Veil Nebula Supernova Remnant

From NASA:

This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun. The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.

One man’s perspective on the ecological and historical significance of the Tibetan landscape, as seen from space. Also of interest is the the source of this article’s photography, the Gateway to Astronaut Photography of Earth, even though its database is so vast it’s tough to navigate.


The Astronomy Picture of the Day is a NASA-affiliated website that posts recent deep-space photography for public consumption. They have a 2015 calendar available as a free PDF download that is absolutely spellbinding. Get it here, and while you’re at it, enjoy their photo of the day for October 30th: A Spectre in the Eastern Veil

Explanation: Frightening forms and scary faces are a mark of the Halloween season. They also haunt this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky in the constellation Cygnus, this portion of the eastern Veil spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil’s estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through broad and narrow band filters, emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen atoms in blue-green hues. Of course, in the western part of the Veil lies another seasonal apparition, the Witch’s Broom.
