the gold you have in your bracelet, earring, or necklace? it was forged in the heart of a dying star much larger than our own, in a brilliant and enormous explosion that, for a moment, outshone the entire galaxy.
When a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way, it left behind an expanding shell of debris called SNR 0519-69.0. Here, multimillion degree gas is seen in X-rays from Chandra (blue). The outer edge of the explosion (red) and stars in the field of view are seen in visible light from Hubble.
