 Science in the stadium. A football pitch is made up of around one billion blades of grass. You would need at least 100 football pitches to match the number of stars in our galaxy. Astronomers think that most of these stars have planets. Are any of them like Earth? The simple truth is that we don't know. But astronomers are hunting for planets that are not too hot, not too cold, not too wet and not too dry, but just right. How would you search for life in the universe? Science is universal.
