Brown and Batygin told about the discovery of the ninth planet of the Solar system

Scientists shared their impressions

21 January 2016, two scientists from the California Institute of technology, Professor Mike brown and Professor Konstantin Batygin has officially announced that they have found a ninth planet in our Solar system. According to their mathematical models, it is a gas giant like Uranus or Neptune, the mass of the discovered planet 10 times the mass of Earth, it rotates in an orbit 20 times larger than the earth and it requires from 10,000 to 20,000 years to make one complete revolution around the Sun. However, very reliable model of scientists has demonstrated and existing telescopes have not yet managed to see her.

Scientists have been very mixed on the nature of their activities and perhaps that is why they have achieved such amazing results. So brown has increasingly resorted to methods of observation and explores distant objects in our Solar system, whereas Batygin relies more on the laws of physics and mathematical calculations. Apparently, that tandem allowed the researchers to calculate the so-called ninth planet. Continue reading

The region of formation of comet Tempel 1 and the model of solar system formation

“Our observation was aimed at studying the chemical composition of the comet Tempel 1,” says Michael Mumma (Michael Turner) from space flight Center NASA Goddard (NASA Goddard Space Flight Center). The Mumma and his colleagues used a powerful telescope, the Keck Observatory in Hawaii for a detailed analysis of the light emitted by the gas of the comet at the moment of impact. Since each type of atoms and molecules has its own characteristic frequency of radiation, on the basis of this, scientists were able to determine the chemical composition of the comet’s nucleus.

Comets are blocks, which consist of ice and dust that move in elongated orbits. It is believed that the nucleus of the comet is gas and dust formations, remaining after the formation of the main bodies of the solar system.

When approaching the Sun, its radiation heats the comet’s nucleus, releasing dust and gas. The latter form a coma (cloud around the nucleus) and one or more tails. Repeated heating leads to the fact that disappear from the surface of the substance having a low boiling point. In fact, the nucleus of a comet is formed “crust” that is different chemically from its internal regions. This makes it difficult to determine the true composition of the comet just by studying the gas in its tail. Continue reading

The most important mysteries of the solar system

The earth is the home of humankind. Can be considered and the Solar system. After all, we already went to the moon, our spacecraft has reached other planets. It would seem that about the area of Land we need to know everything.

Actually mankind for decades trying to unravel such close and such mysterious phenomena. Describe below of the top ten mysteries of the Solar system.

The Oort Cloud. The main issue regarding this site is that whether there is any? This is perhaps the chief mystery of our Solar system. Scientists have suggested the existence of clouds only hypothetically, but this piece of the Universe no one has seen. The theories then formed comets with long orbital period. Scientists can only assume that the Oort cloud is at a distance of 50-100 thousand.e. from the Sun. The bounds of this object lying on the very edge of the Solar system. The billions of bodies are from the cloud is bound by gravity to the Sun. Continue reading

The largest planet

Astronomical parameters

The largest planet of the Solar System, the third brightest object night sky (after the moon and Venus). Is gazaille body, hard surface does not. Consists mostly of hydrogen and helium. Due to their size can be observed with the naked eye as a star of the first magnitude, but only for a short time in the morning or in the evening. The average distance from the Sun 778 million km conversion – 314.8 years 11 days.

Jupiter has 16 satellites: IO, Leda, Teba(Phoebe), Carme, ELARA, Ananke, Europe, Metis, Pasiphae, Sinope, hamalia, Ganymede, Lysithea, Amalthea, Callisto, and Andrastea. System his companions like a scaled-down model of the Solar system. The four major satellites (Ganymede, Callisto, IO and Europa) discovered by Galileo and are called the Galilean. Continue reading

Cosmonaut held in Tula space debate

On cosmonautics Day, the students gathered in the TSU to discuss the most interesting “star” questions.

On the agenda of these debates were three interesting topics: “Space tourism” “Space debris” and “give a star from the sky”. All the “pros” and “cons” emotionally discussed two teams from the main universities: the University and the Tomsk state pedagogical University.

Leading the debate was inhabitant of Tula Sergey Zaletin, pilot-cosmonaut and hero of Russia. At the beginning of the meeting, he noted that the conquest of space means a lot to the Tula region:

Of the 85 regions of our country was only 120 astronauts and four of them – from the Tula region: Yevgeny Khrunov, Valery Polyakov, Nikolai Tikhonov and me. Tikhonov is the youngest of us, and in flight he is only going two years later.

I noticed an interesting pattern: Polyakov 71 years old, I’m 51, 31 Tikhonov, probably, somewhere on the Tula earth future astronaut growing up, by my calculations, he should now be 11 years old. Continue reading
