London: Aliens could be operating through sentient robots and the hunt for extraterrestrial life should take this possibility into account, a leading astronomer has said.

Seth Shostak, of the Search for Extraterrestrial Intelligence (SETI) Institute in California, said humans had a greater chance of picking up signals from alien-operated robots than from the biological lifeforms that had created them.

The quest to find alien life so far has generally followed standard rules of biochemistry, working on the assumption that detectable extraterrestrial beings would be biologically "alive".

But Dr Shostak said astronomers may be overlooking the existence of "sentient machines" from outerspace, the Telegraph reported.

The astronomer argued that while evolution can take a large amount of time to produce beings capable of inter-planetary communication, technology could advance fast enough to move beyond the species that created it.

"If you look at the timescales for the development of technology, at some point you invent radio and then you go on the air and then we have a chance of finding you," he said.

"But within a few hundred years of inventing radio -- at least if we're any example -- you invent thinking machines.

Founded in 1984, the SETI institute has the mission to explore, understand and explain the origin, nature and prevalence of life in the universe.
