Earth's Moon:

In ancient times, the Moon's surface was believed to be smooth until Galileo Galilei's discovery through his telescope revealed large mountainous regions called lunar highlands, approximately 4.5 billion years old, and numerous craters formed by asteroid impacts. Dark, flat areas known as lunar maria were also observed, formed by volcanic eruptions. In 2018, high-resolution images of the Moon's surface, including craters, were captured by the Saudi Lunar Exploration System during a Chinese space mission.

Orbiting Around Earth:

The Moon completes an orbit around Earth approximately every 27.3 days. Its average distance from Earth is 384,400 km. Artificial satellites and the International Space Station are much closer to Earth than the Moon.

Rotation Around Its Axis and Orbiting Earth:

The Moon takes about 27.3 days to rotate on its axis and orbit around Earth. As a result, the same side of the Moon always faces the Earth, known as the near side, while the other side is called the far side. This phenomenon is analogous to a rotating game, where you need the same duration to spin around a circle and around yourself.

Phenomena Resulting from Relationships between the Sun, Earth, and Moon.

Phases of the Moon:

While the Moon appears in various shapes throughout the month, its actual structure remains unchanged. The changing appearance is due to the varying angles between the Moon, Earth, and the Sun. The Moon's phases, observable changes in its appearance, depend on the positions of these celestial bodies. The lunar cycle takes about a month to go through all its phases, starting with the new moon (conjunction), where the Moon is between the Earth and the Sun, with the illuminated side facing away from Earth. Over time, the illuminated area visible from Earth increases, starting with the crescent, then the first quarter, followed by the gibbous phase, and finally the full moon. During the full moon phase, the Earth is between the Sun and the Moon, taking about two weeks from the new moon phase. Subsequently, over the remaining two weeks in the waning phase, the Moon transitions to the last quarter, then the waning crescent, and finally back to the new moon.

Lunar Cycle:

The phases of the Moon seen from Earth depend on the positions of the Moon, Earth, and the Sun. It takes the Moon about a month to go through all its phases. During this time, only the illuminated portion is visible from Earth, starting with the new moon and progressing through various shapes until reaching the full moon. The moon's cycle, marked by its changing appearance, continues to captivate observers.

Solar Eclipse:

Can you see the TV if someone stands between you and the screen? Sometimes the Moon acts like that person, positioning itself between Earth and the Sun, blocking sunlight from reaching Earth. This phenomenon is known as a solar eclipse. Due to the Moon's smaller size compared to the Sun, it can cause either a partial or total solar eclipse, covering only a small area on Earth (the lunar shadow's diameter does not exceed 269 km). During a total eclipse, which lasts for several minutes, the sky darkens, some flowers close their petals, and bright stars become visible. The outer atmosphere of the Sun, called the solar corona, is also visible during this type of eclipse.

Warning:

 Never look directly at the Sun during an eclipse or under normal conditions, as it can harm your eyes.

What Causes a Solar Eclipse?

Lunar Eclipse:

Sometimes, the Earth aligns directly between the Sun and the Moon, casting its shadow on the Moon's surface. During this time, people in the nighttime region of Earth can witness a lunar eclipse, where the Moon can turn completely or partially dark, with its color often shifting to dark red. On the 14th of Dhu al-Qi'dah 1439 AH, the longest total lunar eclipse of the 21st century occurred. It was observed clearly with the naked eye in Saudi Arabia and many other countries, earning it the name "Century's Eclipse." Lasting around 103 minutes, it is a rare occurrence and was extensively observed by astronomical observatories in Saudi Arabia.

Tides: Ebb and Flow:

The Moon's gravity influences Earth, causing the phenomenon of tides—regular rises and falls in sea level due to the gravitational forces of the Moon and the Sun. During high tide, the sea level rises, and water moves toward the land, while during low tide, the sea level drops, and water recedes from the land. The gravitational effects of the Moon create bulges in Earth's oceans. One bulge faces the Moon, and the other is on the opposite side. Areas not facing the Moon and not on the opposite side experience tidal effects, resulting in shorelines with ebb and flow. Due to Earth's rotation, the positions of tides continuously change.

The Sun's Influence on Tides:

The Sun also affects the processes of tides, but its impact is roughly half that of the Moon due to its greater distance. When the Moon, Sun, and Earth align, causing a straight line, the tide reaches its maximum height, and the ebb is at its lowest. This is known as the spring tide. However, when the angles between the Sun, Earth, and Moon form a 90-degree angle, the tide becomes less, and the ebb increases. This is referred to as the neap tide, where the Sun's gravity reduces the effect of the Moon's gravity.

Conclusion:

1. The Moon appears as an astronomical object that sparks curiosity, harboring numerous puzzles and unique details on its surface.

2. Technological innovations, such as space telescopes and exploration tools developed in modern times, have expanded our understanding of the Moon and its surroundings. These discoveries lead to more questions and research about its origin and impact on our daily lives.

3. Within the dynamic relationship between the Sun, Earth, and the Moon, the noticeable effect of gravity is evident in phenomena such as tides. These natural phenomena not only provide excitement for astronomers and physicists but also play a vital role in shaping the terrain and marine environment.

4. The apparent nature of the Moon varies with its different phases, each revealing a unique beauty and charm. From the new crescent to the full moon, the Moon's phases promote the romance of celestial nights, inspiring poets and artists across the ages.

5. The Moon remains a part of the wonders of the universe, blending art and science, and raising questions about its mysteries and effects on our lives. Our journey in exploring this celestial body reflects the splendor of nature and the marvelous interconnection of planets in our sky.
