Radio SETI experiments aim to test the hypothesis that extraterrestrial civilizations emit detectable signals from communication, propulsion, or other technologies.

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.

Since the beginning of civilization, humanity has wondered whether we are alone in the universe. As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address this fundamental question.

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.
