Life in the Universe
Could humans be the only intelligent beings in all the vastness of the universe? Or are we just one humble race, a member of a vast intergalactic fraternity of advanced civilizations? SETI, the Search for Extraterrestrial Intelligence, is the scientific quest to answer these great unknowns. As of now all we have are questions, but we know the answers, when they come, could transform our world. Since the day it was formed in 1980, The Planetary Society has been there to support the search.
And what about other life? Is there -- or was there ever -- anything else alive in our solar system? Did microbes once spring to life in oases on early Mars, or around the undersea volcanic vents of Europa or Enceladus? Could life have originated on Mars and been transported to Earth? We've never detected evidence for anything living elsewhere than our own fragile planet. Are we alone?

We are super excited that the Planetary Society’s Phobos LIFE (Living Interplanetary Flight Experiment) is about ready to launch to Mars’ moon Phobos and back. We have been working for years preparing this unique test of the effects of long term exposure to deep space on a wide variety of life.

In the middle of the night on June 1, 2011, millions of passengers returned safely to Earth as part of the great conclusion to space shuttle Endeavour's last flight, STS-134. Many of those millions of passengers were part of the Planetary Society's Shuttle LIFE experiment. Five different kinds of creatures from all three domains of life are part of Shuttle LIFE.

Frank Drake used the 85' radio telescope at Green Bank to conduct the first modern Search for Extraterrestrial Intelligence in 1960. Using a very simple receiver and no computers, he listened to each of two sunlike stars for 100 seconds. Call that unit 1 Ozma.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
