About This Chapter
How It Works:
- Identify the lessons in the ScienceFusion Life Cycle of Stars chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the star life cycle topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
Students will learn:
- Formation of stars
- Main sequence stars

1. Star Formation: Main Sequence, Dwarf & Giant Stars
Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.
2. How Lower-Main-Sequence Stars Die
Not every star lives or dies the same way. Red dwarfs and medium-sized stars have key differences that determine their lifespan and how they die. This lesson will tell you why that is the case.
3. Life Cycle of Neutron Stars
Discover the life of a neutron star, including how it's born after a supernova explosion and how its extreme pressure causes protons and electrons to combine into neutrons. Discover also how pulsars are rotating neutron stars that will eventually slow down to become regular neutron stars.
4. Supernova and Supergiant Star Life Cycle
Learn about one of the biggest explosions known to humankind - a supernova. Follow a star's life cycle and learn how a star changes from a red giant to a supernova to a black hole or neutron star.
5. Types of Star Clusters
Our lesson will explore what star clusters are, the two types of star clusters, and their characteristics and differences as well as how we can figure out their ages using the H-R diagram.
