debris of the star. Destruction and creation were conjoined on the screen. The elements revealed there, like those from countless earlier supernovas, will eventually find their way into new stars and perhaps new planets, Gal-Yam said. He added: "I'm just really happy to be observing this." The star had begun its race to destruction long before that night on Palomar, when it began to lose a lifelong fight against gravity. Gravity is responsible for setting newborn stars aflame, by squeezing atoms of hydrogen in the star's core so tightly that they fuse to make helium. The fusion generates light and heat and also exerts pressure that allows the core to withstand the enormous weight of the star's outer layers. But when the core consumes all of its hydrogen, gravity compresses it. The temperature of the shrinking core rises to about a hundred million degrees, hot enough for helium nuclei to fuse and make carbon
