Using new technologies, NASA and European Space Agency scientists have released a stunning updated image of the Veil Nebula, the beautiful remnants of a supernova that occurred 10,000 years ago.
The remnants of the supernova, called the Cygnus Loop, were the result of the death of a star 20 times the mass of the sun that exploded about 2,100 light-years away.
The star’s hollow remnants span 110 light-years, after being formed by an exceptionally strong stellar wind that blew before the star transformed into a supernova.
The wind dispersed the primary gas emissions from the star before the resulting explosion shone like neon veins running along the cavity walls of giant filaments of “stellar debris”.
Hubble Space Telescope operators released the stunning image in 2015, which was captured with the Wide Field Camera 3 tool.
More recently, scientists have reprocessed the original data with new techniques to produce a more exciting image that displays the celestial interpretation of “out loud.”
The image shows how the technically accurate processing of data has come from distant human probes, providing new insights into the interstellar processes that create the vast structures across the universe.
The picture shows different gases in various colors: blue for ionized oxygen twice, red for ionized hydrogen and ionized nitrogen.
The green gases were not affected by the supernova shock wave and thus appear to be more diffuse as they were allowed to settle.
Comparing 2015 Hubble images with previous images of the nebula from 1997, scientists have suggested that it is expanding at a rate of 1.5 million kilometers (932,000 miles) per hour, or 117 times the diameter of the Earth.
Ultimately, the remnants of the hot young star who died in this dramatic way will be disposed of, and his gaseous remains will be dispersed in the interstellar medium.
