Stories, updates, insights, and original analysis from The Planetary Society.
Technologies for studying planets around other stars are advancing all the time. Along with those advancements come new ways to look for possible signs of life on those planets.
SETI is the search for extraterrestrial intelligence, using various techniques to look for signals from advanced alien civilizations. METI (messaging extraterrestrial intelligence) is when we send out our own signals for aliens to find.
Discover what causes a comet’s color and what it might be like to listen to one whiz by.
Exoplanets with terminator zones are unusual worlds that may challenge our traditional understanding of habitability.
Is there life on Venus? Was our planetary neighbor ever inhabited? Here are the answers to your most pressing questions about the possibility of alien life on Venus.
The real science of aliens, the policy implications of ET, and new views of worlds beyond our own.
An exploration of whether aliens are out there, what kind of extraterrestrial life is most likely to exist, and how we're looking for it.
New discoveries from Ryugu, material heading our way from Bennu, and anticipation for a mission to Psyche.
When searching for extraterrestrial life, we have to base our hunt on what we know about life on our own planet. This may seem limiting, but there's a lot we can learn from the astonishingly diverse lifeforms we have here on Earth.
When we combine data sources, collaborate with each other, and invite artistic perspectives, we can better understand the Universe we live in.
Will a SETI signal unite or divide us?
NASA's JWST recently detected carbon dioxide in the atmosphere of an exoplanet known as WASP-39b — a historical first.
A look at the potential for habitable planets in binary systems despite their chaotic births.
Contact remains a unique movie due to its representation of science. It remains a great film due to the treatment of doubt and faith as a universal aspect of human existence.
We spoke with the scientists leading the first observations of TRAPPIST-1 using the James Webb Space Telescope (JWST) in order to understand what mysteries their observations will help unlock.
From gas orbiting a supermassive black hole to asteroids orbiting near the Earth, sometimes the vastness of space can feel a bit tight.
While NASA will launch Dragonfly later this decade to Titan, another potentially habitable moon of Saturn, no space agency is currently funding a mission to Enceladus.
Explore the two-faced Moon and meet two new projects paving the way for the future of space science.
The new STEP Grants program is designed to regularly compete a significant portion of The Planetary Society’s science and technology portfolio.
Ocean worlds are among the best candidates to search for life.
