Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.

Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.

The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:


Ice (water, ammonia, methane, carbon dioxide)

Some organic materials (e.g., resin)

Rocky ground (optional) Continue reading

Around the Solar system

Top 5 for the day

Automatic interplanetary scouts NASA, the European space Agency and others currently collecting information about our Solar system. Right now the spacecraft are in orbits of Sun, mercury, Venus, Earth, Mars, and Saturn, flying to other small space objects.

Thanks to the astronauts and to all automatic mechanical scouts in space, we have the opportunity to see “family” Photos of our Solar system.

Recover in the journey.

For a start look at our Earth. It looks like Moscow, when the ISS passes over the territory of Ukraine, February 2, 2015. Scientific evidence indicates that Earth formed from the solar nebula about of 4.54 billion years ago. Presumably life appeared on Earth about 3.9 billion years ago, i.e. during the first billion after its occurrence.

So it looks from space, the Salt flat of Uyuni — dried salt lake in the South of the desert plain Altiplano, Bolivia at an altitude of about 3 650 m above sea level. The inner part is covered with a layer of salt thickness 2-8 m During the rainy season salt marsh covered with a thin layer of water and turns into the world’s largest mirror surface.

Future technology

Space tourists have already bought vouchers from Roscosmos for millions of dollars, which means that interplanetary travel ceased to be only a figment of the imagination of science fiction writers. Mankind has realized at last that the earth’s resources ischerpaemy, and set his sights on the conquest of the territories on a much larger scale and very different properties. There will be dozens or hundreds of years, and prepapre…our great grandchildren, perhaps when meeting have to introduce myself, “Hey, Hey, I’m from Earth. We got such a strong gravitational field, and there’s somehow easier to breathe”.

Interesting development in this area is the space Elevator, which will allow you to run in a cargo space without using rocket equipment. For the first time this thought Konstantin Tsiolkovsky, and in the twenty-first century NASA is already funding the development of this project. In the future it will be cheaper than building the missiles the media.

In fact, it must be a cable anchored to the Earth’s surface on a moving vessel at one end and the other adjacent to the space station, fixed stationary relatively to the planet. Continue reading
