Moon Phases: An Overview
The phases of the moon are a cultural and astronomical phenomenon that has been intimately intertwined with human history for centuries. Whether serving a practical purpose for agricultural and hunting cultures, or appearing in imagery and stories of folklore, the Moon’s cyclical phases have captivated us since we first looked up in awe. Let’s take a look at what moon phases are and how to determine which one we’re currently in.
What are Moon Phases?
The average 29.5-day lunar cycle is comprised of 8 different lunar phases. As the Moon orbits around Earth, the way it is illuminated by the Sun changes, resulting in different amounts of sunlight reflecting off its surface. This is why we observe different shapes and sizes as the moon waxes and wanes.
The 8 main moon phases, in order, are New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent. As the Moon moves around the Earth, one side is constantly lit up by the Sun, while the other is in darkness. Depending on which side is illuminated, the Moon appears to have a different shape when observed from Earth.
How to Determine the Current Moon Phase
To determine the current moon phase, it’s important to note the day in the lunar cycle, as well as its position in relation to the Earth and the Sun. The best way to do this is by looking up the moon phase for your current date on websites such as NASA’s site or by downloading a moon phase app.
It’s also possible to determine the moon phase based on how much of the Moon’s surface is illuminated by the Sun. The more the Moon is illuminated, the closer the phase is to a Full Moon. The more it is in darkness, the closer it is to a New Moon.
Conclusion
The Moon’s phases have captivated cultures around the world for centuries, inspiring ritual, superstition and literature. Thanks to modern technology, we can easily observe and determine the current moon phase and contemplate the fascination that has accompanied its cycle since time immemorial.
