Is there life on other planets? Are we alone? These are two of biggest questions humans have been asking for centuries. Now, scientists have launched new search to find out if there is... anybody... out there. researchers are from SETI Institute in California. SETI stands for Search for Extraterrestrial Intelligence. mission of SETI is, "to explore, understand and explain origin and nature of life in universe and evolution of intelligence". SETI scientists will use new technologies to scan heavens for signs of alien life. They will share their data with public. SETI hopes that by sharing data, "citizen scientists" could spot things missed by scientists.

SETI's astronomers will use 28 giant radio telescopes in their search for alien life. telescopes are located all around the world. It will be first time that project will search entire sky for signs of alien life. signs they are looking for are called "techno-signatures". These include things like alien chemicals, large amounts of oxygen, non-natural structures, and light from lasers. Astronomer Dr Tony Beasley said: "Determining whether we are alone in universe as technologically capable life is among most compelling questions in science." Another scientist, Jill Tarter, said we are getting closer to finding out if alien life exists. She said this science is now no longer fiction, but "almost mainstream".
