Exploding star left a rose


15/12/2011

Around 3,700 years ago, people on Earth could see a new star in the sky. She slowly faded and was soon forgotten, until modern astronomers found its remains, which were called Puppis A. In this new image made by NASA’s Space Telescope Wide-field Infrared Survey Explorer (WISE), Puppis A is quite different from the rest of the supernova explosion, and the like, rather, a red rose.

Puppis A (sounds like a PAP-IPRS) was formed when a massive star ended its existence and become a supernova in the most powerful type of explosion in the known universe. Diverging shock waves from the blast heated dust and gas clouds around the supernova, causing them to glow red in the infrared spectrum. Although most of the matter of the original star was made in the space, some of it was left in an extremely dense object called a neutron star. Speaking specifically about the neutron star (too faint to be seen in this photo), then it moves incredibly fast: over 3 million miles per hour! Astronomers stunned similar rate, gave her the nickname "Cosmic Cannonball."

For a number of green gas and dust in this image are the remnants of an ancient supernova Vela. The explosion happened about 12,000 years ago, at a distance of four times closer than Puppis A. The colors in this image represent different wavelengths of infrared light that the human eye can not see.
