Equinoxes and Phenomena

Equinoxes

Equinoxes happen twice a year, around 20 March and 22 September. The word equinox means equal night in Latin because when equinoxes occur, day and night are equal lengths. This happens because the sun crosses the plane of earths equator and earth’s tilt causes it to not point toward the sun or away from it.

Lunar Phenomena

A lunar phenomenon is a colour that appears on the moon. One of the theories about the cause of lunar phenomena is outgassing, which is caused by gas escaping from cavities. They appear as white clouds, haze or reddish shade
