• November 27 – John Michell proposes the existence of black holes ("dark stars").
• Jérôme Lalande publishes a revised edition of John Flamsteed’s star catalogue in an ephemeris, Éphémérides des mouvemens célestes, numbering the stars consecutively by constellation, the system which becomes known as "Flamsteed designations".

Aviation

• June 5 – The Montgolfier brothers send up at Annonay, near Lyon, a 900 m linen hot air balloon as a public demonstration. Its flight covers 2 km and lasts 10 minutes, to an estimated altitude of 1600–2000 metres.
• August 27 – Jacques Charles and the Robert brothers launch the first hydrogen balloon in Paris.

• Erasmus Darwin begins publication of A System of Vegetables, a translation of Linnaeus in which he coins many common English language names of plants.

Chemistry

• Antoine Lavoisier publishes Réflexions sur le phlogistique, showing the phlogiston theory to be inconsistent, proposing chemical reaction as an alternative theory in a paper read to the French Academy of Sciences in June, names hydrogen and demonstrates that water is a compound and not an element.
• Discovery of tungsten – José and Fausto Elhuyar find an acid in wolframite which they reduce with charcoal to isolate tungsten.

Earth sciences

• February 5–March 28 – Calabrian earthquakes in Kingdom of Two Sicilies.
• June 8 – The volcano Laki in Iceland begins a major eruption with extensive climatic consequences on both sides of the Atlantic Ocean.
• August 4 (Edo period, Tenmei 3) – Mount Asama, the most active volcano in Japan, begins climactic eruption, exacerbating a famine, following a plinian eruption beginning on May 9 (Tenmei eruption).

History of science and technology

• German physician Melchior Adam Weikard publishes a biography of microscopist Wilhelm Friedrich von Gleichen, Biographie des Herrn Wilhelm Friedrich v. Gleichen genannt Rußwurm.

Physics

• Jean-Paul Marat publishes Mémoire sur l'électricité médicale ("Memorandum on Medical Electricity").

Technology

• Henry Cort of Funtley, England, invents the grooved rolling mill for producing bar iron.
• Thomas Bell patents a method of printing on fabric from engraved cylinders.
