It is now solved a question of principle: who will be the host space for the next two decades. Half a century, when humanity is poked in the Earth’s vicinity, still not fully understanding why (except that to get ahead of a competitor), has ended. And money in space dumped a lot. The project “Apollo” with six successful expeditions to the moon cost the us Treasury $ 25 billion (in prices of the 70-ies of XX century). And each launch of the Shuttle – under $ 500 million.
The Soviet Union was worth 2.5 billion rubles was never carried out lunar program (and it is in those years when a good wage was considered to be 90 rubles per month). More than 16 billion rubles were thrown into the system “Energy – Buran” Soviet Shuttle flew only once.
Yeah, from the projects was giving. All of these filters, Velcro and scanners, developed for the space and will be useful on Earth… But now we are talking about strategy.
ISS – the day before yesterday
The same strategy that the space powers (Russia and the USA joined China. India. Japan and the EU ) now consider the money very well and meticulously thought through perspectives. Continue reading

According to the data sent to earth orbiting space telescope GALEX, astronomers have made the image of the Veil nebula in the ultraviolet range. The Veil nebula (W78, Sharpless 103), which is also known as the Loop nebula or nebula Fishing net, is a diffuse nebula in the constellation of Cygnus. Was opened on 5 September 1784 by astronomer William Herschel. Previously, astronomers believed that this huge and relatively faint supernova remnant that exploded about 5,000 to 8,000 years ago, is at a distance of about 2500 light years from Earth, however, studies that fulfilled the space telescope “Hubble”, showed that the nebula is much closer – at a distance of 1470 light years. However, it extends for a distance of about 90 light-years, taking in the sky region of 3 degrees. Astronomers have smashed the nebula into four parts: separation – nebula “witch’s broom” (NGC 6960). South-West side of the Pickering’s Triangle (NGC 6979), East side (NGC 6992), which represents the fibrous structure of the nebula and the North side (NGC 6995).
Astronomers have discovered in the nearby galaxy M95 supernova. The discovery was made on March 16, 2014, when astronomers, both professionals and Amateurs, noted a bright spot on the outskirts of a spiral galaxy with a jumper M95 (NGC 3351), which is at a distance of 38 million light-years away in the constellation of Leo.

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
