THE ULTIMATE
On this day, May 25th 240 BCE, Halley's Comet was first recorded in China, in the Records of the Grand Historian, or Shiji.
It may have been commented upon in Greece and China prior to this. A later recording in 87 BCE appears on Babylonian tablets that can be seen at the British Museum. Halley's comet is famously depicted in the Bayeux Tapeestry, having been seen by the Anglo-Saxons in 1066, and they saw it as a bringer of doom. It is called Halley's Comet, after Edmund Halley who in 1705, used Isaac Newton's laws of gravity and motion to calculate that three comet appearances, were actually the same comet returning around every 76 years. He went on to predict it would return in 1758. Unfortunatley, Halley died in 1742. Late in 1758 the comet returned first being seen by a German farmer and amateur astronomer. A French astronomer named it Halley's Comet after Edmund Halley. The return of Halley's Comet proved Isaac Newton's principles, and was the first object kown to orbit the Sun other than the planets. Though, the Babylonian and Jewish authorities in ancient times may have recognised that it returned, was 'periodic', as a passage notes a star returning once every 70 years. The last sighting of Halley's Comet was in 1986, where a European space probe named Giotto closed in on it flying through the comet's tail. It was called Giotto, after the artist who painted a Christian Nativity scene, using Halley's Comet, as the Star of Bethlehem. Next sighting 2061!
