'Witch Head' Brews Baby Stars
A
witch appears to be screaming out into space in this new image from
NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared
portrait shows the Witch Head nebula, named after its resemblance to the
profile of a wicked witch. Astronomers say the billowy clouds of the
nebula, where baby stars are brewing, are being lit up by massive stars.
Dust in the cloud is being hit with starlight, causing it to glow with
infrared light, which was picked up by WISE's detectors.
The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.
WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned.

女巫頭星雲的估計是幾百光年遠的獵戶星座，只是關閉了著名的獵人的膝蓋。
智最近被“驚醒”追捕小行星名為NEOWISE程序。激活來到飛船後進入休眠狀態，按計劃在2011年，當它完成了兩個完整的天空掃描，。
