Stories, updates, insights, and original analysis from The Planetary Society.
Arecibo helped us explore the cosmos and our solar system, search for life, and defend Earth from potentially dangerous asteroids.
If you're expecting to gather with extended family on Thanksgiving, avoid the politics. Here are some conversation starters to use at the dinner table that everyone can engage in.
It's all thanks to renewed interest from NASA and a private effort to scan the skies using an array of 64 radio telescopes.
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.
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.
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.
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 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.
An update on the Planetary Society's improved Optical SETI search, with Harvard's Paul Horowitz and Curtis Mead.
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.
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.
This week's Planetary Radio features artist Jon Lomberg inviting listeners to join the New Horizons Message Initiative.
The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics.
A review of Robert H. Gray's
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 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.
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.
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.
Today's sessions at the [email protected] conference stretched the mind as these multidisciplinary gatherings usually do.
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.
