American astrophysicists for the first time in history, have received experimental electric heater for car confirmation hypothesis that a large part of the universe occupied by the so-called dark matter that does not emit and do not reflect enough light to be visible. Observing the collision of two galaxy clusters, it was found that most of the ordinary matter in the two galaxies, which occurs in hot gases or plasma electric heater for car form during the collision electric heater for car friction forces began to move more slowly and actually electric heater for car underperformed their galaxies. Thus, the ordinary matter turned out to be separated from the dark matter. In order to follow these cataclysms were mobilized world's most powerful telescopes - Hubble Space Telescope, Chandra X-ray Observatory, which is owned by NASA, the European Southern Observatory's Very Large Telescope (VLT) and the Magellan optical telescopes. The hypothesis of the existence of dark matter, astronomers have already put 20th century, 30th years when it was discovered that the galaxy rotation is much faster than in theory it should be, given the mass of the galaxy. Currently, it is believed that only 5% of the universe consists of ordinary matter, about 25% covered by dark matter, while a further 70% - the so-called dark energy.
If you carefully observe the moon at different times, it can be noticed that it is always seen in the same light and dark regions of distribution. electric heater for car Moon to Earth is always pointing the same side. As the result of this movement? After the emergence of the rotation of the Moon was clearly not related, ie, the rotation period electric heater for car was shorter than the orbital period. Due to gravity acting on the uneven Moon's crust, the crust and the liquid core causes friction, which for so long hindered rotation, and finally the rotation and orbital periods was the same. Phase out one propelling the Earth 27.32 days. During this time, the Moon and a turn around an axis, so the Earth is always facing the same half of the month.
Is not easy to determine the age of the Sun. One possibility is to study meteorites. These objects which fell down on the earth is from the same time as the Sun and the planets, so their age is close to the solar age. Age is determined by radioactive nuclei by similarity. As a result, the sun set at the approximate age of 4.5 billion years. Another method of age determination is based on the same solar physics. Today, scientists are able to reconstruct the computers in our solar development in the wild state. This led to the conclusion that the sun is shining from about 4.6 billion years. Thus, these results are almost consistent with the results of the determination of the age of meteorites.
Visible light as well as infrared and ultraviolet telescopes used for reception. The telescope is a device that collects and detects electromagnetic radiation towards the sky. Many telescopes form images of celestial bodies. lr the telescopes electric heater for car that captures not radiation but particle flow from space. electric heater for car There are three main types of telescopes: the lens telescope or refractor, reflector electric heater for car or spoguļteleskops and mixed-use telescope or katadioptriskais and consists of mirrors and lenses. The world's largest telescopes are spoguļteleskopi. Through the increased aperture telescope, astronomers can see the celestial objects with low radiation. The invention of the telescope and its further development has made a major contribution to the creation of our world view.
Stars arises when the general molecular cloud becomes unstable and the gravity collapses. Cloud center electric heater for car of gravity for the release more heat, until finally the temperature and density of the molecular cloud center is so high that the reaction can occur in which the hydrogen turns into helium, which is characterized by the stars. Reaction caused by energy stabilizes the star collapse ends, and the star of your radiation repels itself from the remaining material until it begins to shine in full splendor. Of residual material can form another star or a planet around a young star.
All the planets except Mercury and Venus have months. Month compared with the mass of the planet mass of our Earth and Moon system is different electric heater for car from the others. Earth's mass is only 81 times larger than the Moon mass, while the other planets and their largest monthly mass ratio of 10, 000 and more. As was to be so high the moon? Today, astronomers believe electric heater for car that the early phase of our solar system are about 4.5 billion years the Earth has collided new one celestial body the size of Mars and pulled electric heater for car from it a part of which later caused the moon.
By putting a lot of stars, astronomers discovered regularities linking the main characteristics of the star. According to Hercšprunga-Russell diagram consists of a number of stars in the clear distinction between electric heater for car groups. Located on the top of the charts pārmilzu stars beneath electric heater for car them - giant stars. Hercšprunga-Russell diagram from left to right, crossing electric heater for car the curved bar that includes a stellar cast. They are main sequence stars. They have a different mass, luminosity and temperature, but all the main source of energy is kodolterm
