What is a lunar eclipse? How does it occur?

Category: Science

Answer:

A lunar eclipse is a phenomenon that occurs when the moon travels behind the earth and blocks the rays of sunlight thus covering the lunar surface in shadow. The shadow of the earth, which is seen on the moon, is made up of two parts, the outer or penumbral shadow and the inner or umbral shadow. During an average total lunar eclipse, the moon will cross the umbra in about one hour’s time. This phase is called totality. During this time, the moon will appear to have a reddish hue due to sunlight bending around the edge of Earth.
