You tell, which of these pictures will win NASA's game...A land bent by the wind or a trap of ice on water?
Our earth looks very beautiful when seen from space. Somewhere the mountains, somewhere the water and sometimes the winds themselves make such shapes that the onlookers are compelled to prevent there heart. it's very difficult to choose on one amongst these amazing natural scenes, but the planet Observatory of the US space agency NASA started a singular competition for it a month ago. Starting with 32 pictures, now only two are left within the final, out of which only 1 are going to be the winner. NASA started a contest for pictures taken from the Landsat satellite. within the final two pictures, one is of the Mississippi Delta and the other of the icy waters along the coast of the Arctic Ocean near Russia.
Here the winds have changed the form of the bottom ponds and wetlands with time and therefore the shape that has start up after being carved is extremely attractive. Seeing them, it seems as if blue veins are starting off. About 4 years ago, a paper published in Geophysical Research Letters showed that because of the effect of wind, water waves changed the banks of the ponds and that they turned within the direction of the wind. Their impact was seen on 3 watersheds near the Mississippi. For this, researchers analyzed 10,000 satellite images between 1982 and 2016. the image which is now within the field to win was taken within the year 2016 and it shows the Atchafalaya Delta.
The second picture is of a net made from ice and water on the Arctic coast in Russia. it's sort of a thick spider web. The islands spread from the mainland of Siberia to the north are cover 30 thousand square kilometers. The New Siberian Islands are divided by the Sannikov Strait. It connects the sea to the west and the East Siberian Sea to the east. it's covered with snow for many of the year. The photographs taken by Landsat 8 show frozen sea water. because of the wind and the flow of water, the ice cracks and also the water starts to seem black in color. because of the impact within the thickness of the ice, different colors are visible, which are gray and blue somewhere.
