Extraterrestrials is a hypothetical concept that supposes that higher intelligences exist on other planets in other solar systems. At the behest of the Pentagon, astrophysicist Frank D. Drake headed Project OZMA, in 1960, to determine a number of "active, communicative extraterrestrial civilizations in the Milky Way galaxy."
Project OZMA[edit | edit source]
In 1961, a SETI conference was held at the Green Bank Observatory, which is located in the United States National Radio Quiet Zone in Green Bank, West Virginia, to debrief attendees on Project OZMA's agenda and to discuss what later became known as the "Drake Equation".
There were ten attendees at the conference who were dubbed "The Order of the Dolphin", organizer J. Peter Pearman, Frank Drake, Philip Morrison, businessman and radio amateur Dana Atchley, chemist Melvin Calvin, astronomer Su-Shu Huang, neuroscientist John C. Lilly, inventor Barney Oliver, astronomer Carl Sagan and radio-astronomer Otto Struve.
