The Moon has long been a central focus of Earth-related studies, playing an important role in a range of phenomena such as waves. Whether for religious, cultural, or purely scientific reasons, the full moon holds great significance for many people. Scientists believe that the Moon formed about 4.5 billion years ago, shortly after the formation of the Solar System. NASA has proposed that a large object called Theia, about the size of Mars, collided with Earth at this time, resulting in the formation of the Moon. To date, the Moon is the only place outside of Earth that humans have ever visited.

NASA image description
Why is a thin crescent moon not visible far from the horizon? Because the only geometry that gives a thin crescent moon phase is when it appears near the moon. the sun in the sky. The crescent moon is not caused by the Earth’s shadow, but by seeing only a small part of the Moon in direct sunlight. Moreover, the thickest part of the crescent is always in the direction of the sun.
In the evening, a thin crescent moon will set shortly after the sun and won’t be visible for the rest of the night. Alternatively, in the morning, a crescent moon will rise shortly before the sun when it is not visible for most of the night. In the photo from two weeks ago, a crescent moon was near the horizon, before sunrise, far behind the remains of the ancient Temple of Poseidon in Greece.
