Several readers have contacted me recently about reports that a group of international astronomers have detected a strong signal coming from a distant star that could be a sign of a high-technology civilization. Here’s my reaction: it’s interesting, but it’s definitely not the sign of an alien civilization—at least not yet.
Back on the Rails with OSETI
Planetary Society OSETI Going Strong

The Planetary Society sponsored all-sky optical SETI search at Harvard University went off the rails, telescope roof rails that is, but it is back on track and hunting the sky for ET.
Discover the Universe including the Big Bang, dark matter, dark energy, galaxies, life and more in this video of class 13 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
Cosmos with Cosmos Episode 12: Encyclopedia Galactica
In which we ponder the existence of others
Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.

The All-Sky OSETI Search Gets Even Better
An update on the Planetary Society's improved Optical SETI search, with Harvard's Paul Horowitz and Curtis Mead.
Cosmos with Cosmos Episode 2: One Voice in the Cosmic Fugue
In which we are connected to all living things
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.
Our Improved Optical Search for ET
New hardware processes terabytes of data every second

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.

Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.

Frank Drake used the 85' radio telescope at Green Bank to conduct the first modern Search for Extraterrestrial Intelligence in 1960. Using a very simple receiver and no computers, he listened to each of two sunlike stars for 100 seconds. Call that unit 1 Ozma.

Planetary Society members have reason to celebrate today, with the on-line publication in Science of the discovery of a new pulsar by three citizen-scientists working with Einstein@home, a descendant of the SETI@home project.

If you were a member of an alien civilization trying to communicate across the immeasurable distances of space, how would you go about it?
