How Do We Know the Universe is Expanding?

Have you ever asked yourself: How Do We Know the Universe is Expanding? Like a giant balloon, everything is moving further apart.

Space is full of incredible mysteries and wild science! When we look up at the night sky, we are seeing things that are millions of miles away. Exploring the universe helps us understand how our own planet Earth was made.

But how do we study space? We use amazing machines! Engineers design powerful telescopes, giant rockets, and smart robots (like the Mars Rovers) to explore places humans can’t easily go. The math and science used to build these space machines is super important.

Do you want to build robots that could one day explore another planet? Programs like FIRST® Robotics (especially FIRST LEGO League for elementary students) teach you the exact same problem-solving skills that real rocket scientists use to explore the universe!
