International Women's Day first emerged from the activities of labour movements at the turn of the twentieth century in North America and across Europe. Since those early years, International Women's Day has assumed a new global dimension for women in developed and developing countries alike.
The shadowed portion is entirely hidden from view. The first quarter and third quarter moons (both often called a half moon), happen when the moon is at a 90 degree angle with respect to the earth and sun. So we are seeing exactly half of the moon illuminated and half in shadow.
This phase between Last Quarter and New Moon is called Waning Crescent. You'll soon see a slender crescent in the early morning sky just before sunrise. Earthshine will again be very noticeable. A day or so later the Moon passes between the Earth and the Sun and we once again experience a New Moon and the cycle starts all over. Enjoy watching our Moon as its appearance changes from night to night.
