Living on Earth, it is difficult to understand the size of our atmosphere. When we study other planets and Earth from space, we can understand the true thickness of our atmosphere.
Let us try an experiment. If the Earth were a sphere 1 foot in diameter, how thick would our atmosphere be? Start with your hand 2 feet above a table. Lower it slowly until to think you are at the top of the atmosphere … So where did you stop? A foot up? An inch up? The answer is about 1/4 inch.
Little atmosphere is between space and us. It is what protects us from gamma rays, x-rays and ultraviolet radiation. We could not to live here without atmosphere. It is all that we have and we cannot make more. It might be worth taking care of.
Come join us at the Insperity Observatory (humbleisd.net/observatory) for Public Night on the first Friday each month from sunset to 10 p.m.
