Neil deGrasse Tyson explains the possibility of alien civilizations existing in our galaxy the milky way.

Many people believe we've been visited by intelligent aliens but the evidence shown so far, is anything but overwhelming.

Since the first confirmed discovery of an exoplanet in 1995, astronomers have grown more confident that the universe must harbor other civilizations.

Their hope is to find other worlds with signs of microbial organisms or better yet, find evidence that would suggest the existence of intelligent extraterrestrial life.

The sheer number of stars suggests the universe is teeming with life.
