Numéro d’image : 12651477
| Illustration from the astronomer Johann Hevelius's The Celestial Machine from 1679, which he presented to Edmund Halley. Johannes Hevelius (1611-1687) was a Polish astronomer. He is remembered as the founder of founder of lunar topography, who also described ten new constellations (seven of which are still recognized by astronomers). In 1641 he built an observatory on the roofs of his three connected houses. He made observations of sunspots, 1642-1645, devoted four years to charting the lunar surface and discovered the Moon's liberation in longitude. He discovered four comets, in 1652, 1661, 1672 and 1677. These discoveries led to his thesis that such bodies revolve around the Sun in parabolic paths. His observatory, instruments and books were destroyed by fire in 1679. He promptly repaired the damage enough to enable him to observe the great comet of December 1680. His health had suffered from the shock of the 1679 fire, and he died on his 76th birthday. | |
