We model the settlement of the galaxy by space-faring civilizations in order to address issues related to the Fermi Paradox.

The detection of laser radiation originating from space is a positive indicator of Extra Terrestrial Intelligence (ETI).

We apply classical machine vision and machine deep learning methods to prototype signal classifiers for the search for extraterrestrial intelligence. Our novel approach uses two-dimensional spectrograms of measured and simulated radio signals bearing the imprint of a technological origin.

The Search for Extraterrestrial Intelligence (SETI) makes certain assumptions which guide all current search programs. To illustrate some, this includes (1) that interstellar flight is not possible (2) that the motivations of interstellar cultures are based largely on anthropomorphic understandings of homo sapiens (3) that the Fermi Paradox and the Drake equation are the starting point (axioms) of all reasoning

The Search for Extra-terrestrial Intelligence (SETI) aims to find technological signals of extra-solar origin. Radio frequency SETI is characterized by large unlabeled datasets and complex interference environment.

For the first time ever, scientists have developed a way for the SETI community to keep track of, and update, all SETI searches that have been conducted and the results.

We report on high-resolution spectra obtained by the Automated Planet Finder and high resolution optical Levy Spectrometer and the search for periodic spectral modulations, such as those reported in Borra (2016).

It's the first time a visitor from another star system has been seen nearby. But what is it? An asteroid, a comet ... or an alien artifact?

In 1974, the Arecibo Observatory made history by beaming the most powerful radio message into deep space ever made.

If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light -- a beacon strong enough to attract attention from as far as 20,000 light-years away.

Bayesian Approach to SETI

The search for technosignatures from hypothetical galactic civilizations is going through a new phase of intense activity. For the first time, a significant fraction of the vast search space is expected to be sampled in the foreseeable future, potentially bringing informative data about the abundance of detectable extraterrestrial civilizations, or the lack thereof.

A Stunning Short Video: "Scavenger"

In 1977 NASA launched two golden records into deep space on the Voyager I and II probes. Having left our solar system, they are the most distant human-made objects. The records carry sounds and images of our planet and human brainwaves.

We estimate the relative likelihood of success in the searches for primitive versus intelligent life on other planets.

Breakthrough Listen - the initiative to find signs of intelligent life in the universe - announced today that a survey of millions of stars located in the plane of our galaxy, using the CSIRO Parkes Radio Telescope ("Parkes") in New South Wales, Australia, has commenced.

A star enshrouded in a Dyson sphere with high covering fraction may manifest itself as an optically subluminous object with a spectrophotometric distance estimate significantly in excess of its parallax distance.

A well-known experiment with young people bouncing a ball showed that when an observer focuses on counting the passes, he does not detect if someone crosses the stage disguised as a gorilla.

A telescope in outback Western Australia has been used to listen to a mysterious cigar-shaped object that entered our Solar System late last year.

It has recently been argued from a laser engineering point of view that there are only a few magic colors for optical SETI. These are primarily the Nd:YAG line at 1064 nm and its second harmonic 532.1 nm.

We describe a new approach and algorithm for the detection of artificial signals and their classification in the search for extraterrestrial intelligence (SETI).

Analysis of Kepler mission data suggests that the Milky Way includes billions of Earth-like planets in the habitable zone of their host star.
