Scientists have, for the first time, examined a detailed “time lapse” X-ray image of the expansion of a classical nova explosion using the GK Persei nova — a binary star system which underwent a nova explosion in 1901. Through this work, they hope to gain a better understanding of the expansion of gases in the universe, including not only in classical novae but also in supernovae — tremendous stellar explosions that are believed to be responsible for the creation of heavy elements such as uranium which cannot be produced by normal stars.
