The bombardment of comets

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.

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 discoverer of the ninth planet

DWARF PLANET

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
