Stars turnover – speed of stars rotation
Stars turnover – speed of stars rotation – The Sun rotates at the equator at a speed of 2 km / s.
Astronomers have discovered that the star of the Tarantula Nebula – VFTS102,
rotates at a record speed of 600 km/s.
Meteorological week analysis
Meteorological week analysis – After analyzing the meteorological data from the years 1991-2005,
the German researchers found that the hottest day of the week is Wednesday, and the driest – Monday.
However, in the weekend usually it rains. Within a week, smog obscures the sun and the exhaust gases
are involved in the formation of clouds. On Saturday, this phenomenon goes critical.

The calculations made by Thales of Miletus, a Greek philosopher, mathematician and astronomer. The creator of the foundations of science and European philosophy. He created the first rational theory of nature.
Nicolaus Copernicus – heliocentric vision of universe
Nicolaus Copernicus (1473 – 24.05.1543) – heliocentric vision of universe – Astronomer, mathematician, lawyer and economist. He discovered the variability of the eccentric motion of the Earth and solar zenith with respect to the fixed stars. In his work “On the Revolutions of the Heavenly Spheres“ he described the heliocentric vision of the universe. He published a treatise monetary.
Solar wind – The Sun has an impact on the processes
Solar wind – The Sun has an impact on the processes in the solar system in many different ways. Although gravity is maintained thanks to its system time emits a space wide range of molecular types of radiation, to which the feature ” wind of the Sun”. Researchers from the University of Leicester have combined the data. Obtained during the observations of solar activity from data obtained during observations of the Martian atmosphere, provided by satellites. The solar corona disappears from the environment until 2.5 x more particles. Observations were conducted during the fall of solar activity within the 11 – year solar cycle.
Largest observed star – Betelgeuze
Largest observed star – The changing their dimensions star Betelgeuze in the constellation Orion (the maximum volume of a diameter of 980 million km) is 17 thousand. times brighter than the Sun.
Incredible galaxy – Lenticular galaxy NGC 1277 in 14% consists of a black hole, usually they represent 0.1% of the mass of the galaxy. Located in the center of a monster with a mass of 17 billion times that of the Sun is probably the most powerful ever discovered. NGC 1277 is at the same time 10 times smaller than our Milky Way.
When Sun goes out
When Sun goes out – If we average all astrophysical estimates, the sun goes out for 4 billion 430 million 800 thousands years. But not happen in one day, it will be a very long process of increasing volume, expiration and slow death.
Phenomena on Uranus
Phenomena on Uranus – The axis of the planet lies almost in a plane in which the planet revolves around the Sun. Uranus is the coldest planet of the Solar System (-220 ° C in the atmosphere).
Whales beware of sun!
Whales beware of sun! – Whale skin is just as sensitive to sunlight as humans. Researchers from Newcastle University and the Mexican and Canadian marine biologists drew attention to the blisters of these sea animals. In most cases, they were not infected, which means that the cause must be sought elsewhere – UV. Due to the fact that the blue whales are light skin tone, immediately appear on the changes caused by UV radiation – to increase the amount of pigment and mitochondrial DNA damage. Sperm whales spend for more time on the water surface, which also will not miss the effects of sunlight, even though their skin is much darker.
