George's Cosmic Treasure Hunt

"We are going," said Annie, "on a great cosmic journey. So listen up, Savers of Planet Earth, and prepare to meet the Universe."

George's best friend Annie needs help. Her scientist father, Eric, is working on a space project - and it's all going wrong. A robot has landed on Mars, but is behaving very oddly. And now Annie has discovered something wierd on her dad's super-computer.

Is it a message from an alien?

Could there be life out there?

How do you find a planet in outer space?

And if you could talk to aliens, what would you say?
