Scientists named the cause of the cosmic light night Chelyabinsk - TVNZ

After the fall of the meteorite

residents of the Southern Urals were wary to take everything that comes from the sky. Last weekend, the night sky began to literally glow ! Someone admired this phenomenon, and some it is not a little alarmed. On the Internet you can find a video made by a resident Miassa. A man takes a luminous sky and subdued voice says:

– What is it, no one knows, and what will happen next – is unknown.

Fortunately, the apocalypse did not happen. But the people of the region more than a day wondering what it was. The most popular version – aurora, though scientists insist on the fact that we have seen so-called noctilucent clouds. they are formed at a great height is greater than 80 kilometers, consists of microscopic particles of ice, volcanic or cosmic dust. And the light of what they fall sunlight while not under ground night.

– Most signs points to the fact that it was the noctilucent clouds – says astrophysicist at CSU Sergei Zamozdra. – First of all, the picture is static. The aurora should be poured to change the color and shape. And we saw a silvery glow and it was moving. Second, the shape was characteristic of mesospheric clouds, a kind of jet. Finally, now is the time for such a phenomenon, the end of June, when short night. This phenomenon is not unique, but rather rare. Too many factors must come together to put together, to see such a cloud. NASA has a special satellite, which studies noctilucent clouds. As it can be judged on the processes and changes in the upper atmosphere.

By the way, according to the scientist, it is realistic to see the Southern Urals and the northern lights. This can happen in the case of a powerful solar flare. Then the lighting effects in the atmosphere would be visible to us. But this happens very rarely. On the eve of the Chelyabinsk glow sun was not active.

– We read a discussion of this phenomenon in social networks and felt that young people have a gap in education is associated with the fact that abolished the study of astronomy – he says – it is clear that the lack of basic knowledge about the world. The same thing we see when there are photos from the halo phenomenon, when, due to the refraction of light in the sky there are two Sun. People take it for something incredible phenomenon. Soviet schoolboy of noctilucent clouds or halos would not have brought down confused.
