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?

On April 11, 2006, a new era dawned in the search for extraterrestrial intelligence (SETI) with the dedication and beginning of operations of The Planetary Society Optical SETI Telescope in Harvard, Massachusetts. It is the first devoted optical SETI telescope in the world. The telescope was constructed by Paul Horowitz and his group at Harvard University using funding from Planetary Society members.

As SETI@home has demonstrated, untold millions around the world are ready and eager to donate their computer time for the advancement of knowledge and the benefit of humankind. The story of distributed computing is only just beginning.

BOINC stands for the “Berkeley Online Infrastructure for Network Computing.” Its purpose is to spread the credo of distributed computing beyond SETI@home, by making it easy for researchers in all fields to launch their own projects, and tap into the enormous computing capacity of personal computers around the world.

Faster and more regular sky surveys, at an increased sensitivity and broader bandwidth, will push the boundaries of SETI to new and unexplored territories.

It has been more than a year since the SETI@home crew spent a hectic week at Arecibo, pointing the giant radio telescope at some of SETI's most promising targets. Much of the data collected during the reobservations has since been repackaged as work units, and sent out to users around the world for analysis.

SETI@home and BOINC are gradually converging, and the benefits for both are substantial. While SETI@home enjoys the increased flexibility of the BOINC platform, it brings to BOINC something of inestimable value to a distributed computing project: millions of SETI@home users, willing to use their computers' processing power for the advancement of scientific research.

SETI@home chief scientist Dan Werthimer and his team went back to Arecibo to reobserve the most promising candidate signals detected by the project so far. Unlike most of the year, when SETI@home piggy-backs on the regular operations of the telescope, this time the Werthimer's crew had the full use of the resources of the giant dish.

SETI@home's Stellar Countdown has come to an end at the Arecibo Radio Observatory. All in all the Stellar countdown observed 227 promising locations in the sky. Within the next few weeks all the data collected and recorded will be processed by SETI@home users around to world.

After getting bumped off the telescope last week to make way for Solar flare observations, SETI@home Chief Scientist Dan Werthimer and his crew will spend 14 hours today observing the locations of SETI@home's most promising candidate signals, as well as a few other interesting locations.
