Comet Halley, of course, the most popular of comets.During the last appearance of the comet in 1835. by spectral analysis revealed that the composition of cometary atmospheres observed molecular bands cyanide, carbon monoxide and other compounds.So quickly spread rumors about poisoning the earth`s atmosphere harmful to human health comet poisonous gases.As predicted by astronomers, the Earth May 19, 1910.
"Confronted" with the tail of Halley`s Comet.However, even the most sensitive instruments have not detected any unusual phenomena in the Earth`s atmosphere, which could be uniquely associated with this event.So the wave of fear swept through many countries in May 1910. , Did not have under any foundation.After passing through the tail of Halley`s comet, the Earth has played the role of a probe.
It should be noted that the Earth has been repeatedly passed through the tails of comets and the effect was always the same - no effect on the processes in the Earth`s atmosphere the substance of various comet tails will not help.Astronomers and many inhabitants of the Earth closely monitor all the changes taking place in the tail and the head of Halley`s Comet.
Over the entire period of observation had been received over a thousand of its astronegativov, over hundreds of spectrograms, many hundreds of pictures of a comet and a large number of definitions of its equatorial coordinates at different points in time.All this wealth of material allowed to study in detail the motion of the comet in its orbit to explore the types, structural features, chemical composition of its head and tail, as well as a number of other physical parameters of the comet`s nucleus and its surrounding atmosphere.
Beneficiaries learned even in the arts.And in Europe and in Russia, several artists depicting the celestial object can be clearly seen almost the entire month with the naked eye.Comet Halley - the only short-period comets, easily visible to the naked eye.
Last perihelion was in February 1986. And the next is estimated to be in mid-2061. |
