Lunar eclipse occurs when part or in whole cross-section covered by the shadow of the earth's moon. It occurs when the earth is between the sun and moon on the same single straight line, so that sunlight can not reach the moon because it is blocked by the earth.
In another explanation, a lunar eclipse occurs when the moon is in opposition with the sun. But because the slope of the field of the moon's orbit to the plane of the ecliptic, it is not any opposition to the moon with the sun will cause a lunar eclipse. The intersection of the ecliptic orbit of the moon with the field will bring up the 2 pieces of cut points, called nodes, that is the point where the moon cut out of the ecliptic. 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, solar eclipse will be followed by the second node because it lies on the line that connects the sun with the earth.
Actually, the lunar eclipse event, often months can still be seen. This is because there is still sunlight that is turned towards 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 eclipse of the moon, the moon will appear dark red can be copper, orange, or brown.
Lunar eclipse can be observed with the naked eye and is not dangerous at all.
