All of us know that our atmosphere is fast changing and humans are the only beings responsible for that. Till now Earth was not giving us any visual signs of the damage caused to its atmosphere.
But now a new NASA satellite has recorded the first detailed images from space of a mysterious type of cloud known as “night-shining” or “noctilucent” clouds. Till now these bright lights were seen only in the polar regions, however, now these clouds are on the move and are brightening several other parts of the northern hemisphere.
Atmospheric scientists have stated that it is clear that these clouds are changing, which might be a sign that the atmosphere is changing. However, they are not too sure about the possible causes of these changes. Till now all they know is that there is some connection between the clouds and the changes in the lower atmosphere. This could also be a potential warning that our Earth environment is being changed.
The satellite named Aeronomy of Ice in the Mesosphere imaged these clouds on May 25. People on the ground began seeing them on June 6 over Northern Europe.
The clouds are formed some 50 miles above the surface of Earth, in the layer of atmosphere known as Mesosphere. AIM will now record two complete cycles of these clouds so that researchers can figure out why these clouds are being formed and how they might be related to the global climate change.
