Caption: G292.0+1.8 is a young supernova remnant located in our galaxy. This deep Chandra image shows a spectacularly detailed, rapidly expanding shell of gas that is 36 light years across and contains large amounts of oxygen, neon, magnesium, silicon and sulfur. Astronomers believe that this supernova remnant, one of only three in the Milky Way known to be rich in oxygen, was formed by the collapse and explosion of a massive star. Supernovas are of great interest because they are a primary source of the heavy elements believed to be necessary to form planets and life.
