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
".
