SpaceX Falcon 9 Launch Creates Stunning ‘Space Jellyfish’ in Twilight Sky

On the evening of February 10, 2025, SpaceX successfully launched a Falcon 9 rocket from Vandenberg Space Force Base in California, deploying 23 Starlink satellites into low-Earth orbit. The launch occurred at 6:09 p.m. PST and was visible across various regions, including Bakersfield and the Coachella Valley.

Observers were captivated by the striking visual display: the rocket's ascent left a luminous, expansive white trail across the twilight sky. This phenomenon, often referred to as a "space jellyfish," occurs when a rocket is launched during or shortly after sunset. As the vehicle climbs through the atmosphere, its exhaust plume expands in the decreasing air pressure and is illuminated by sunlight from below the horizon, creating a glowing, jellyfish-like appearance against the darkening sky.

The unique timing of the launch is crucial for this effect. During twilight, the ground is in darkness while the rocket at higher altitudes is bathed in sunlight. The exhaust particles from the rocket's engines scatter this sunlight, producing the bright, wide trails observed. This contrasts with daytime launches, where the ambient light and atmospheric conditions result in less pronounced plumes.

Such visual spectacles are relatively rare and depend on specific launch timings and atmospheric conditions. They offer both a stunning display for observers and valuable insights into atmospheric optics and rocket propulsion interactions.
