On the evening of March 24, 2025, a luminous spiral appeared in the skies over Europe, captivating observers from the UK to Croatia. Social media buzzed with speculation, with some likening the phenomenon to a “portal” or “alien signal.”
What Was It?
The spectacle was caused by a SpaceX Falcon 9 rocket launched earlier that day from Cape Canaveral, Florida. After deploying its classified payload for the U.S. National Reconnaissance Office, the rocket’s upper stage released leftover fuel. This fuel froze into ice crystals at high altitude, reflecting sunlight and creating the visible spiral.
Why the Spiral Shape?
As the rocket’s upper stage spun while venting fuel, the expelled material formed a spiral pattern. This effect, sometimes called a “SpaceX spiral,” has been observed in previous launches but remains rare over Europe. What did SpaceX do?
Public Reaction
Witnesses across Europe shared images and videos, expressing awe and curiosity. Some mistook the spiral for a UFO or other unexplained phenomenon. Experts quickly clarified the cause, attributing it to the SpaceX launch.
The Science Behind the Phenomenon
Such displays occur when rocket launches happen during twilight hours. The contrast between the sunlit exhaust plume and the dark sky enhances visibility, leading to stunning visual effects.

Final Thoughts
While the spiral’s origin was terrestrial, its appearance served as a reminder of the wonders of space exploration and the unexpected beauty it can bring to our night skies.
