Red Moon color image

Quick answer：

The 'Red Moon' phenomenon, also known as a blood moon, refers to a total lunar eclipse where the Earth's shadow causes the moon to appear red. It is a natural optical phenomenon that occurs when the moon passes through Earth's shadow. Images of the Red Moon can capture the stunning red hues and are often used to illustrate this celestial event. Lunar eclipses occur when the Earth comes between the sun and the moon, casting its shadow on the moon.
