The crescent, a shape that represents fertility, is the name given to the moon’s northern hemisphere.
It is found around the moon and is about one-fifth the size of Earth’s.
The moon has been in a period of rapid activity.
It has a total solar eclipse on Jan. 12.
Scientists say this eclipse has left the moon in an inactive phase and scientists are hoping that the eclipse will change this.
The eclipse also is expected to bring the moon closer to Earth, creating a tidal effect that could slow the flow of water into the ocean and eventually lead to the loss of life on Earth.
Scientists are also predicting that the moon will be the first to return to full eclipse in about 3 million years, after the solar eclipse in December.
