Seven suns glowing in the night sky over Chengdu, China, stopped people in their tracks and sent social media into a frenzy. On August 18, 2024, at 11:09 PM local time, a woman named Wang filmed this eerie phenomenon from the 11th floor of a hospital in Sichuan’s capital. The video, showing seven bright orbs lined up like a cosmic parade, exploded online, racking up millions of views. Chinese netizens spun tales of ancient myths and modern conspiracies, but experts have pinned down the science behind this jaw-dropping sight.
The footage captured seven glowing spots, each mimicking the sun with varying intensity, visible for about a minute. Shared across Weibo and Reddit, it sparked a wildfire of reactions. Some linked it to the legend of Hou Yi, the archer who shot down nine of ten suns to save Earth in Chinese folklore. Others cracked jokes about global warming, with comments like
“The sun’s got clones now!”
or tossed out theories about magnetic fields and parallel universes. The buzz reflected a mix of wonder, humor, and cultural pride.
Experts, including Zeng Yang from the Sichuan Society for Astronomy Amateur, explained it as an optical illusion. Sunlight hitting the hospital’s layered glass windows refracted and reflected, creating virtual images of the sun. Each pane of glass, likely double or triple-glazed, acted like a mirror, splitting the light into multiple sun-like orbs. The brightest one in the center was the real sun, while the others shifted with the viewer’s angle. This ruled out atmospheric effects like sun dogs, which rely on ice crystals in clouds. The science is straightforward: light bending through glass, not a cosmic anomaly.
Chinese reactions blended awe and skepticism. On Weibo, users marveled at how a window could conjure such a spectacle, with some calling it a “viral spectacle.” The Hou Yi story gave it a cultural twist, with posts joking about needing an archer to “take out the extra suns.” Others wondered if pollution or artificial lights played a role, but experts dismissed those ideas, sticking to the glass-based explanation. The event’s timing, late at night, added to its mystique, as the sun’s low angle likely enhanced the effect through the windows.
This wasn’t a one-time fluke. A similar multi-sun illusion popped up in Qinghai the year before, but Chengdu’s vivid video and viral spread made it stand out. It shows how everyday objects can create extraordinary moments, fueling both scientific curiosity and cultural storytelling.
The seven suns didn’t herald the end of the world or a mythological comeback, but they captivated millions, blending ancient lore with modern science.
