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.

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.
