Have you ever wondered what happens to the different stars in the night sky as they get older? This activity lets you explore the life-cycle of stars.
Star in a Box is an interactive webapp which animates stars with different starting masses as they change during their lives. Some stars live fast-paced, dramatic lives, others change very little for billions of years. The webapp visualises the changes in mass, size, brightness and temperature for all these different stages.
Are you a teacher? Do you want to use Star in a Box in your classroom lessons? These resources are designed to help you to explore the life-cycle of stars with your class.
If you would like to know more about how stars evolve, why not take a look at our SpaceBook pages about the life-cycle of stars.
