Lunar phenomena refer to various natural events and features associated with the Moon. These include phases such as the new moon, first quarter, full moon, and last quarter, which result from the changing positions of the Earth, Moon, and Sun. Each phase affects the visibility of the Moon from Earth, creating a cycle that lasts about 29.5 days. Another interesting lunar phenomenon is the occurrence of lunar eclipses. This happens when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. Additionally, the supermoon occurs when the Moon is at its closest point to Earth in its orbit, making it appear larger and brighter in the sky.
