Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

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

Something beyond Neptune

Astronomers have discovered the 9th planet of the Solar system?

Giant in the Kuiper belt

Perhaps, the ideas of humans about the Solar system far from reality. Scientists from the University of California, Michael brown and Konstantin Batygin has published a paper in which it is proved that in the Solar system there is at least one full planet .

For the first time sensational work of scientists was published in The Astronomical Journal, later it was reported by reputable scientific journals Science and Nature.

As stated in the work, a new planet, still do not have own names, was found by mathematical analysis of perturbations that experience the body the so-called “Kuiper belt” — space on the outskirts of the Solar system.

According to the calculations of brown and batygina, the ninth planet orbit is at a distance of 20 orbits from Neptune. Revolution around the Sun, this object travels in 10 – 20 thousand years. Planet, according to the findings of researchers exceeds the Land mass 10 times. Continue reading

Cosmonauts day

April 12, Russia celebrates cosmonautics Day. This holiday was established by the decree of the Presidium of the Supreme Soviet on 9 April 1962 in honor of the world’s first manned flight into space.

April 12, 1961 in earth orbit was launched the world’s first spaceship‑satellite “Vostok” with a man on Board. The launch of the first manned space craft was headed by Sergei Korolev, Anatoly Kirillov, Leonid Voskresenskiy.

Pilot‑cosmonaut of the ship was a Soviet citizen pilot major Yuri Gagarin. The start of the space multistage rocket was successful and after the set speed and separation from the last stage of the carrier rocket, the ship began a free flight on an orbit around the Earth.

After circling the globe, through 108 minutes after launch, was included braking propulsion system and the spacecraft‑the satellite began to descend from orbit to landing. In 10 hours 55 minutes Moscow time the astronaut landed in a given area of arable land in the Volga river near village of Smelovka in the Ternovsky district of the Saratov region. Continue reading
