Periodic Comet

Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading

What is the name of the largest planet

It happened because of that. the density of gases inside of it are incredibly low. Actually, in our Galaxy the number of stars is estimated at least 200 billion. White ovals on Jupiter limited circumferential zones. however, they can interact and form a region of chaotic clouds. On the Photo from a Space telescope named Hubble. made in ultraviolet rays. auroras appear as an annular zone around the poles of the planet. At the very least. its atmosphere is mostly hydrogen. The picture is composed of images. cameras made by Galileo using three filters. and shows. how it will look ancient rotating system of clouds. if you fly right over her. Most people go to work in the office. but my dream is to work at home.

Can you believe it. that many centuries ago.

The largest planet in the Solar system — Jupiter.

The largest planet of the Solar system The largest planet of the Solar system is.

Pluto is a planet or not. it was formulated the concept of determining Liberona the sky recently, a completely new object, a reddish point. which is very weakly visible. And that is what the scientist William Herschel was able to determine the rotation period of the planet. Instead of the Sun in our Solar system or somewhere on the outskirts. where it will not be visible. However by weight, it is second largest planet in three times. Continue reading

The history of cosmonautics

Space and Humanity

History of Astronautics – 098

The history of the space a number of times when on the road to further human exploration of outer space rose up high and seemingly insurmountable barriers. In 1961 the transition to weightlessness caused in perfectly healthy astronaut a painful condition similar to motion sickness. In 1966, after a three-week flight on the satellite “Cosmos-110” slightly alive returned to Earth two dogs. In 1970 it became clear that the meeting with Earth after 18-day stay in weightlessness is very difficult for humans. So there was a barrier of reparations, and the possibility of longer flights required further justification. In 1978, after a three-month flight is in the blood of an astronaut found atypical forms of erythrocytes, which suggests the appearance of weightlessness in a new generation of abnormal formed elements. In recent years, in connection with the implementation of the 7-8 series record-month flight appeared ideas about qualitatively new changes in the condition of the body in the postflight period, although not everyone agrees specialists.
