A fully formed planetary system, with five different planets of varying sizes and orbits has been found, orbiting a star more than 40 light years away. Significantly, it is the very same star, 55 Cancri, that was one of the chief targets of the [email protected] reobservations at Arecibo in March 2003.
The Planetary Society's Optical SETI Telescope was built solely to search for possible light signals from alien civilizations. Located at Oak Ridge Observatory in Harvard, Massachusetts, it is the first dedicated Optical SETI telescope in the world. Its 72-inch primary mirror also makes it larger than any optical telescope in the U.S. east of the Mississippi river.
Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.
Update as of March 4, 2007
Thanks to The Planetary Society Shoemaker Grant, the 1.06-meter KLENOT telescope optics was completed at the Klet Observatory. Regular observations of the KLENOT project started in March 2002 under the new IAU/MPC code 246, so we can now present results covering 5 years of this work.
Located in the southern part of the continent of South America, Southern SETI has a continuous view of densest star-fields in our galaxy. And, since 1990, it has been sponsored and supported by The Planetary Society.
Winter time is observing time at the Oak Ridge Observatory in Massachusetts, when humidity is low and the sky is often clear. And so it has been for the Optical SETI telescope, which opened its doors in April 2006.
