Witch Head Nebula
October 31, 2013
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.
