The blood moon on September 7: A fascinating sky activity!

On September 7, a fascinating astronomical event in the night sky will be visible: a "blood moon" that appears during a total lunar eclipse. The moon is completely covered by the core shadow of the earth, but does not disappear. Instead, he will shine in a reddish color, which makes the phenomenon particularly remarkable. Loud OE24 this color leads to the scatter of light in the earth's atmosphere. Uwe Pilz from the Association of Sternfreunde (VDS) explains the phenomenon of Rayleigh scattering, which is responsible for the fact that the moon appears red as it moves through the shadow of the earth.

With a lunar eclipse, the sunlight filters out the short -wave blue light shares, while the long -wave red light shares that are spread more reach the moon. As a result, the earth's atmosphere as a bright ring around the moon becomes visible. The intensity of the red tone can even allow conclusions to be drawn about the state of the atmosphere. A deep red moon can indicate a high particle density in the air.

The scientific background

The rayleigh scattering is a physical phenomenon that occurs on small particles when the elastic spread of electromagnetic waves. This scatter is responsible for the most varied colors that we perceive in the sky. Blue light is sprinkled more than red, which makes the daily sky appear blue. In contrast, the longer route, which draws the light back through the atmosphere at a low position, leads to the fact that the moon or the sun appear reddish Wikipedia explained.

When the moon is deep on the horizon, the light has a longer way through the atmosphere, which leads to strengthening the scatter. But not only the moon becomes reddish during a total lunar eclipse-the sunsets also become more intense and colorful, which in turn is influenced by the Rayleigh scattering. A high particle density, such as by volcanic dust or Saharasand, can additionally reinforce the color intensity of that sky phenomena.

Eyewitnesses and photo options

The phenomenon of the blood moon not only offers scientific explanations, but also a wonderful opportunity for hobby astronomers and photographers. How Mirror reports, many invite you to find the best places to observe the blood moon and to capture the best recordings for an unforgettable moment.

In summary, the blood moon on September 7 will offer an impressive spectacle in the night sky, which can be explained by interesting physical phenomena such as the Rayleigh scattering. This event is a wonderful occasion to experience the fascination of astronomy and maybe even take some impressive photos.
