When pondering the number of extraterrestrial civilizations, it is worth noting that even after it got started, the success of life on Earth was not a foregone conclusion. We recount some thrilling episodes from the history of our planet, some well-documented but others merely theorized: our collision with the planet Theia, the oxygen catastrophe, the snowball Earth events, the Permian-Triassic mass extinction event, the asteroid that hit Chicxulub, and more, including the global warming episode we are causing now. All of these hold lessons for what may happen on other planets.
When & Where
The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.
We believe we are conducting the most profound search in human history — to know our beginnings and our place among the stars.
The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach.
Every week the SETI Institute hosts a lecture series that is open to the public, provides free PB&J's and gives people a unique opportunity to interact with some of the world's leading space scientists.
