The life cycle of a star has several important stages:
Nebula: This is a huge cloud of gas and dust. It’s where stars begin their journey.
Protostar: As gravity pulls materials together, a protostar forms. The temperature inside gets really hot, around 10,000 degrees Kelvin!
Main Sequence: This is the longest stage, lasting about 90% of a star's life. During this time, hydrogen changes into helium. The temperature reaches about 10 million degrees Kelvin.
Red Giant/Supergiant: When a star uses up all its hydrogen, it becomes a red giant or supergiant. This means it can grow to more than 100 times the size of the Sun!
Supernova or Planetary Nebula: For very large stars, they end their lives in a powerful explosion called a supernova. For medium-sized stars, they create a beautiful planetary nebula and leave behind a white dwarf.
Black Hole or Neutron Star: What happens next depends on how big the star was. After a supernova, the remains can turn into either a black hole or a neutron star, which are very dense objects.
These stages show how stars change and evolve throughout their lives!
