The Comet Hunter Who Predicted His Own Return
Edmond Halley studied a handful of historical comet sightings and made an audacious bet: they were all the same object, returning on a schedule. He staked his reputation on a prediction he would never live to see confirmed. This is the story of how one man turned a streak of light into a clock for the solar system.

Edmond Halley proved comets are single objects returning on long-period orbits rather than random celestial sightings.
Gravity from Jupiter and Saturn causes measurable delays in a comet's arrival by tugging on its path.
The seventeen fifty-eight return of the comet served as the ultimate trial for Newtonian physics.
Detection of cyanogen gas in nineteen ten triggered global panic and the sale of fake comet pills.
Spacecraft imagery reveals the comet is a dark potato-shaped body that vents dust and gas.
