X-ray & Optical Images of SNR E0519-69.0 – 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.

8 billion years later, 4.6 billion years ago, our Grandmother Star becomes a supernova.She gives up her life in an explosion of possibilities . She becomes a supernova giving rise to our Star, what we call the Sun. The Grandmother Star was huge in comparison to her child and when she exploded she formed a ball nearly 5 million times the diameter of the Sun. Our sun in mainly composed of hydrogen (which composes about 90% of all the atoms in the universe).
