Glossary term: 식
Description: 식현상은 천체가 다른 천체의 그림자 속으로 들어가거나 다른 천체가 관측자와 다른 천체 사이를 지나가면서 일시적으로 가려질 때 발생합니다. 식현상의 예로는 지구가 태양과 달 사이에 있고 달이 지구의 그림자 속으로 이동하는 월식이나, 달이 지구와 태양 사이를 이동하면서 태양빛의 일부 또는 전부를 가리는 일식이 있습니다. 가려진 천체가 다른 천체의 일부분만 가리는 경우 이 현상을 통과(transit)라고 하며, 가려진 천체가 다른 천체를 완전히 가리는 경우 이 현상을 엄폐(occultation)라고 합니다.

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.
