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

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.
Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.
But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading
Thanks to the flight to Pluto the earthlings had the opportunity to see a completely unknown distant world, but the planet itself asked scientists puzzle that requires resolution, said in an interview with radio Baltkom, the Russian astronomer who discovered the brightest comet of the decade ISON Artem Novichonok.
“We, first of all NASA employees,as well as all humans, had the opportunity to see a completely unknown distant world located on the outskirts of the solar system and he was totally not as what we expected. This world presents a lot of surprises and much more when the device will reset all data”, – said the scientist.
“First of all we are talking about data relating to the formation of the solar system in General and the formation of those distant objects, one of which is Pluto. Learning of this mission, we see a completely unusual structure, we see that the surface of Pluto and its satellite Charon are very young, suddenly, their bodies are very small, cold, much less the Earth and explain this geological activity is quite young mountains, the age of which children on the part of the solar system is very young, the plains are also very young, completely devoid of craters. All of these processes obyasnite does not work. Continue reading
