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