Frequently Asked Questions

Can we see the Moon during the day?

Yes, the Moon is visible during daytime in the sky, especially near quarter phases when it is far from the Sun in the sky. The Moon is visible about half the time during daytime hours, though often not noticed because daylight is bright.

Why is the full moon sometimes reddish?

During a lunar eclipse, Earth's shadow falls on the Moon. Earth's atmosphere bends sunlight and filters out blue colors, allowing red wavelengths to reach the Moon. This creates the reddish copper color called a blood moon. Regular full moons are white because they are directly in sunlight.

What is a blue moon?

A blue moon is either the third full moon in a season with four full moons, or the second full moon in a calendar month. The Moon is not actually blue in color. The term is simply a naming convention for the extra full moon that occurs occasionally.
