Lunar eclipse occurs when part or in whole cross-section covered by Earth's shadow. It occurs when the earth is between the sun and the moon on the same straight line, so that sunlight can not reach the moon because it blocked by the Earth.
With other explanations, a lunar eclipse when the moon appeared in opposition to sun. But because of the slope of the field of the moon's orbit to the ecliptic plane by 5 degree , it is not any opposition in the sun will lead to the occurrence of a lunar eclipse. The intersection of the fields of the moon's orbit with the ecliptic plane will bring 2 pieces of cut points called nodes, which is the point at which the moon cut the ecliptic plane. This lunar eclipse will occur when the moon is in opposition to the node. Moon takes 29.53 days to move from one point of opposition to the other opposition point. So it should be, if there is a lunar eclipse, will be followed by a solar eclipse because the two nodes are located on the line connecting the Sun to the Earth.
Actually, the lunar eclipse events, often months can still be seen. This is due to the persistence of the sun's rays are deflected toward the moon by the earth's atmosphere. And most of the deflected beam has a red light spectrum. That is why at the time of a lunar eclipse, the moon will appear dark, can be colored red copper, orange, or brown.
Lunar eclipse may be observed with the naked eye and not dangerous at all.
