May 14th, 2008 1pm EST: "Scientists today reported the discovery of the youngest supernova in the Milky Way, ending a 50-year search for the exploded stars that remain mysteriously difficult to spot in our galaxy. The supernova, given the obscure name of G1.9+0.3, was detected via remnants from the powerful, element-rich blast it set off an estimated 140 years ago. The youngest previously known supernova, called Cassiopeia A, was 330 years old. Astronomers have scoured the skies for supernovae since Cassiopeia surfaced in the 1950s. Only a half-dozen of the stellar explosions have been noted in the last millennium, but somewhere between 20 and 30 should be occurring in the Milky Way based on galactic evidence. "It's clear that we've not been getting our share [of supernovae] ... this lack is a significant puzzle," North Carolina state university scientist Stephen Reynolds, who aided in the search, said. The supernova shortage becomes particularly significant given the vital role played by remnants, which are the burning trails of hot gas that depleted stars give off for hundreds of years after an initial explosion. Supernova remnants circulate necessary elements such as radium and cobalt throughout the universe. Scientists estimate that most of the earth's heavier elements were deposited on the planet in its early life via remnants. "They drive the lives of our galaxy," Reynolds said. Robert Kirshner, an astrophysicist at Harvard university's Smithsonian centre, put it poetically: "We're all stardust ... this is a stellar death and the corpse is still warm." The young supernova was discovered by using telescopic images taken in 1985 and last year by the US national aeronautics and space administration to measure the age of the exploded star. While the supernova registered on this planet sometime in the 1860s, it had to travel thousands of light years to reach Earth, meaning that the actual star in question flamed out several millennia ago."
Do you believe it?
I have seen many pictures of Supernovas, this one is vastly different looking when compared to the other known Supernovae in our Galaxy!
