A dying star called a Supernova exploded 4.5 billion years ago. It triggered dust particles to join together to form a cloud. Because more and more dust particles were sucked into the cloud, it eventually caused the cloud to collapse in on itself. The cloud of dust started to spin and caused the temperature to rise. The temperature was so hot that there was enough energy to create nuclear reactions. The hydrogen atoms were fusing, and the atoms of hydrogen created helium. The explosion was “releasing enormous amounts of energy in the bursts.” This how the Solar System was created 4.5 billion years ago.
