    There are many strange things in the sky that can make it glow in unbelievably beautiful colours, but it is extremely rare to see two completely different natural phenomena at the same time.

    NASA astronauts from the International Space Station (ISS) have managed to capture two atmospheric phenomena – aurora borealis (or northern lights) and airglow (or skyglow), in one photo.

    The photo, which was shared on Instagram, was taken by the astronauts in March, while the ISS was moving over Alaska. The footage features two bright lines of light, occurring simultaneously at the same heights, but due to different reactions, as they are not linked to each other.
