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

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 spaceships of our ancestors

Vitmaras called intergalactic ship (“Big sky Chariot”), able to endure “in her womb” to 144 spacecraft Wightman type.

The Wightman is a spacecraft (“Small Heavenly Chariot”), fit for travel directly between the Lands of different solar (stellar) systems and landing on them.

Remember that our ancestors called the Great Vitmara “Heavenly Chariot.” Such spaceships were intended for very long flights, for travel from one Galaxy to another. These space ships could carry, as mentioned earlier, at least 144 Wightman. The Zionism was used as a research spacecraft and to move between neighboring star systems that have been deleted on a relatively “small” distance, and also shopping.

There were two types of space ships — INTERGALACTIC — CLASS BIG VITMARA and GALACTIC CLASS — ZIONISM. Class of galactic space ships (Wightman) was used for travel within one Galaxy between the nearest star systems. Class of intergalactic space ships (Vaitmar) — to move between near and far Galaxies and nutrigenetic over long distances. Continue reading
