Astronomers knew something was wrong. Uranus was not moving exactly as expected, as though an unseen object in the darkness was pulling on it.
Instead of searching the entire night sky, mathematicians used gravity, orbital mechanics and careful calculations to predict where an unknown planet should be hiding.
Then some astronomers pointed a telescope toward that calculated position. And it was right there, Neptune.
This is the remarkable story of how mathematics revealed the existence of a world barely ever directly seen. And how Neptune later became one of the most mysterious planets explored by Voyager 2.
From a mathematical prediction to humanity's first close encounter with the far away blue giant, called Neptune.
