Carl Sagan on Extraterrestrials

The incomprehensible vastness of the universe, the wonder of our own place in it all… Carl Sagan was able to explain the science of space in a way everyone could understand.

Among his long list of roles and accomplishments, the Cornell professor and NASA advisor is possibly best known for the 13-part television series, Cosmos, which reached millions of people worldwide and sealed his place as celebrity scientist. Maybe he was teased a bit for his tendency to say “billions”, a lot.

But Carl Sagan had this amazing talent for explaining the scientific wonders of the universe without losing the wonder. When he spoke about the science of space, he captured imaginations and held people in thrall. (Source: PBS’ Blank on Blank)
