The light can be seen at the point in the sky that is exactly opposite of the [[Sun]]. It is very hard to see. The light can only be seen from areas with no other lights (away from [[city|cities]]) and on nights with no [[moon]]. This effect is caused by [[matter]] spread around that [[reflection|reflect]] the light from the Sun, and is related to the [[zodiacal light]]. {{wiktionary}} ==Other websites== *[http://antwrp.gsfc.nasa.gov/apod/ap080507.html An image of Gegenschein] {{Sci-stub}} [[Category:Atmosphere]] [[Category:Light]] [[Category:Solar System]]
