Transcription: A star like our sun is born from clouds of hot gas and dust left behind when another star dies. As the cloud cools, it collapses into a spinning disk of particles bound by gravity. The particles in the center of the disk are packed so tightly together that friction causes them to heat up and glow. A protostar is formed. As the protostar gathers more mass, the atoms in its center fuse together in a nuclear reactor. A powerful blast of energy is released, igniting the nuclear furnace that will power the star throughout its life. A medium-sized star like our Sun has enough hydrogen fuel to live f ...
