Possibly, comets brought water to Earth
To see exactly what is in the comet, it is necessary to analyse its substance with the help of different high sensitive devices, bringing samples to Earth. But aboard a small spacecraft such devices are difficult to place, because the size of the station Stardust 1,7×0,7×0,7 meters – about the same size as the Desk. How to take a sample of matter, flying from the comet’s nucleus at high speed? Space standards Stardust was moving slowly relative to the comet, about one and a half times slower than fly around the Earth artificial satellites. However, even this speed was several times greater than that of the bullet, the station flew over one second 6 km from the Contact of dust particles with the container of solid material at this speed (more than 20 thousand km/h) would have led to their strongest heating and evaporating. The only way to mildly catch and stop these dust particles, turned out to be a trap made of unique material – aerogel, which was established in 1931, but the big distribution has not received.

They dived to the bottom of hell, under the thick neon-methane atmosphere of Pluto. Flew in the snow storms of ammonia, every second fearing a break in the dark about huge needles durable as steel, water ice. They managed to find an area where there are mountains. The mystery of Pluto has been solved at last — this planet belongs to our Solar system. She captured her during the journey of the Sun through the Galaxy.

SEARCH OF THE WANDERERS
Amateur astronomer William Herschel, discoverer of Uranus
The discovery of Pluto, which for a long time officially considered the ninth planet of the Solar system, has its own history. Before the advent of telescopes humanity were well known five celestial bodies called planets (from the Greek for “Wanderers”, “wandering”): mercury, Venus, Mars, Jupiter, Saturn. During the four following centuries managed to open two more major planets, Uranus and Neptune. Continue reading
Star line-up. As you know, these days several planets in the solar system lined up in one line. This so-called parade of planets. In Irkutsk cosmic phenomenon, of course, interested professionals and Amateurs to observe the Universe.
Fans of star observations go in pursuit of planets in the early morning. Every minute counts. Dawn is inexorably approaching. Even a small glow can ruin the expedition. In the suburbs of Irkutsk the best place for astronomical observations — the village of Maksimovschina. There is a good elevation away from the city. At five o’clock in the sky appears the first star of the big parade of planets. Despite the early hour and freezing temperatures, people came here by families with young children.
— Parade of planets happens once in a lifetime. At least see the time. Star-gazing, says participant observations Dmitry Bakers.
Organizes the monitoring of the Irkutsk planetarium. Brought two powerful telescope. With their help, you can enjoy a stunning view of space in all its glory. Thanks frosty air clearer picture. Continue reading
