NASA 'deadlock' decodes the mysterious light in space

There is a light on Earth that can only be seen in space, where does it come from? To explain this, the US Aeronautics and Space Administration (NASA) conducted a year-long study. However, up to now, no exact answer has been found.

NASA said that from June 2015 to June 2016, the space-observing climate satellite (DSCOVR） of the US National and Oceanic Administration has captured 866 light beams in space at the location millions of kilometers from Earth.

A strong light flow, only visible in space.However, where it comes from, it is still a mystery.

Initially, the researchers assumed that it could be sunlight reflected by water. However, the beam is too large to reflect from lakes or other water bodies.

Later, the researchers concluded that these beams of light came from ice crystals in an atmosphere of five to eight kilometers high reflecting sunlight. The researchers used a multispectral camera (EPIC) and found magic clouds in this high altitude atmosphere.

Therefore, Alexander Marshak, a scientist at NASA Goddard Space Center's satellite project, said: "The reflected light source is definitely not from the ground. It is definitely from the ice, and very it may be reflected horizontally from ice crystals ".

Recently this study has been published in the 'Physical Earth Research Report'. However, researchers still cannot explain why only the light of ice converges in such a highly concentrated atmosphere that it can be observed in space.

Scientists use equipment to capture light.

Secret beam of light visible in the air floor.

In fact, in early 1993, the famous astronomer Carl Sagan recognized this. At that time, Sagan and other scientists discussed in "Nature" magazine, light reflected from the sea area.

But then the scientists confirmed that Sagan and the others were wrong, and the magic of the light source actually came from the land rather than from the sea.

For more than two decades now, the origin of this reflective light is still a mystery.
