verenkiertovaäjan

Verenkiertovaäjan, also known as the "blood moon" or "lunar eclipse," is a celestial event that occurs when the Earth comes between the Sun and the Moon, casting a shadow on the lunar surface. This phenomenon can only happen during a full moon when the Sun, Earth, and Moon are aligned in a straight line. The term "verenkiertovaäjan" is derived from the Dutch words "veren" meaning blood, and "kiertovaäjan" meaning lunar cycle.

During a verenkiertovaäjan, the Moon does not disappear from view but instead turns a reddish or coppery color, hence the name "blood moon." This coloration is due to a process called Rayleigh scattering, where the Earth's atmosphere scatters the blue and green light from the Sun, allowing the red light to reach the Moon. The exact shade of red can vary depending on the amount of dust and clouds in the Earth's atmosphere.

Verenkiertovaäjan is a relatively rare event, occurring about 2-4 times a year. It can last for several hours, with the total eclipse phase lasting up to 100 minutes. The event is visible from anywhere on the night side of the Earth, provided the weather conditions are clear. It is a popular subject for astronomers and stargazers, offering a unique opportunity to observe the dynamics of the Earth-Moon-Sun system.
