Dark Side Of The Moon – Definition, Discovery, Phases Of Moon

Exploring the hidden realm: Unveiling the dark side of the moon and the captivating phases of our lunar companion

The moon, our celestial companion, has always fascinated humanity with its ethereal beauty and mysterious nature. While we often admire the moon's glowing surface, there exists another side that remains hidden from our view—the dark side of the moon. In this article, we will delve into the definition of the dark side of the moon, its discovery, and explore the captivating phases of our lunar neighbor.

Definition of the Dark Side of the Moon

The term "dark side of the moon" refers to the side that is permanently turned away from Earth, meaning it is never visible from our planet. It is not a reference to literal darkness but rather to the side that remains unseen. The moon's rotation and orbit around the Earth cause it to be tidally locked, which means that the same side always faces us while the other side remains hidden. Consequently, the dark side of the moon is not permanently dark, as it receives sunlight just like the side we see. However, it is often associated with mystery due to our limited knowledge and exploration of that region.

Discovery and Exploration

The discovery of the dark side of the moon can be attributed to the advancement of space exploration. In 1959, the Soviet spacecraft Luna 3 captured the first-ever photographs of the moon's far side. These images provided humanity with a glimpse of the hidden hemisphere, unveiling a stark contrast to the familiar features we were accustomed to seeing. The exploration continued with subsequent missions, such as the Apollo program, which sent astronauts to orbit and land on the moon, expanding our understanding of its enigmatic far side.

Phases of the Moon

The moon, despite its concealed side, still showcases a fascinating array of phases throughout its monthly cycle. These phases are a result of the interplay between the positions of the Earth, moon, and Sun. The four primary phases are the new moon, the first quarter, the full moon, and the last quarter.

New Moon

During the new moon phase, the dark side of the moon faces the Earth, making it completely invisible. This occurs when the moon is positioned between the Earth and the sun. As sunlight illuminates the far side of the moon, it remains hidden from our view.

First Quarter

As the moon orbits around the Earth, a sliver of its illuminated side becomes visible, marking the first quarter phase. During this phase, the right half of the moon appears lit while the left half remains in darkness. The far side remains hidden as it faces away from us.

Full Moon

The full moon phase is perhaps the most captivating and recognizable. It occurs when the entire illuminated side of the moon faces the Earth. The far side is completely concealed during this phase. The moon's luminous beauty during a full moon has inspired countless stories, poems, and artworks throughout human history.

Last Quarter

The last quarter phase is when the left half of the moon appears lit while the right half remains hidden in darkness. This phase occurs before the moon returns to the new moon phase, completing its lunar cycle.
