A netizen in Shandong Province, east China, captured a spectacular "space jellyfish" in the night sky, featuring a glowing, jellyfish-shaped plume.

The phenomenon occurs when sunlight illuminates a rocket's exhaust high in the atmosphere against a darker sky. It lasts only a few minutes.

The Long March-6A rocket lifted off at 6:15 p.m. on Friday, carrying the Yaogan-50 03 satellite into its planned orbit.

To catch a "space jellyfish," conditions need to be just right: a launch shortly after sunrise or before sunset, clear skies near the ground and a viewing location east of the sunset line, where darker skies create a stronger contrast with the sunlit plume.
