All stars have similar life stages until the star reaches the red-giant stage. As the gas in a nebula condenses, it forms a protostar. Eventually the temperature reaches roughly 15 million degrees and fusion starts. The star begins to glow brightly and contracts. It is now a star, which ...
Without stars, we would simply not exist. These cosmic behemoths use nuclear fusion to produce the elements that planetary systems and living beings are made of (carbon, oxygen, iron, etc.). The next sections will describe this process by outlining the different stages in the life cycles of...

Eventually, the core temperature of a star will reach the point that fusion its core can begin. This is the process that all stars go through as they convert protons of hydrogen, through several stages, into atoms of helium. This reaction is exothermic; it gives off more heat than it requ...
Learn about the life cycle of stars and what transpires over the billions of years they exist. Discover how they form in nebulae, and explore the three following stages known as the main sequence stage, the giant stage, and the cooling or explosive stage. ...
