TASS: Space – the Comet Churyumov

Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun

Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.

According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading

The structure of comets

Unlike planets, comets move on highly elongated orbits, and therefore are visible only at short periods close to the Sun.

The main part of any comet is its nucleus .

According to the hypothesis of the famous American researcher of comets Fred Lawrence Whipple, cometary nucleus is an ice consisting of a mixture of frozen water and frozen gases interspersed with refractory rocky and metallic particles . Figuratively speaking, it looks like a “dirty iceberg”.

Let us imagine that we see the newly opened the comet, which is somewhere in the vicinity of Jupiter’s orbit. Seeing through the telescope hazy pale speck, like a spherical nebula (such unattractive are presented to the observer of a distant comet), we may be disappointed at first. With the approach of the comet to the Sun the solar flux increases. Comet “ice” begin to evaporate rapidly. Around the nucleus formed a vast glowing gas shell – coma. Together with the core of it is the head of the comet. Continue reading

Planets of the solar system.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

A planet is a celestial body that must satisfy four conditions:

1. the body must revolve around the star (for example, around the Sun);

2. the body must have sufficient gravity to have a spherical or similar shape;

3. the body should not be near its orbit of other large bodies; Continue reading
