Manatee County residents who looked toward the sky early Tuesday morning, October 13, were treated to an extraordinary sight as a SpaceX rocket launch created a massive, glowing cloud that resembled a jellyfish floating above the horizon.
The unusual display followed the launch of a SpaceX Falcon 9 rocket at 6:33 a.m. from Cape Canaveral Space Force Station on Florida’s east coast. The rocket carried an uncrewed Dragon spacecraft loaded with supplies and scientific equipment destined for the International Space Station.
As the rocket climbed into the upper atmosphere, its exhaust expanded into a brilliant, swirling cloud of blue-white light. Photographs taken in Manatee County captured the remarkable formation, including wispy, feather-like patterns, bright illuminated sections and reddish-orange trails stretching toward the horizon.
The phenomenon, commonly known as a space jellyfish, occurs when a rocket launches shortly before sunrise or shortly after sunset. Although the sky remains dark for observers on the ground, sunlight is already reaching the upper atmosphere because of Earth’s curvature.
As the rocket travels higher, its exhaust gases and water vapor expand rapidly in the thin atmosphere. Some of the water vapor forms tiny ice crystals, while sunlight illuminates the expanding plume. The combination produces a glowing cloud that can resemble a jellyfish, complete with a rounded body and delicate, trailing tentacles.
The striking blue and white colors are created by sunlight scattering through the expanding exhaust plume. Changes in altitude, atmospheric conditions and the angle of sunlight can produce different colors and patterns. Winds at high altitudes also help stretch and distort the cloud as it spreads across the sky.
Tuesday morning’s relatively clear conditions allowed the display to be seen across a large portion of Florida, including the Gulf Coast. Residents in communities throughout Central and Southwest Florida photographed the unusual formation as it expanded and gradually faded.
The launch was part of NASA’s 35th commercial resupply mission with SpaceX, designated CRS-35. The Dragon spacecraft is transporting more than 6,300 pounds of scientific experiments, equipment and supplies to the International Space Station. The spacecraft is scheduled to arrive on Thursday, October 15.
Although the glowing formation appeared unusual, it was a normal atmospheric effect associated with rocket launches during twilight. The expanding plume was not a meteor, an unidentified flying object or an indication of a rocket malfunction.
For Manatee County residents fortunate enough to witness the early morning spectacle, the launch offered a dramatic reminder that space missions departing from Florida’s east coast can create remarkable views hundreds of miles away.
The photographs captured Tuesday morning show how a routine spaceflight can briefly transform the predawn sky into an extraordinary natural light display.
