Veil Nebulae & Supernova Remnant

Veil Nebulae
Image description:

     NASA's Hubble Space Telescope imaged a  massive star that exploded nearly about 8,000 years ago. This star was named as Veil Nebulae, the debris is one of the best remnants which derived its name from delicate and draped filamentary structures. The entire nebulae is about 110 light years across, covering six full moons on the sky as seen from the Earth. It is located nearly about 2,100 light years away from the Constellation Cygnus, the Swan.

About Veil Nebulae:

     The Veil nebulae has mass which is equal to the 20 times the mass of our Sun. The fast moving blast wave shown in the picture is from the ancient explosion is plowing into a wall of cool, denser interstellar gas by emitting lights. It lies at the edge pf the low density gas that was blown into space by dying star prior to its self-detonation.

This image shows the collision of blast wave and the gas dust that makes up the cavity wall. The nebulae resembles a crumpled bed sheet viewed from the side.

Color Information of Veil Nebulae:

    The Red color denotes the glow of hydrogen, green corresponds to the Sulphur, and the blue from Oxygen. The Bluish features, outlining the cavity wall appears very smooth. The red filaments arise after gas is swept into shock wave at speeds of nearly 1 million miles per hour, so fast that it could travel from Earth to the moon in 15 minutes. Astronomers are comparing these new images to the im\ges taken by Hubble in 1997. This comparison allows scientists to study how the nebulae has expanded since it was photographs over 18 years ago.
