NASA : Veil Nebula Supernova Remnant .- Remanente de la supernova Velo Nebulosa

Hola amigos: A VUELO DE UN QUINDE EL BLOG, Llamada la nebulosa del velo, los escombros es uno de los remanentes de supernova más conocidos, derivando su nombre de sus delicadas estructuras filamentosas, drapeados. Toda la nebulosa se encuentra a 110 años luz de diámetro, cubriendo seis lunas llenas en el cielo visto desde la Tierra, y reside a unos 2.100 años luz de distancia en la constelación de Cygnus, y el Cisne.

NASA's Hubble Space Telescope has unveiled in stunning detail a
that exploded about 8,000 years ago.
Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan.
This view is a mosaic of six Hubble pictures of a small area roughly two light-years across, covering only a tiny fraction of the nebula’s vast structure.
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.
