According to a lead British astronomer, Lord Martin Rees, within the next 40 years, it will be possible to discover alien life in other solar system.
A report published by a British daily recently informed that astrophysicists, with the aid of new technologies, are most likely to view images of distant planets outside our solar system in near future.
Rees seems quite sure that within a few decades, scientists will be able to image other planets like the earth around other distant stars and discover extra-terrestrial intelligent life.
