Looking at the Universe from the Earth's surface is a bit like a scuba diver viewing our world from the bottom of a swimming pool. Don't get me wrong. I love our atmosphere. It gives us air to breath, keeps our body's fluids liquid, protects us from cosmic rays as well as space rocks, and performs many other functions which make life on our planet possible. That being said the blanket of air which surrounds us makes it difficult to view objects in the Universe.
