Summary of Week 2

This week, you have travelled a long way! By taking a journey through the lifecycle of a star, you found out about red giants and white dwarfs, and what would happen to the Sun in five billion years’ time.

The tour ended with a bang, with stars exploding as supernova or collapsing into neutron stars, and material falling down a black hole.

In Week 3 you’ll start with a bang – travelling back in time, to learn about the Big Bang, in which space and time and all matter was created. You will also learn about different types of galaxies.
