Sometimes known as the dark moon, the new moon is when the moon is located right between the Earth and the sun. Because of this, the side of the moon we see receives no direct sunlight, so we can't see it in the sky. We can only see the new moon during a solar eclipse when the moon passes in front of the sun and the moon is silhouetted against the fiery orb. In this photo, a nearly new moon was captured in an image from the International Space Station. "This is what the moon looked like 16 times today," astronaut Ron Garan wrote. The new moon marks the beginning of the month in the Chinese calendar.
