Did you know that stars, like humans, also go through a life cycle? Stars are born from clouds of gas and dust called nebulae. These clouds of interstellar material begin to collapse under their own gravity, forming a protostar. As the protostar grows in mass and temperature, nuclear fusion begins in its core. This marks the birth of a star, where hydrogen atoms are fused into helium, releasing an immense amount of energy in the form of light and heat. The star enters its main-sequence phase, where it will spend the majority of its lifetime. When a star exhausts its hydrogen fuel, it begins to change. Small stars like our sun will expand into Red Giants, while larger stars will undergo a supernova explosion. The core of a massive star may collapse into a neutron star or black hole. The remnants left behind by a dying star can contribute to the formation of new stars and planets, continuing the cycle of star formation in the universe. Understanding the life cycle of stars is crucial in helping us learn more about the cosmos and our place in it.
