Cosmos

by Carl Sagan

Overview

In 1997, there came a movie that would forever change the way we see outer space. The movie was about a woman researching messages from outer space in an effort to communicate with extraterrestrial life. After a lot of waiting, something finally comes through on their giant radio telescopes. The signal gives a blueprint for a machine that can allow humanity to teleport and meet aliens across space. The movie's name was Contact, and Carl Sagan wrote the book it was based on.

Carl Sagan was an astronomer, planetary scientist, and cosmologist. There probably wasn't very much he didn't know about space. Although Contact was science fiction, Cosmos came first and is entirely fact-based. It's filled with incredible information that will fill you with curiosity about outer space.

Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.
