“The orange glow of the setting sun covers Earth at the bottom of the image. The red haze of an aurora is just above Earth's atmosphere. At the top of the image are two solar panels, and “a small solar panel appears. Bottom left. In the background, the darkness of space is filled with dots of bright stars.” NASA About the film.

The photo is one of many images taken by astronauts from the ISS crew from 420 kilometers away, where the International Cooperation Observatory is located, orbiting Earth at a speed of 27,000 kilometers per hour about 16 times a day.

Explained by NASA, the orange of the sunset is due to the fact that as the sun moves lower in the sky, its light passes through many parts of the atmosphere until it reaches the earth. As a result, blue light is scattered more, meaning red and yellow light passes through directly and can be captured by our eyes.

At some sunsets, the sky appears red because tiny dust particles, pollution, and aerosols in the air scatter blue light and allow red and yellow colors to pass through the atmosphere.

Are sunsets the same on all planets?

Of course not. The color of the sunset depends on the composition of each planet's atmosphere. For example, the atmosphere Marte It is very fine, composed mainly of carbon dioxide and containing very fine dust particles. These microscopic particles scatter light differently than gases and particles in Earth's atmosphere.

Through photographs taken by rovers NASA contained MarteYou can see the sunset Marte It has a completely different color than the color Tierra.
