It’s also Halloween in outer space! Look at this gigantic witch head screaming in the vastness of space about 900 light-years away from Earth.
Astronomers probably got shocked when they saw this weird structure for the first time! As you may have guessed, they called this greenish blue reflexion nebula spotted in the constellation Eridanus River the Witch Head Nebula (IC 2118). Yes, it resembles a scary witch face with an open wide mouth, which seems to expel a shrill scream.
The structure is a reflection nebula, which is brought to light by the brightest stars in Orion. The fog is greenish blue, because its fine dust particles reflect better blue than red. The pictures were taken by the NASA Space Telescope WISE.
Don’t be afraid, this weird space phenomenon, the Witch Head Nebula, is far, far away from us. It is located about 900 light-years away from Earth. And of course it does not appear only for Halloween.
Look at this mysterious cloud spotted from ISS.
