You are here, in the middle of the universe on a blue dot.
The author and astronomer, Carl Sagan said this of the scientists who study this planet:
“It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light, that transparent air reflects light, that in so doing it discriminates among the waves, and that the sky is blue for the same reason that the sunset is red?
It does no harm to the romance of the sunset to know a little bit about it.”
The excerpt from Carl Sagan’s speech which follows was inspired by an image taken, at Carl Sagan’s suggestion, by Voyager 1 on February 14, 1990 as the spacecraft left our planetary neighborhood for the fringes of the solar system, engineers turned it around for one last look at its home about 6.4 billion miles away.
