2016 was an exciting year for science and space exploration. Scientists reported earlier this year that Albert Einstein was right: there really are such things as gravitational waves that move through space. The discovery of a nearby planet has many people wondering if conditions there could be just right to hold life. Two other planets, Jupiter and Mars, also made the news. And, what is the possibility that “planet nine” really does exist far out in our solar system?
