Sir JAMES JEANS, F.R.S. : ' Our window into space-the Sky '
Continuing our journey with Sir James Jeans through time and 'pace, we are now in imagination to charter a rocket and go on a tour of the moon. Soon after leaving the earth's surface we shall notice the sky becoming black and the sun blueish, and these conditions will persist even after we have landed on the moon, because it has no atmosphere.
