Video Shows Incredible Phenomenon: Seven Suns in the Sky of Chengdu, China.
An impressive video showing seven suns in the sky of Chengdu, China, is taking social media by storm, leaving users around the world perplexed. The phenomenon, recorded last Sunday, August 18, 2024, was clarified by experts as an optical illusion, but continues to enchant and intrigue thousands of people.
The city of Chengdu, in China, has become the center of attention on social media after a striking video showed seven suns in the sky of Chengdu. The video, captured by a local resident, displays what appears to be several suns aligned on the horizon, creating a surreal scene that quickly went viral. The footage was taken on August 18, 2024, and generated a wave of curiosity and astonishment among internet users.
Phenomenon of the Seven Suns in the Sky of China
Experts consulted by the Chinese newspaper Dimsum Daily explained that the phenomenon of the seven suns in the sky of Chengdu, China, is actually an optical illusion. According to Zeng Yang, vice president of the Sichuan Society for Amateur Astronomy, the effect is caused by the refraction and reflection of light in multiple layers of glass. He emphasized that each additional layer of glass can generate a new virtual image of the sun, resulting in the multiple appearance that was recorded.
To better understand: refraction occurs when light is bent while passing through different materials, while reflection is the return of light upon hitting a surface. In the case of the seven suns in the sky of Chengdu, China, these virtual images appear due to the combination of these two properties of light.
Number of Images of the Sun Can Vary
Depending on the viewing angle and the number of layers of glass involved, the number of images of the sun can vary. This explains why in the video, the suns appear multiple and a little darker. The phenomenon surprised both experts and the public, showing how nature can play visual tricks on our senses.
“What a Wonder Nature Is”
On social media, especially on platform X (formerly Twitter), the reaction was one of pure fascination. Comments like “What a treasure” and “What a wonder nature is” flooded the post, showcasing how the illusion that occurred in China captured the imagination of everyone who watched the video.

Events like this remind us of the complexity and beauty of the natural world. The refraction and reflection of light can create spectacular scenes that, at first glance, seem impossible. This is not the first celestial phenomenon to surprise us. Optical illusions like the parhelion, where bright spots appear beside the sun, or the fata morgana, which distorts the image of objects on the horizon, are other examples of how light can play with our perception.
Even with scientific explanations, the appearance of the seven suns in the sky of Chengdu left a lasting impression. For those who witnessed it, whether live or through the video, the event provided a moment of pure wonder, highlighting the grandeur and mysteries that nature still holds.
