29 giu 2024 · Il famoso astronomo che aveva dato il nome la maestosa cometa. che ogni 76 anni solca il cielo terrestre morì 14 gennaio del 1742. Lo sapeva sin dall’inizio, Edmond Halley, che non avrebbe fatto in tempo a osservare un nuovo passaggio della cometa che oggi porta il suo nome e a verificare così l’esattezza della sua teoria.
28 giu 2024 · Halley’s Comet, the first comet whose return was predicted and, almost three centuries later, the first to be imaged up close by interplanetary spacecraft. In 1705 English astronomer Edmond Halley published the first catalog of the orbits of 24 comets.

2 giorni fa · Ultimately, it was Newton's friend, editor and publisher, Edmond Halley, who, in his 1705 Synopsis of the Astronomy of Comets, used Newton's new laws to calculate the gravitational effects of Jupiter and Saturn on cometary orbits.
6 giorni fa · EDMUND HALLEY was a very great man. He was not only the first to predict correctly the return of a comet, that which is now known by his name, but also—before Newton had announced his results to...
10 lug 2024 · Edmond Halley reported it as a nebula in 1677, and in the 1830s the English astronomer John Herschel was the first to recognise it as a globular cluster. Globular clusters typically consist of up to one million old stars tightly bound together by gravity and are found both in the outskirts and central regions of many galaxies ...

1 giorno fa · In 1684, both Hooke and Newton told Edmond Halley that they had proven the inverse-square law of planetary motion, in January and August, respectively. While Hooke refused to produce his proofs, Newton was prompted to compose De motu corporum in gyrum ('On the motion of bodies in an orbit'), in which he mathematically derives Kepler's laws of planetary motion .
