Solar system. Planets of the solar system

Its center is a huge star called the Sun. It is the closest star that is billions of years gives us light and heat. Without it, impossible would be life on the planet. Around it revolve the planets, of which eight are known today, as well as other celestial objects.

Schematically, the structure of the solar system is as follows:

Man is always interested in the question thus arose our solar system. But it was a long time before scientists were able to answer this question. There were many versions and assumptions on this issue. And today, astronomers are continuing their investigation.

According to a hypothesis of Kant-Laplace five billion years ago there was only a gas cloud. It moved through the universe, but at some point he undergoes certain processes. Then there is compression and then begins the rotation, the center of rotation is the fastest. The temperature at the center of the cloud began to grow and formed a protostar that later became the Sun. The nebula continued to spin, and the star are unable to absorb all the substance of the nebula, they are attracted, experienced, forming planetesimal. One of them appeared on the planet.

First test flight of the balloon

Company World View Enterprises located in the U.S. state of Arizona, announced the successful completion of the first small-scale test flight of a balloon, equipped with a special capsule that is being developed for space tourists could “float” on a 32-km altitude above the Earth’s surface.

Last Tuesday, 24 June 2014, the company World View Enterprises in Tucson, said reduced-scale copy of the balloon was launched last week from Roswell (new Mexico). According to the President of the company Jane Poynter, developed the balloon broke the world record, as in the stratosphere was raised payload, the mass of which is 1/10 by weight of the intended load full-scale model of the balloon.

Jane Poynter could not hide his joy at the results of the test flight, preparation and conduct of which until yesterday was kept a closely guarded secret.

For the test flight balloon was used, similar to that which the Austrian Felix Baumgartner was used to set a world record, which consisted of lifting to a height of 32 km above the Earth’s surface. Continue reading

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.
