Unexpected Nebula Picture from Outer Space
Perfectly timed for Halloween, NASA is showing off a remarkable image of a ‘ghost nebula’ captured by the Hubble Space Telescope.
“The Ghost of Cassiopeia” is located 550 light-years away in the constellation Cassiopeia the Queen, NASA explains in a statement. The constellation is named after the vain Cassiopeia from Greek mythology and its ‘W’ shape is said to resemble the queen on her throne.
A light year, which measures distance in space, equals 6 trillion miles.
