Branch of Science Astronomers Nationality English Halley, Edmund (1656-1742) English astronomer who established the first observatory in the southern hemisphere on the island of St. Helena. He became good friends with Newton and convinced him to publish the Philosophiae Naturalis Principia Mathematica. In his "Ode to Newton," with which he prefaced the Principia, he wrote "Nearer the gods no mortal may approach" (Westfall 1988). After studying comets, he noticed that the path of the comets of 1456, 1531, and 1607 were surprisingly similar. He surmised that these three sightings were different apparitions of a single comet which he predicted would return again around 1758. He died before his prediction was tested, but the comet indeed returned and has been known as Halley's Comet ever since. When Flamsteed died in 1720, Halley was appointed Royal Astronomer at Greenwich Observatory. Flamsteed Additional biographies: MacTutor (St. Andrews) Bonn References Cook, A.

Halley, Edmond Anglický astronom, vybudoval první observatoø na jižní polokouli (ostrov Sv. Heleny). Zjistil, že parametry drah komet z let 1456, 1531 a 1607 jsou si velmi podobné. Usoudil, že jde o jedinou kometu a pøedpovìdìl její návrat v roce 1758. Zemøel ale pøed jejím pøíletem. Návrat Halleyovy komety v roce 1758 byl velkým triumfem Newtonovy mechaniky.

EDMOND HALLEY'S FAMOUS ADMONITION of 1716 PHILOSOPHICAL TRANSACTIONS VOL. XXIX (1716) A new Method of determining the Parallax of the Sun, or his Distance from the Earth; by Dr. Halley, Sec. R. S. N0 348, p.454. Translated from the Latin. which is the same thing, the sun's horizontal parallax, to be 12 seconds and a half, the moon will be less than Mercury, and the earth larger than Venus, and the sun's distance from the earth come out nearly 16500 semi-diameters of the earth. I shall admit of this distance at present, till its precise quantity be made to appear more certain by the trial I propose; not regarding the authority of such as set the sun at an immensely greater distance, relying on the observa-tions of a vibrating pendulum, which do not seem accurate enough to deter-mine such minute angles; at least, such as use this method will find the parallax sometimes none at all, and sometimes even negative; that is, the distance will become either infinite, or more than infinite, which is absurd. And it is scarcely possible for any one certainly to determine, by means of in-struments, however nice, single seconds, or even 10 seconds; and therefore, it is not at all surprising, that the exceeding minuteness of such angles has hitherto baffled the many and ingenious attempts of artists. But by the limited laws of motion, Venus is very rarely seen within the sun's disk; and for a series of 120 years, and upwards, is not to be seen there once; viz. from 1639, when Mr. Horrox was favoured with this agreeable sight, and he the first and only one since the creation of the world, down to 1761; at which time, according to the theories hitherto observed in the heavens, Venus will pass over the sun on May 26 in the morning; so that (vide Phil. Trans. N0 193) at London, nearly at 6 o'clock in the morning, she is to be in the middle of the sun's disk, and but 4 minutes more southerly than his centre. The duration of this transit will be almost 8 hours; viz. from 2 till near

Nov. 8 (Oct. 29, O.S.), 1656, d. Jan. 14, 1742, was an English astronomer who discovered the proper motion of stars and the periodicity of comets. His activities also ranged from studying archaeology to serving as deputy comptroller of the mint at Chester. He was an integral part of the English scientific community at the height of its creativity. A graduate of Oxford, he became a member of the Royal Society at the age of 22. From the island of Saint Helena, he catalogued (1676-78) the positions of about 350 Southern Hemisphere stars and observed a transit of Mercury; he urged that the latter phenomenon and future transits of Venus be used to determine the distance of the Sun. He worked out a theory of cometary orbits, concluded that the comet of 1682 (which still bears his name) was periodic, and correctly predicted that it would return in 76 years. In 1710, comparing current star positions with those listed in Ptolemy's catalog, he deduced that the stars must have a slight motion of their own, and he detected this proper motion in three stars.
