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

For the non-refundable flight to Mars 52 Russians are selected

Dutch company Mars One intends to send the first volunteers to the Red planet by 2023. But our expert explains why it’s not going to happen

Organizers of large-scale colonization of the red planet have previously determined the volunteers who will fly to Mars by 2023

Organizers of large-scale colonization of the red planet have previously determined the volunteers who will fly to Mars by 2023. Dutch company Mars One is counting on that date for $ 6 billion to build a permanent base there.

Just primary have been selected 1058 candidates. Most of them are residents of the U.S. — 297 people. From Russia – 52 volunteers. But by 2015 the project managers will select 24 people who will go to Mars. By the way, the company warns that a return ticket is not provided.

Open planet in honour of Day of Astronautics

One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.

Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.
