Anonymous users2024-02-08The Earth's shadows are divided into "umbra" and "penumbra". The Moon is orbiting the Earth, and if it enters the Earth's umbra, this shadow will obscure all the sunlight projected on the Moon's surface, and the Moon will appear dim and almost invisible. But if it only passes through the penumbra, which can only block a part of the sunlight projected on the surface of the moon, then we will see that the moon is darker than the original and the brightness is reduced, but not completely invisible, which is a penumbral lunar eclipse.
A penumbral lunar eclipse occurs when the Moon walks into the penumbral region. Since the penumbra is far less dark than the umbra and cannot cover the moonlight, it is generally impossible to see the penumbral lunar eclipse with the naked eye. Astronomy fans who want to see a penumbral lunar eclipse must bring a regular telescope.
Watch the penumbral lunar eclipse at night during the Lantern Festival. The year 2009 is known as the "Global Year of Astronomy", and several beautiful celestial phenomena are about to be staged in the near future. In February, the night sky will be marked by celestial phenomena such as a penumbral lunar eclipse and a conjunction of Venus and the Moon.
On February 9, the day of the Chinese New Year's Day, as long as the sky is beautiful, you can enjoy the penumbral lunar eclipse with the naked eye, starting at 20:36 and lasting for 4 hours, and the best viewing time is about 22:38. According to experts, a penumbral lunar eclipse is an astronomical phenomenon in which the moon enters the penumbra of the earth, that is, the earth blocks part of the sun's light shining on the moon, and the moon's brilliance will become uneven, "darkening and brightening at the same time".

Anonymous users2024-02-06A lunar eclipse is an astronomical phenomenon in which when the Moon moves into the shadow of the Earth, and some or all of the part that could have been illuminated by the sun's rays cannot be illuminated by direct sunlight, making it impossible for observers on Earth to see the ordinary phases of the moon. When a lunar eclipse occurs, the Sun, Earth, and Moon happen to be or almost in the same straight line, so the lunar eclipse must occur on the night of the Full Moon. <

A lunar eclipse is a special astronomical phenomenon that refers to the fact that when the Moon moves to the shadow part of the Earth, the area between the Moon and the Earth will be blocked by the Earth due to the sun's rays, and a piece of the Moon is now missing.
In other words, the sun, the earth, and the moon at this time are just right.
In the case of Earth, when a lunar eclipse occurs, the direction of the Sun and the Moon will be different.
