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
Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.
Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.
The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:
Ice (water, ammonia, methane, carbon dioxide)
Some organic materials (e.g., resin)
Rocky ground (optional) Continue reading
