A giant meteor once crossing the night sky recovered from the bottom of the lake.
Scientists on Wednesday recovered what could be the largest part of this meteor from Chebarkul Lake outside the city.
A giant chunk of the Chelyabinsk meteor weighed 570 kilograms or 1,256 pounds before it broke, believed to be the largest recorded meteor strike in more than a century according to report.
More than 1,600 people were injured by the shock wave from the explosion, estimated to be as strong as 20 Hiroshima atomic bombs, as it landed near the city of Chelyabinsk. It took salvage crews 10 days just to uncover it from the mud it was buried under on the bottom of the lake.Video Credit: RT Russia Today
The night sky and studies of it have a historical place in both ancient and modern cultures. In the past, for instance, farmers have used the state of the night sky as a calendar to determine when to plant crops. Many cultures have drawn constellations between stars in the sky, using them in association with legends and mythology about their deities.
The anciently developed belief of astrology is generally based on the belief that relationships between heavenly bodies influence or convey information about events on Earth. The scientific study of the night sky and bodies observed within it, meanwhile, takes place in the science of astronomy.
The visibility of celestial objects in the night sky is affected by light pollution. The presence of the Moon in the night sky has historically hindered astronomical observation by increasing the amount of ambient lighting. With the advent of artificial light sources, however, light pollution has been a growing problem for viewing the night sky.
Special filters and modifications to light fixtures can help to alleviate this problem, but for the best seeing both professional and amateur optical astronomers seek viewing sites located far from major urban areas.
