What the astronauts saw was a dynamic world of swirling clouds, multiple hues of blue water, and smaller patches of brown. Our planet, reduced by distance, became for the astronauts an oasis of beauty against the stark bareness of the moon's dead surface. Whether I think it would be inhabited or not. We'll probably never know what a lonely traveler from another planet will think about Earth. The image gave us our world for the first time in a much great context - of the solar system and of the universe itself.
Earth is beautiful.
It is alone. It is unique. It is fragile. It is our home in space, our protector, our life. The vast loneliness up her is awe-inspiring, and it makes you realize just what you have back there on Earth.
