NASA has released an image of a supernova remnant (SNR) called 'Puppis A,' which contains dust and gas cloud in the form of a 'glowing red rose'. The image was captured by NASA's WISE (Wide-field Infrared Survey Explorer).
SNR refers to the floating particles of dust and gas cloud that result from the explosion of a star, called supernova. In the case of Puppis A, the star had exploded about 3,700 years ago and the expanding shock waves from that explosion are heating up the surrounding dust and gas clouds, causing them to glow and creating the beautiful red cloud of 'rose.'
Inside this supernova, there is also a 'neutron star,' an incredibly dense object formed by some of the materials flung into space by the violent explosion. This neutron star is traveling at a whopping 3 million miles per hour speed and, astronomers, astonished and perplexed by its inexplicable speed, have nicknamed it the 'Cosmic Cannonball.'
In NASA's image, green-colored gas and dust surrounding Puppis A can also be seen. The green gas and dust are actually the remnants of another supernova - the Vela - and was formed when a star exploded 12,000 years ago.
Vela SNR is four times closer to the Earth than Puppis A and, together, these remnants would be among the largest and brightest objects one would see in the sky, if you had X-ray vision like the comic book hero Superman, NASA said.
