Solved cryptogram
Neptune was found with mathematics first. Its position was worked out before a telescope saw it.
Astronomy Facts, sourced to NASA.
What it means
Uranus was not following the orbit that Newton's laws predicted, and two mathematicians independently concluded that an unseen planet must be tugging on it. Urbain Le Verrier sent his calculated position to an observatory in Berlin, and the planet was spotted the same night, within a degree of where he said it would be. It was a triumph for gravitation as a predictive theory.
The claim comes from NASA, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
