Nevertheless, the evil label stuck long comets. To the dismay of scholars of the Renaissance and modern times who were interested in their nature. In 1773, discovering the people panic, Voltaire was indignant: "All Paris, finally, was in alarm, he was convinced that a comet would dissolve our globe on 20 or 21 May" . And what was the amazement of the astronomer Camille Flammarion , nearly two centuries later, that - despite the brilliant work of Halley and Newton and a 19 th marked by important scientific discoveries century - attending terror of his fellow citizens. http://enjoycoloring.com/ They imagined, in fact, die poisoned by the famous Halley's Comet , during his visit scheduled for May 1910 between the Earth and the Sun . The astronomer did not imagine similar reactions when, a few years earlier, he observed "the presence of cyanogen gas" in the atmosphere and tail of the comet. Of course, the big floods that gripped the French capital that year were attributed to the phenomenon.
Not sure that even today, the superstitions of the same type are permanently silenced. Witness the countless false rumors peddled on the Internet , around these stars .
On the traces of our origins
Having described, during the XVIII th century, the orbit of the comet and successfully predicted their returns, astronomers are more interested in their nature and origin. Thus, in the footsteps of Emmanuel Kant, Pierre-Simon Laplace in 1805 took the idea of a gravitational collapse of a primordial nebula to explain the formation of the Sun and planets to which they were related. Short periods orbital observed suggested that they belong to the solar system and not to the interstellar medium.
It was around 1872 that the relationship was established between of rain stars shooting ( meteor swarm ) and these stars hairy spot. History teaches us that at the beginning of the XIX th century, the comet Biella, whose orbit was 7 years old, was observed several times until its division into two corpuscles in 1846. its passage in 1852, those -Ci appeared fragmented and finally, twenty years later, on the anniversary of his visit, a meteor shower succeeded!
