alien life by finding complex molecular structures from samples collected in space.And life-detection instruments can now be sent on space missions to search for complex lifeforms with a view to cloning them in laboratories.Glasgow University’s Professor Lee Cronin said: “Only living systems can produce complex molecules that could not form randomly in any abundance. “This allows us to sidestep the problem of defining life – instead we focus on the complexity of the chemistry.” The Glasgow uni team collaborated with Nasa and Arizona State University on the system.But cells collected by Nasa’s Mars lander contained only simple molecules.Ex-US President Barack Obama last week said the world should take UFOs seriously after US pilots were.
