5th Search for Life Signatures Symposium Print
International Academy of Astronautics
5th IAA Search for Life Signatures Symposium
March 20-21, 2014
Paris, France



Conference report and final program are available.


 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”.

In recent years, a new kind of SETI, called “Active SETI”, has been discussed by radio astronomers and has been attempted in a few cases: it consists of deliberately transmitting signals to enhance the probability of making contact with other hypothetical galactic technological civilizations. In addition, the discovery since 1995 of more than 2000 extrasolar planets makes it clear that both Passive and Active SETI may now be “targeted” towards exoplanets that are situated within habitable zones, further increasing the probability of a SETI success.

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 both Passive and Active SETI. These are the goals of the “Searching for Life Signatures” Conference that will take place at UNESCO in Paris, March 20-21, 2014, at the occasion of the Spring Meetings (March 17-20) of the IAF, IAA, IISL and COSPAR in view of the 2014 International Astronautical Congress (2014 IAC) that will be held in Toronto, Canada, September 29th thru October 3rd, 2014.
