Halley’s comet is the only short-period comet that is clearly visible to the naked eye
Halley’s comet is the most popular of comets. It rotates around the Sun with a period of 74 to 79 years in highly elliptical orbit. During the appearance of the comet in 1835 with the help of spectral analysis it was found that the composition of cometary atmospheres observed molecular bands of CYANOGEN, carbon monoxide and other compounds. So quickly spread rumors about poisoning the earth’s atmosphere hazardous to human health toxic cometary gases.
As predicted by astronomers, may 19, 1910 the Earth “collided” 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 uniquely associate with this event. So the wave of fear that swept through many countries in may 1910, had under itself no soil.
After passing through the tail of Halley’s comet, the Earth appeared as a kind of 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 influence on processes in the earth’s atmosphere substance of different tails of comets were not provided.

NASA scientists have discovered the Solar system’s tail, like a comet “Tail” of the Solar system, consisting of a flow outgoing from the Sun fast-moving charged particles, shaped like a four-leaf clover. The length of the plume is still unknown. The Solar system turned out to be the tail, NASA
American scientists have found that the Sun moves in space, leaving behind a tail like a comet .
These unique data obtained by the NASA experts. the guiding mission of the IBEX spacecraft, ejected into orbit five years ago.
The probe instrument helped astronomers to see two streams of charged particles coming from the poles of the Sun. Two more flow out on the sides of the star, so her tail resembles a four-leaf clover, NASA said.
Previously, the tailings were observed in some stars, but the fact that it has and our Central luminary, became for scientists a complete surprise. As far as the long tail of the Solar system, astrophysicists still can not say. Continue reading
Comets are Solar system bodies having the form of vague objects, usually with pale clot kernel in the center and tail. They are among the most beautiful celestial bodies. hazy Bright shell surrounding a core of hazy, long tail, extending sometimes to half the sky, fast motion among the stars – all this makes comet different from other heavenly bodies. The comet can be observed when a small ice body, called the nucleus of the comet is approaching the Sun at a distance that is less than 4-5.e. warmed by the sun, and it begins to stand out gases and dust that are visible as a result of their illumination by the Sun.
Gases and dust released from the nucleus, creating around him a hazy shell – atmosphere of the comet, components along with the core of the head of the comet. The atmosphere of a comet continuously dissipates in interplanetary space: under the action of radiation pressure and interaction with the solar wind gases and dust are carried away in the direction from the Sun forming the comet’s tail.
Most of the comets in the middle of the head there is a bright star-like “core”, representing the illumination of the Central, most dense zone of true gases around the comet’s nucleus. Continue reading
