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

Planet in February 2016

In February, continuing a run of parade of the five planets – mercury, Venus, Saturn, Mars and Jupiter lined up in the morning sky. In early February, their background will be the sickle of the waning moon, and by the middle of month two of the five planets will become unavailable for visual observations of mercury and Venus, disappearing into the rays of the rising Sun. Jupiter is in its best appearances in 2016. Uranus and Neptune gradually complete its visibility in the evening sky. The sun moves through the constellation of Capricorn, February 15, passing in the constellation of Aquarius.

The moon will come together with these planets: 1 February when the lunar phase is from 0.5 to Mars, on 4 February when the lunar phase 0.2 to Saturn, on 6 February when the lunar phase is 0.08 – Venus and mercury, 10 February when the lunar phase 0,03 – with Neptune, on 13 February when the lunar phase 0.25 and with Uranus, on 24 February when the lunar phase 0,97 – with Jupiter. For observations it is better to choose nights when the Moon is near the full phase passes close to the observed planet. Continue reading

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
