Submission + - Chandra sees an oxygen factory in a nearby galaxy (harvard.edu)
NewYorkCountryLawyer writes: A fantastic image captured by the Chandra X-ray Observatory in Cambridge, Mass, shows the debris of a massive star explosion in the Large Magellanic Cloud, a small galaxy about 160,000 light years from Earth. The supernova remnant N132D is the brightest in the Magellanic clouds, and belongs to a rare class of oxygen-rich remnants. Most of the oxygen that we breathe on Earth is thought to have come from explosions similar to this one.
