Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. July 6, 1996 Edmond Halley's Greatest Discoveries Explanation: Sir Edmond Halley was quite a discoverer. Born in 1656, he computed in 1705 that a bright comet was periodic and would make another appearance in 1758. The comet appeared as predicted and is now known as Comet Halley . Unfortunately, Halley died in 1742 and never saw his prediction come true. In 1716 Halley proposed two types of diving bells that would enable people to explore the deep sea. Halley pioneered our understanding of trade winds, tides, cartography, naval navigation, mortality tables, and stellar proper motions. Halley (incorrectly) proposed that the Earth was made of concentric spheres the size of the inner planets each of which might contain life. Perhaps Halley's greatest discovery, however, was that his contemporary Isaac Newton had discovered a powerful mathematical formulation of gravity.

Born on November 8, 1656 in Haggerston near London, HALLEY went to St. Paul’s School in London, started his studies at Queen’s College in Oxford and in 1676, without finishing his studies, he went for 18 months to the island of St. Helena in order to survey the positions of the fixed stars of the southern hemisphere. He went back to London and received his Master’s degree and was accepted as member in the Royal Society. He maintained a life-long friendship to NEWTON, whom he motivated to write and publish the ‘Principia’. From 1698 to 1700 he was sent by the British Admirality on two research journeys to Africa and America down to the southern border of the ice belt, in order to measure magnetic declination in many different places. After he returned, he was appointed Professor of Geometry in Oxford, and in 1720 he was appointed Royal Astronomer. He died on January 14, 1742 in Greenwich. He was the first to defend the hollow- sphere theory of the interior of the Earth that influenced the idea of chemical causes of earthquakes by HUMPHREY DAVY. document last modified (mm/dd/yyyy):

Sir Edmond Halley Sir Edmond Halley (1656 - 1742) era un astronomo inglese, conosciuto soprattutto per i suoi studi sulle comete , e per la sua scoperta che alcune comete osservate nei secoli precedenti sembravano aver percorso orbite simili. In particolare, notò che le comete del 1531, 1607 e 1682 sembravano simili e ipotizzò che in realtà si trattasse della stessa cometa periodica. Predisse che la cometa sarebbe riapparsa nel 1758; quando venne effettivamente osservata, dopo la morte di Halley, la cometa fu da allora chiamata con il suo nome.

IN VIRI PRAESTANTISSIMI ISAACI NEWTONI OPUS HOCCE MATHEMATICO-PHYSICUM SAECULI GENTISQUE NOSTRAE DECUS EGREGIUM. Pangeret, omniparens leges violare creator Noluit, atque operum quae fundamenta loc’rit. Intima panduntur victi penetralia caeli, Nec latet extremos quae vis circumrotat orbes. Sol solio residens ad se jubet omnia prono Tendere descensu, nec recto tramite currus Sidereos patitur vastum per inane moveri; Sed rapit inmotis, se centro, singula gyris. Jam patet horrificis quae sit via flexa cometis; Jam non miramur barbati phaenomena astri. Discimus hinc tandem qua causa argentea Phoebe Passibus haud aequis graditur; cur subdita nulli Hactenus astronomo numerorum fraena recuset: Cur remeant nodi, curque auges progrediuntur. Deserit, ac nautis suspectas nudat arenas; Alternis vicibus suprema ad littora pulsans. Quae totiens animos veterum torsere sophorum, Quaeque scholas frustra rauco certamine vexant, Obvia conspicimus, nubem pellente mathesi. Jam dubios nulla caligine praegravat error, Queis superum penetrare domos atque ardua caeli Scandere sublimis genii concessit acumen.
