The search for extraterrestrial intelligence is getting a signal boost

It's all thanks to renewed interest from NASA and a private effort to scan the skies using an array of 64 radio telescopes.

Is There Anybody out There?

The Planetary Society has supported SETI, the search for extraterrestrial intelligence, practically since our founding in 1980. Learn the past, present, and future of SETI.

Doing SETI Better by Understanding Ourselves

One of the reasons SETI is hard is that we don’t know exactly what we are looking for, and part of that difficulty is that we still aren’t sure of who we are. An astronomer and an anthropologist team up to explore how cultural myopia shape what we can find in the cosmos.

Let’s be careful about this “SETI” signal

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

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.

Cosmos with Cosmos Episode 12: Encyclopedia Galactica

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.

Planetary Radio: Looking for Intelligence in a Flash

An update on the Planetary Society's improved Optical SETI search, with Harvard's Paul Horowitz and Curtis Mead.

Our Improved Optical Search for ET

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.

Optical SETI Gets a Major Upgrade

The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics.

One Man's Quest for SETI's Most Promising Signal

A review of Robert H. Gray's

[email protected] Following Up on Kepler Discoveries

Remember [email protected]? The ground-breaking computing project is now taking a look at candidate Earth-like planets that have been detected by NASA's Kepler space telescope.

Citizen Science projects for Planetary Science: Get Involved! Do Science!

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.

Arsenic and Deep Space?

If you or I ingest arsenic, well...it doesn't go so well. If you are, on the other hand, a certain species of bacterium from Mono Lake, California, ingesting this seemingly toxic metal is simple enough.

Update from the [email protected] Workshop

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.

More from the [email protected] Workshop

Today's sessions at the [email protected] conference stretched the mind as these multidisciplinary gatherings usually do.

Report from SETI workshop marking 50 years since Project Ozma

Jon Lomberg repots from NRAO--the National Radio Astronomy Observatory-- in Greenbank, West Virginia on a SETI workshop marking the 50th anniversary of Project Ozma.

New Pulsar Discovery Shows Power of Citizen Scientists and Planetary Society Members

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 [email protected], a descendant of the [email protected] project.

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.

Astropulse: A Fresh Look at the Skies in Search of E.T.

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

SERENDIP Takes a Great Leap Forward

Just when [email protected] is celebrating its 10th anniversary, its older brother, Project SERENDIP, is getting a general makeover.
