Speculation about the existence of advanced forms of life in the Universe and in our galaxy, has been since ever a subject of fascination and discussion in fiction, as well […]

A Firefly-inspired Model For Deciphering The Alien
The Search for Extraterrestrial Intelligence (ETI) is, historically, a search for aliens like us, inspired by human centric ideas of intelligence and technology.
A Reassessment Of The “hard-steps” Model For The Evolution Of Intelligent Life
According to the “hard-steps” model, the origin of humanity required “successful passage through a number of intermediate steps” (so-called “hard steps”) that were intrinsically improbable in the time available for […]
Wind Power As A Technosignature On M-dwarf Planets
We suggest that the large-scale deployment of wind turbines on an M-dwarf planet could produce observable technosignatures.
Artificial Broadcasts as Galactic Populations: III. Constraints on Radio Broadcasts from the Cosmic Population of Inhabited Galaxies
Any population of artificial radio broadcasts in a galaxy contributes to its integrated radio luminosity.
Artificial Broadcasts as Galactic Populations: II. Comparing Individualist and Collective Bounds on Broadcast Populations in Single Galaxies
The search for extraterrestrial intelligence includes efforts to constrain populations of artificial broadcasts in other galaxies.
Artificial Broadcasts as Galactic Populations: I. A Point Process Formalism for Extraterrestrial Intelligences and Their Broadcasts
Artificial broadcasts from extraterrestrial intelligences (ETIs) are a hypothetical class of celestial phenomena.
How Technological Acceleration Shrinks SETI’s Narrow Detection Window
The search for extraterrestrial intelligence (SETI) has historically focused on detecting electromagnetic technosignatures, implicitly assuming that alien civilisations are biological and technologically analogous to ourselves.
How Common Are Biological ETIs in the Galaxy?
The closest technological species to us in the Milky Way galaxy could be 33,000 light years away and their civilisation would have to be at least 280,000 years, and possibly […]
A Deep SETI Search For Technosignatures In The TRAPPIST-1 System With FAST
The Five-hundred-meter Aperture Spherical Telescope (FAST) is the world’s largest single-dish radio telescope, and the search for extraterrestrial intelligence (SETI) is one of its five key science objectives.
