Earth’s atmosphere shines in space station photo


NASA released a new image captured from the International Space Station (ISS) that reveals the glow generated by the Earth’s atmosphere. The registration was made on March 4th, when the ISS was positioned over Kazakhstan.

This phenomenon is called airglow or, in the Portuguese translation, Atmospheric Luminescence. According to scientists, this occurs when oxygen and nitrogen molecules come into contact with the ultraviolet light emitted by the Sun.

With this, a coppery luminous band appears that outlines the planet from a short distance. In the record made by NASA it is possible to identify this band easily, in addition to some stars in the background. Check out the image below:

At the time the light strip was captured, the Space Station was 241 km high. During the phenomenon, gases from the Earth’s atmosphere that were present in the region were energized by solar radiation, which generated the light band.

The ISS has already been used to record other moments in space similar to this, like a kind of polar dawn. What did you think of this phenomenon? Give your opinion in the comments!
