When Pushkar Ganesh Vaidya says, “There is something terribly wrong, as we are not able to find aliens, they should have been here already,” you might want to believe him. After all, he’s an astrobiologist heading the Indian Astrobiology Research Centre (IARC) — dedicated to the study of the origin, evolution and distribution of life in the universe. Their study also includes the search for the elusive extraterrestrials — and has been involved in research work on microbial life across universe since 2001.
