Outer Space

25 Outer Space What would you hear if you were in outer space and a star exploded? Well, you would not hear a thing. What? That is right. You can't hear any sound in outer space. What would you feel if you were walking in outer space? You would feel very cold. Outer space is about 270C below zero. That's really, really cold!
