Residents in northern China were left astonished as a mysterious black ring appeared in the sky.

The video was filmed in Yulin City in Shaanxi Province on June 17.

The unusual sighting, which lasted for approximately five minutes before gradually dissipating, has sparked widespread curiosity and a flurry of speculation.

According to the eyewitness, the enigmatic black ring was discovered by chance when he looked up at the sky. The ring was described as perfectly circular with sharply defined edges, resembling a colossal black disc suspended in mid-air.

The appearance of the mysterious black ring has prompted a wave of conjecture among both citizens and netizens. Some speculate that it might be a natural phenomenon, potentially a rare atmospheric optical effect or weather anomaly. Others suggest it could be the result of human activities, such as a malfunctioning ground-based device or smoke generated by specific activities.

However, no conclusive evidence has yet emerged to confirm any of these theories.

As of now, no official authorities have provided an explanation for the black ring.
