"The new moon embraces the old moon" means that the whole moon surface is faintly visible in the embrace of the curved new moon, which is caused by the reflection of sunlight from the earth's surface to the dark side of the moon. On a clear day, during the waning moon and the moth-eyebrow moon, almost all the bright whole moon surfaces can be seen with the naked eye. When there are other bright celestial bodies near the moon, such as bright stars and comets, the picture will be very beautiful.
Coincidentally, Venus, as the "morning star", happened to appear near this waning moon on the morning of 165438+ 10/3. As the brightest celestial bodies in the sky except the sun and the moon, Venus and the waning moon, the two brightest celestial bodies in the night sky, compete with each other and stand out in the hazy sky. They are the most beautiful scene in the night sky, "Moonlight Express", until the first morning light.

The formation principle of Venus combined with the moon
Venus is the closest planet to the earth, with a radius of 300 kilometers smaller than that of the earth. When Venus rose in the east before dawn, it was called the "morning star" in ancient China. When Venus appeared in the west after dusk, it was called "Chang Geng Xing" in ancient China.
The phenomenon of "Venus combined with the moon" occurs about every 30 days. When Venus is the morning star, the frequency is the same. Every time the moon catches up with Venus, Venus and the moon meet.
When Venus, the moon and the earth are in a straight line, there may be a celestial phenomenon that "the moon covers Venus", and its principle is similar to a total solar eclipse.
