How the Universe Works Season 8

Science Channel's signature space series is beaming back up after the new year for a new season of out of this world mysteries. HOW THE UNIVERSE WORKS returns for its eighth season with a two-hour special on Thursday, January 2 at 9 p.m. ET that investigates the threat of a catastrophic asteroid impact. While asteroids have hit us before and will most certainly hit us again, predicting how big the next direct impact will be and where it will land remains incredibly difficult. A perfectly placed hunk of rock or metal coming from outer space could potentially trigger the end of life on Earth.
