Stars are massive, luminous spheres of plasma held together by their own gravity and are the fundamental building blocks of galaxies. The life of a star begins in the dense regions of nebulae, where gas and dust collapse under gravity to form a protostar, which evolves into a true star once nuclear fusion ignites in its core. This fusion process, primarily converting hydrogen into helium, releases enormous amounts of energy, which is the source of a star’s light and heat. Stars vary widely in size, mass, temperature, and color, influencing their life span and fate. Smaller stars like red dwarfs burn their fuel slowly and can shine for billions of years, while massive stars exhaust their energy rapidly and may live only a few million years before exploding in spectacular supernovae. The remnants of these explosions can lead to the formation of neutron stars or black holes. Throughout their life cycle, stars play a critical role in the synthesis and distribution of heavy elements, which are essential for forming planets and life as we know it. Understanding stars and their evolution is crucial for comprehending the universe’s history and future.
