Green Flash sunset is a rare phenomenon and the chance to see it is a source of pride for every viewer.
What do we see in today’s NASA image?
In the past, it was thought that glowing green is a myth, but now we know that this phenomenon occurs when the Earth’s atmosphere acts like a prism and a lens. The light that shines from the upper part of the sun into the earth’s atmosphere is refracted at different heights by the layers of the atmosphere and its colors are broken down. As a result, the Earth’s atmosphere magnifies the two reflected images created and a thin green layer appears just before the sun disappears.
This sunset image, captured last April from the Cerro Tololo Inter-American Observatory in Chile, is more unusual than ever. Many thermal layers of the atmosphere created several false images of the sun, and as a result, several green glows appeared at the same time. Just seconds after two astrophotographers captured this multi-layered glow, the sun set behind the clouds.
