Understanding Lunar Eclipses : หน้า 147/419

Questions: 1 [48] The lunar eclipse The full moon The eclipse of the moon The lunar eclipse is a natural phenomenon that occurs when the earth blocks the sunlight from reaching the moon, casting a shadow on the moon's surface. This event can only happen during a full moon and when the sun, earth, and moon are aligned. The shadow that the earth casts on the moon can cause it to darken or change color, creating a lunar eclipse. Lunar eclipses are categorized into three types: penumbral, partial, and total. Total lunar eclipses are the most spectacular, where the entire moon passes through the Earth's umbra, giving it a reddish hue often called a "blood moon". This phenomenon has been observed and studied for centuries, providing valuable information about the moon and Earth's atmosphere. (End of excerpt)
