Glossary term: 월식
Description: 월식은 달이 지구의 그림자 속으로 지나갈 때 일어나는 현상입니다. 태양, 지구, 달이 일직선으로 정렬되어, 지구가 태양과 달 사이에 놓일 때만 일어날 수 있습니다. 따라서 월식은 보름달이 뜨는 밤에만 일어날 수 있습니다. 달이 지구의 그림자 속에 완전히 들어가면 개기월식, 일부만 가려지면 부분월식이 됩니다. 월식의 모양과 지속 시간은 달이 월식이 일어나는 순간 지구 주위를 도는 궤도에서 어디에 있는지에 따라 달라집니다.

The Eclipse Between Us, by Muhammad Rayhan, Indonesia

Total lunar eclipses belong to the rather spectacular celestial events and can be observed easily with and without a telescope. Here we see the stages of the total lunar eclipse of 31.1.2018 photographed in Indonesia: starting with the entry of the full moon disk into Earth's round umbra, the totality as Blood Moon, and the beginning of the Moon's exit from Earth's umbra until moonset.

The eclipsed Moon sets near the Rochetta di Prendera, Dolomiti Unesco, by Alessandra Masi, Italy
Caption: First place in the 2021 IAU OAE Astrophotography Contest, category Total lunar eclipse.
A lunar eclipse occurs when the full moon moves into the Earth`s shadow. This is the case when the Sun, Earth and Moon are exactly or very closely aligned. The reddish light reflected from the lunar surface is caused by sunlight that has been refracted on its way through Earth´s atmosphere in the direction of the Moon. It appears reddish because of the Rayleigh scattering of bluer light. The round shape of the Earth's shadow visible on the lunar surface was a proof for Aristotle that the Earth must be a sphere. This photo shows the eclipsed Moon that sets near the Rochetta di Prendera, Dolomiti Unesco, Italy, on 21 January 2019.
