How does a radio telescope work?

Scientists are building a giant radio telescope, one hundred times more powerful than the best in the world at the moment.

It's called the Square Kilometre Array (SKA) project and is one of the biggest scientific projects in history.

When the telescope is finished it'll see further into the cosmos than ever before, to help us discover new galaxies and maybe even find alien life.
