- will we know it if we see it? To spot potential intelligent life out
there in the great beyond, first you must cast a net wide by using an array of
techniques and technologies. Any
"fishing expedition" for Extra - Terrestrials includes close-in
studies of life in extreme environments right here on Earth, to help us
recognize any signatures we might find on Mars or deep diving through the icy
shell of Jupiter's moon, Europa.

- CLOSE ENCOUNTERS
- will we know it if we see it?
-
- The search can use of space-based
telescopes to inspect Earth-like planets circling their home stars. Then
there's a proverbial ear to the cosmos using radio telescopes to pick up any
bustling interstellar civilization or perhaps look for far-off laser-pulsed
communiques from extraterrestrials.
-
- These and other efforts are actively pursued
by the SETI Institute in Mountain View, California. More than a hundred
institute scientists are busily carrying out research in astronomy and
astrophysics, astrobiology, as well as exoplanets, climate and bio-geoscience
and the Search for Extraterrestrial Intelligence (SETI).
-
- SETI work is still in the early stages.
However, more and more is taking place with an increasing number of instruments
and technologies around the world. For
example, there's the Commensal Open-Source Multimode Interferometer Cluster
Search for Extraterrestrial Intelligence, COSMIC SETI.
-
- All 27 antennas that constitute the Very
Large Array (VLA) in New Mexico have been outfitted with new gear to perform
24/7 SETI observations under a collaboration between the SETI Institute and the
National Radio Astronomy Observatory, the group that operates the VLA.
-
- SETI Institute's Allen Telescope Array,
situated northeast of San Francisco. Has
undergone high-tech upgrades. COSMIC is
the most comprehensive SETI search on a single instrument in history. COSMIC will analyze data for the possible
presence of "technosignatures" detectable signatures and signals that
shout out the presence of distant advanced civilizations.
-
- “Technosignatures” are viewed as a subset
of the far more established search for "biosignatures", evidence of
microbial or other primitive life loitering on some of the billions of
exoplanets we now know exist.
-
- The Allen Telescope Array (ATA) has
undergone antenna redesign and now is outfitted with high-end computers, signal
processors, and other electronics making it far faster than ever before.
-
- One output from ATA has been its use by
SETI Institute scientists to delve into powerful Fast Radio Bursts (FRBs), a
head-scratching phenomenon wanting of explanation.
-
- Columbus Day in 1992 was when NASA
initiated a formal, more intensive, SETI program.
How does the Universe work? How did we get
here? Are we alone?
-
- Scientists are now sifting through its
findings for possible technosignatures indicating an extraterrestrial
civilization. Planets are everywhere.
The “Kepler space telescope” served as the space agency's first
planet-hunting mission. During nine years of deep space scoping, it showed our
galaxy contains billions of exoplanets.
-
- A NASA-funded grant to a SETI Institute
scientist is using observations from the space agency's Transiting Exoplanet
Survey Satellite (TESS). The intent is to purge out of the TESS data possible
technosignatures aided by artificial intelligence/machine learning tools.
-
- Launched on March 6, 2009, the Kepler space
telescope became NASA's first mission to detect Earth-size planets in the
habitable zones of their stars. We
should begin to think about how we convey this information, possible impacts to
society, to religion, to politics, to technology, to governments.
