Mankind will make contact with alien life far earlier than you might think, according to a prominent researcher.
Nobel Prize winner Professor Didier Queloz says he is convinced that we are not alone in the universe and that he believes we could find life on another planet within 30 years.
The Swiss astronomer, 53, works at the University of Cambridge and was one of three researchers awarded the Nobel Prize in physics this week.
Speaking in London on Tuesday, he said: "I cannot believe that we are the only living entity in the universe. There are far too many planets, far too many stars and chemistry is universal. "
" The chemistry that led to life must happen elsewhere. "
Queloz added that he is certain alien life will have been discovered from Earth within the next century.
However, he said it is realistic that a machine capable of detecting biochemical activity on distant planets could be built within 30 years. [1
A machine that detects biochemical activity at a distance would give experts the opportunity to find life at a great distance. about time until we get a positive hit.
Queloz shared this year's Nobel for Physics with fellow and fellow Swiss professor Michel Mayor.  They were honored to find an exoplanet orbiting a solar-like star.
Mayor and Queloz started a revolution in astronomy when they discovered 51 Pegasi B, a gaseous ball comparable to Jupiter, in 1995.
The discovery was made at a time when, as the mayor recalled, "no one knew if exoplanets existed or It was "the first step in our search for" Are we alone? "said astronomer Dr. Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell University.
More than 4,000 exoplanets have been found since in the Milky Way and scientists believe that one in four or five stars has planets.
"We have 200 billion stars out there in our galaxy alone, so I like our chances," Kaltenegger said.
