Planetary Society's Optical SETI Telescope Offers Online View of Night sky

Posted by Bruce Betts on 2007/10/30 12:00 CDT

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.

Telescope shows its Amazing Capabilities

Posted by Bruce Betts on 2006/07/11 12:00 CDT

During a few observation sessions in late April, the new Optical SETI Telescope was already demonstrating its amazing capabilities. Over three nights, the telescope completed 17 hours of observation, under the direction of Paul Horowitz and his team of Harvard graduate students. During that time, the telescope observed 1% of the sky, looking for the briefest flashes of light coming from outer space.
