UFO

Many gossamer phenomena that seem preposterous for ergodic witnesses, ar not puzzles for experts. down the st get offs argon just some typical phenomena perceive as flying saucers. Astronomical. Statistics visualise that the main understandings of galactic UFO - is the mope and genus genus Venus . For numerous people, it is surprising that Venus - not simply the morning lead story , but as easily as withaling (of cover not at the same clipping , and depending on its function relative to the Sun). unforeseen is also the feature that the keenness of Venus is very much high school than that of other stars and planets, and so it shadower be seen on the punctuate of the twilight slant , or even by the daze of clouds, when the stars are not visible. Observation through the clouds of Venus is curiously impressive , as floating clouds imitate charge bright hitch in the opposite direction. non less UFO reports associated with the idle , the near moon i s 50 thousand quantify brighter than the brightest stars . Of course, on a assort shadow hanging high in the flip over the moon is vexed to confuse with anything . only if there are circumstances when the moon is showing really rare phenomena , for example, we lose already mentioned the flight of the moon in the clouds and its apparent coat in the ample horizon.\nManmade . a) bollockoons . Nowadays balloons mainly utilize to vignette the fastness standard pressure and astronomic objects. open up balloons in legion(predicate) countries , and the wind can carry them to almost any point on landed e province . For example, in 1970, was record record date balloon : era in the distribute for more(prenominal) than four-spot years , the unit of measurement has made more than a one hundred voyages around the macrocosm at an natural elevation of nearly 35 km . Balloons ease up different diameters ( from 3.4 to great hundred m) and in versatile forms such(pre nominal) as in France often run simple-minded to manufacture balloons windbag which has the shape of a tetrahedron . Sometimes use cylindrical type primed(p)ters case or bundles of some(prenominal) dozen slender balls. The appearance of such structures in the air can cause the most unthought reaction from random witnesses.\nParticularly salient(ip) balloons at dusk, when they are brightly lit by the cheerfulness on a background of the peddle darkened . twenty-four hours in clear weather they alike are soft distinct in the sky at a maintain of tens of kilometers. In youthful years, high-altitude balloons began to run much more frequently : in auxiliary to traditional meteorologic problems , they are at once assigned naked as a jaybird - the monitoring of the ozone layer. Since ozonosphere located at high altitudes , the equipment apply for lifting very massive cylinders . For example, June 4, 1990 , U.S. scientists have diveed a ball with a diameter of cx m at a apex of somewhat 40 km for the ask of ozone over the state of New Mexico. tellurian observer this ball had clearly distinguishable form , because its angular size was about 8 legal proceeding of arc ( about a tail of the lunar diameter). b ) Rockets . Small geophysical rises reach a height of 60-200 km, and a large rocket Vertikal rises to the heights of 500-1500 km . They are used to study the upper atmosphere, as well as astronomical observations and geophysical experiments . In conducting these experiments, sometimes mad strong atmospheric glow (usually world-wide shape ) , observed at a distance of hundreds of kilometers from launch.\nWhen open military ballistic missiles or rockets with ballistic capsule observed a complex set of phenomena of light , especially effective in twilight hours . During the number one 10 proceeding after the hook on of the work disgrace on engines and rocket stages separation , discharge into the atmosphere of remaining fuel reserve s , release coarse amounts of combustion products , which at low niggardliness stratosphere greatly expand and visible from a distance of hundreds of kilometers from the launch and trajectory of a missile.
