Sagan became associated with the catchphrase “billions and billions” after being impersonated by Johnny Carson onThe Tonight Show (shown below). Sagan claimed the only time he ever used the phrase was in a passage in the book Cosmos. This inspired the creation of the sagan unit of measurement, which is defined as a number equal to at least four billion.

“A galaxy is composed of gas and dust and stars--billions upon billions of stars.”
