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?
An update on the Planetary Society's improved Optical SETI search, with Harvard's Paul Horowitz and Curtis Mead.
In episode 2 we switch from cosmos to microcosm and discover how we are connected to all living things. Is Sagan too authoritative in this episode? Plus, a major error in one of the stories.

The Planetary Society Optical SETI (OSETI) Telescope was successfully upgraded and fully tested, and is now fully operational looking for aliens. Here are some updates on the performance and progress. In summary, the upgraded telescope is performing just as hoped and is scanning the skies.
The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics. The telescope, which has been operating the only all-sky optical SETI survey since its opening in 2006, is run by Harvard University Professor Paul Horowitz and his team. The telescope scans the sky every clear night with a 72-inch primary mirror, looking for laser pulses as short as one billionth of a second that could be transmitted by distant extraterrestrials. When observing, it has been able to process 1 terabit (trillion bits) of data every second, that’s as much as in all the books in print every second.
