How old is the oldest planet? When did the first planets form in the universe? And what about life-supporting worlds? These are some of the most complex questions in extrasolar-planetary science. But by studying the ancient exoplanets in the Milky Way galaxy, we've managed to build up a comprehensive picture of when the genesis planets formed, and what they were like. Those findings make up the content of our video today.
