Understanding the Lunar Phases

The Phases of the Moon

The lunar phases describe the different stages the moon goes through in its cycle around Earth. These phases include the new moon, first quarter, full moon, and last quarter, each with its own unique characteristics. The changes in the moon’s appearance occur due to its position relative to Earth and the sun, affecting how much of the moon’s surface is illuminated.

These lunar phases play an important role in many natural phenomena, such as tides. The gravitational pull between the Earth, moon, and sun causes the ocean tides to rise and fall. The moon's phases have also influenced human culture, with various societies aligning calendars and rituals to the moon's cycle.
