EXTRATERRESTRIAL life may well be so weird we would not immediately recognise it, space experts said yesterday.
Scientists looking for alien life should be seeking the unfamiliar as well as the familiar, they said.
NASA's current approach to "follow the water" is logical assuming alien life is comparable to that on Earth - based on water, carbon and DNA - but the "life as we know it" approach could easily miss something exotic, the US National Academy of Sciences panel advised.
"The purpose of this whole report was to be able to look for life on other planets and moons with an open mind ... and not maybe miss some other life form because we are looking for some obvious life form," said John Baross, professor of oceanography at the University of Washington in Seattle, who chaired the committee.
