a state shaped like a human hand.
"The finger-like structures are apparently caused by energizing knots of material in a neighboring gas cloud," NASA said.
NASA estimates the shape spans 150 light years, but it is caused by a dense neutron star that's just 12 miles in diameter.
Astronomers believe B1509 is roughly 1,700 years old and is located 17,000 light years from Earth.作者: liuqunb 时间: 2009-4-17 22:46
