Is there life other planets? Are we alone? These are two the biggest questions humans have been asking centuries. Now, scientists have launched a new search to find if there is... anybody... there. The researchers are the SETI Institute in California. SETI stands Search for Extraterrestrial Intelligence. The mission SETI is, "to explore, understand and explain the origin and nature of life in the universe and the evolution intelligence". SETI scientists will use new technologies to scan the heavens signs of alien life. They will share their data the public. SETI hopes that by sharing data, "citizen scientists" could spot things missed scientists.
SETI's astronomers will use 28 giant radio telescopes their search for alien life. The telescopes are located all the world. It will be the first time that a project will search the entire sky signs of alien life. The signs they are looking for are called "techno-signatures". These include things alien chemicals, large amounts of oxygen, non-natural structures, and light lasers. Astronomer Dr Tony Beasley said: "Determining whether we are alone the universe as technologically capable life is among the most compelling questions science." Another scientist, Jill Tarter, said we are getting closer to finding if alien life exists. She said this science is now no longer fiction, but "almost mainstream".
