Australian scientists say they've figured out why we've been unable to detect signs of alien life. And for those who dream of someday meeting up with a real-life E.T., it's a pretty depressing reason.

"Early life is fragile, so we believe it rarely evolves quickly enough to survive," Aditya Chopra, an astrobiologist at Australian National University in Canberra and lead author of the paper, said in a written statement. In other words, it succumbs to temperature extremes long before it has a chance to evolve beyond the microbe level.
