At 4:30 a.m. on April 20, the lanterns of the Guling Mountain City in Lushan, Jiangxi Province were bright, and the stars in the night sky were shining. In the southeast, the observer could clearly see with the naked eye, Jupiter, Venus, Mars and Saturn from low to high. Arranged from left to right, almost equally spaced in a straight line, the rare "four-star in a row" astronomical landscape is staged.
At around 5:30, as the rising sun dyed the sky red, the "Four Stars" disappeared into the sky, and the whole landscape lasted for about an hour.
According to astronomy experts, the reason why it is worth watching this time is because the four bright planets visible to the naked eye are connected in a very narrow range, and this happens only once every few years.
