| 30 October 2013 A Spectre in the Eastern Veil The Veil Nebula is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. Roughly circular in shape, covering nearly 3 degrees on the sky in the constellation Cygnus, only appears to be the size of the Moon. Emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen atoms in blue-green hues. This seasonal apparation is especially haunting in the spooky attitudes of the holiday tomorrow. One might even see veins in blue/red hues, or see distorted faces of ghastly figures, if feeling especially haunted. HAPPY HALLOWEEN! |
