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
The period of rotation around the Sun
Of 11.86 earth years
The first “date” earthly messenger with the giant of the Solar system – Jupiter was held in late 1973. Still on approach to Jupiter by “pioneer 10”, began to transmit color images of the planet Earth. On the screens in the mission control Center dynamic unfolding panorama of the approaching giant striped. Bright stripes on Jupiter are like ridges over high and cold clouds. And Vice versa: the dark stripes are the valleys between the ridges. Among the atmospheric lanes of the South tropical zone “blazed” the bright colors of the famous Great Red Spot.
Further large-scale image of this amazing education received by “Voyager-1” (the highest resolution on the images was 5 km), allowed us to understand the complex meteorology of Jupiter. It turned out that the mysterious spot has a clearly visible vortex structure: this is a floating disturbance in the atmosphere, in other words, a huge atmospheric vortex. In the spot, there is a rise of the substance and spreading it from the center. Continue reading
