Scientists are finding new planets and views into the deepest reaches of space, breaking new ground in understanding the universe and its mysteries. In this new season, viewers are transported to new and mysterious places including ones we didn't even know existed a year ago -- some harboring deadly forces that may forever impact life on Earth.
