A rare phenomenon that took place on November 19 caused the Moon to transform in the excitement of astronomy lovers around the world.
The full moon on November 19 turned red when it was almost completely covered by the Earth’s shadow during a partial lunar eclipse. This is the longest partial lunar eclipse of the century, and also the longest in 580 years, according to the Holcomb Observatory in Indiana, USA. The total duration of the lunar eclipse is nearly 3 hours and 30 minutes.
During a lunar eclipse, the Moon turns a dramatic red color. The “culprit” is the Earth’s atmosphere. The Earth blocks most of the Sun’s rays reaching the Moon, but some still bypass the Earth, pass through the atmosphere and reach this natural satellite. The atmosphere filters out wavelengths shorter than blue and allows only red and orange wavelengths to pass through.
