Space Science

Frontiers are areas that have not been fully explored. There are very few frontiers left on Earth. However, beyond Earth there is a frontier bigger than we can possibly imagine-space.

The study of the universe is called space science, or astronomy. Scientists observe space using different telescopes and develop theories to explain what they see.

In Space Science, learn how scientists observe space and discover the scientific principles which form the basis of their theories about the cosmos.
