Editor’s note: In case you have not spent time going through the torrent of images from the two NASA Astrobiology Mars Rovers currently in operation, there’s one feature on Mars […]
In a paper published in the Astronomical Journal, a team of researchers from the SETI Institute, Berkeley SETI Research Center and the University of Washington reported an exciting development for […]
Scientists and engineers at the CU Boulder will soon take part in an effort to collect a bit of stardust—the tiny bits of matter that flow through the Milky Way […]
In a groundbreaking cosmic quest, the SETI Institute’s Commensal Open-Source Multimode Interferometer Cluster (COSMIC) at the Karl G. Jansky Very Large Array (VLA) is expanding the search for extraterrestrial intelligence […]
Our first confirmed proof of life beyond Earth might not involve biology at all. It’s possible that we might intercept communication through electromagnetic waves, like radio, or find telescopic evidence […]
The ‘Fermi paradox’ refers to the mismatch between a widely held expectation that advanced technological life should be common in the Universe—recently given impetus by the discovery that other planetary […]
![Planets capable of supporting high O2 concentrations and, hence, technological civilizations. This figure shows the likely composition of planetary atmospheres based on mass and equilibrium temperature. For planets whose temperature and mass would lead to primarily CO2/N2/H2O atmospheres, high oxygen levels require a biological origin, i.e. photosynthesis. For higher equilibrium temperatures, high O2 levels can occur via the runaway greenhouse effect and the photolysis of water vapor at high altitudes.

In the quest to understand the potential for life beyond Earth, researchers are widening their search to encompass not only biological markers, but also technological ones.
Since the commencement of the first SETI observation in 2019, China’s Search for Extraterrestrial Intelligence program has garnered momentum through domestic support and international collaborations. Several observations targeting exoplanets and […]
Abstract — Attendees at the First Penn State SETI Symposium collaborated to develop guideposts for monitoring for and communicating with extraterrestrial life.
A team of scientists from the SETI Institute, University of California Davis and the Alaska Whale Foundation, had a close encounter with a non-human (aquatic) intelligence.
