New research by University of Texas at Dallas geoscientist Dr. Robert Stern and a colleague suggests a geological explanation for why conclusive evidence for advanced extraterrestrial (ET) civilizations has not […]
The SETI Ellipsoid is a strategy for technosignature candidate selection which assumes that extraterrestrial civilizations who have observed a galactic-scale event — such as supernova 1987A — may use it […]
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 […]
Abstract — Attendees at the First Penn State SETI Symposium collaborated to develop guideposts for monitoring for and communicating with extraterrestrial life.
Assuming civilizations have similar interplanetary communications and radar capability to NASA’s Deep Space Network, what is the feasibility of intercepting their communications?
Astrophysicists from Trinity College Dublin are scanning the Universe for “technosignatures” emanating from distant planets that would provide support for the existence of intelligent, alien life.
In a new study published in the Astronomical Journal, researchers used the known population of exoplanets and extrapolated to the much larger, unknown population of exoplanets to set better thresholds […]
The primary goal of the search for extraterrestrial intelligence (SETI) is to gain an understanding of the prevalence of technologically advanced beings (organic or inorganic) in the Galaxy.
Humanity has wondered whether we are alone for millennia. The discovery of life elsewhere in the Universe, particularly intelligent life, would have profound effects, comparable to those of recognizing that […]
