Paragraph 2
						  
SETI's 
 will use 28 
 radio telescopes in their search for alien 
. The telescopes are located all around the world. It will be the first 
 that a project will search the entire 
 for signs of alien life. The signs they are looking for are called "techno-signatures". These include 
 like alien chemicals, large amounts of oxygen, non-natural structures, and 
 from lasers. Astronomer Dr Tony Beasley said: "Determining whether we are alone in the universe as technologically capable life is among the most compelling 
 in science." Another scientist, Jill Tarter, said we are getting 
 to finding out if alien life exists. She said this science is now no longer fiction, but "almost 
".
