1851 in science
- February – First public exhibition of a Foucault pendulum, at the Meridian of the Paris Observatory, demonstrating the Earth's rotation. A few weeks later Foucault installs one at the Panthéon.
- July 28 – Solar eclipse of July 28, 1851: Total solar eclipse. The first correctly exposed photograph, a daguerrotype, of the solar corona is made during the total phase of the eclipse by Berkowski at Koenigsberg Observatory in Prussia. Astronomers Robert Grant and William Swan (of the United Kingdom) and Karl Ludwig von Littrow (of Austria) observe this eclipse and determine that solar prominences are part of the Sun because the Moon is seen to cover and uncover them as it moves in front.
- October 24 – Ariel and Umbriel, moons of Uranus, were discovered by William Lassell.
- The William Brydone Jack Observatory is completed at Fredericton, New Brunswick.
