6th IAA Symposium on Life Signatures

International Academy of Astronautics
6th IAA Symposium on
Search for Life Signatures
March 26-27, 2015
Paris, France



Conference report is available.

The 6th IAA Symposium on Search for Life Signatures is organized by the International Academy of Astronautics (IAA) and is co-sponsored by ASTRON

SETI (the “Search for ExtraTerrestrial Intelligence”) refers to the experiments intended to find either radio or optical signals from extraterrestrial societies situated on planets around other stars. The largest radio telescopes world-wide have occasionally pursued SETI searches since 1960, in most cases hunting for signals near in frequency to 1420 MHz (the emission line of neutral hydrogen). Optical SETI searches have been pursued since the 1990s. These attempts to detect extraterrestrial signals are called “Passive SETI”.

The discovery since 1995 of more than 2000 extrasolar planets makes it clear that SETI may now be “targeted” towards exoplanets that are situated within habitable zones, further increasing the probability of a SETI success. But many other possibilities are now widening the SETI horizon also. We might conduct SETI searches in the UV, X or gamma range, in addition to the already existing searches in the radio and optical range. Nor should we forget about the possible Neutrino SETI and Gravitational Waves SETI. And ET Civilizations might live not just on extrasolar planets, but also on their moons or even in space colonies. So, intercepting an ET message might become a matter of intercepting telecommunications from moving spaceships, whether or not relativistic. Even SETV, the Search for proofs of ExtraTerrestrial Visitations within the Solar System, should not be ruled out.

In conclusion, it is now timely to gather a large conference of experts in SETI, biosignatures, the search for terrestrial exoplanets and related disciplines from all over the globe to openly discuss the strategies of SETI. These are the goals of the 6th IAA Symposium on “Search for Life Signatures” that will take place in Paris, March 26-27, 2015. This will be just immediately after the four-day Paris Spring Meetings (March 23-26) of the IAF, IAA, IISL and COSPAR in view of the 2015 International Astronautical Congress (2015 IAC) that will be held in Jerusalem, Israel, October 12th thru 16th, 2015.


Preliminary program is available.
