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

The planet Jupiter

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

Philae returned the first detailed images of the comet Churyumov-Gerasimenko

Wednesday night, the Earth reached the signal from the research module Philae successful landing on the comet Churyumov-Gerasimenko. Unique in its complexity maneuver succeeded at the first attempt. Experts from the European space Agency outfitted the robot in the path 10 years ago. During this time the device has traveled more than six billion kilometers. The data collected, according to scientists, may shed light on some puzzles of the Solar system.

Almost 7 hours of intense expectation, and now scientists from the European space Agency’s congratulate each other with applause. The descent module landed on the comet. Or, saying a new term, “picometers”.

“Undoubtedly, we have lived this mission for 10 years. And now the goal has been achieved. Philae landed on the comet surface. We clearly saw it on the testimony of telemetry”, – reported in the ESA.

“Philae is talking to us. It comes from all the new data that we process right now. Continue reading
