A SpaceX Falcon 9 rocket launch to deliver cargo to the International Space Station produces a visible “jellyfish” light effect in the U.S., with reports of the glow appearing across the East Coast. Observers described the phenomenon as a bright, cloud-like trail that spreads in the night sky after the launch.
The effect is linked to how exhaust and rocket plume material interact with the upper atmosphere, including light scattering and emission from particles in the wake of the rocket. BBC Science and Space.com both describe the display as striking and widely seen, but with slightly different emphases: BBC highlights the “jellyfish” effect itself, while Space.com focuses on the reach of the sightings and includes accounts based on photos from multiple locations.
Overall, the outlets agree that the “space jellyfish” is a byproduct of a recent SpaceX launch, visible from the ground over a broad geographic area, rather than a separate event or object in space.
