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
100 kilometers above the Earth’s surface (according to the international standards space begins at this altitude), speed – kmh 4000, which is 4 times the speed of sound, so it looks like a tourist flight into space, which you could see in sci-Fi movies or dreamed about since childhood.
Now the dream to see the immensity of outer space has already become a reality.
Who are those 5 people who first saw the Galaxy, read the article. We will also talk about the details of the flight and to quote the impressions of space explorers.
Space tourists – Dennis Anthony Tito

This reckless American with a decidedly non-American name proudly bears the title of “space tourist No. 1”. Anthony Tito is a multimillionaire and entrepreneur of Italian origin. Continue reading
Jupiter, the fifth in distance from the Sun and the largest planet in the Solar system – distance from Sun-5.2 times further than Earth, and spends some turnover on orbit for almost 12 years. Equatorial diameter of Jupiter is 142 600 km (11 times the diameter of the Earth). The period of rotation of Jupiter is the shortest of all the planets – 9 h 50 min 30 s. at the equator and 9 h. 55 min. 40 s. in the mid-latitudes. Thus, the Jupiter, like the Sun, rotates as a rigid body – rotation speed varies in different latitudes. Because of the rapid rotation of this planet has strong compression at the poles. The mass of Jupiter is equal to 318 Earth masses. The average density of 1.33 g/cm3, which is close to the density of the Sun. The rotation axis of Jupiter is nearly perpendicular to the plane of its orbit. Even in a small telescope shows the polar compression of Jupiter and bands on its surface parallel to the equator of the planet
The Structure Of Jupiter
The visible surface of Jupiter is an upper level clouds surrounding the planet. This ensures that all details on the surface of Jupiter is constantly changing its appearance. From sustainable parts known Great Red spot, observed for over 300 years. It is a huge oval formation, the size of about 35,000 km in longitude and 14000 in latitude between the southern tropicheskii southern temperate bands. Continue reading
