Optical SETI's Growing Capabilities

Often, the phrase “next steps” has been known to describe things that don't actually happen. But for The Planetary Society's All-sky Optical SETI, it's different. Here's what's happened in the last year.

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

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

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.

The Planetary Society Optical SETI Telescope Opens

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.

Analyzing Signals in Real Time

Candidate signals sent in by users around the world will be quickly analyzed and compared to existing signals.
