Comets of the centuries

In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a “Great comet” − a rare visitor, perhaps the brightest comet of the twenty-first century.

Alas, severely battered during the close approach to the Sun in November of this year, ISON no longer promises such a bright future. To the naked eye from the Ground to see it would be impossible − but hopes not worth it to lose. Somewhere in the dark depths of space, probably unnoticed by anyone else is racing the comet, which will deserve the attention and present us with an unforgettable sight. This has always been the Large comets appear about once a decade, and every century one of them was especially bright.

Comet ISON

We will tell you about these “comets of the century”, since the sixteenth century. It is interesting that they flew as a rule, in the second half of your century, and has had an average of once every 97 years. Given this, we can calculate that if the comet of Ikeya-Seki (C/1965 S1) visited the Earth in 1965, following a visitor, you can wait until 2029.

However, to predict what particular impossible: a Big comet can appear quite unexpectedly, at almost any time. The message we may hear tomorrow.

The order of the planets

Not so long ago such a statement would cause an uproar in any self-respecting astrophysicist and most likely, it ended in the usual enumeration of the several variants of the origin of our Solar system. Today, however, a number of researchers not only did not reject this version and think its main. What is the reason? We will try to understand.

It all started with sightings NASA space Observatory named “Kepler”. The satellite was launched in 2009, and in 2020 due to the loss of orientation in space failed. The Observatory was equipped with incredibly sensitive Photometer and specially designed to search for exoplanets, i.e. planets outside our Solar system like Earth. The ability of the apparatus to observe more than 100,000 stars at the same time very quickly gave the opportunity for scientists to get incredible data about other Solar systems.

In early 2010 the Observatory was discovered planetary system Kepler-33. The star Kepler-33, located in the constellation of Cygnus, was bigger than our Sun, and planets revolving around it, was very close to the parent star. Continue reading

The origin of the solar system

The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .

Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.

Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.

The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available. Continue reading
