However, according to Live Science, Professor Combs explained it was not an actual UFO. This light “jellyfish” escaped from a SpaceX Falcon 9 rocket, launched from Kennedy Space Center in Florida, about 400 km from where the image was recorded.
According to Mr. Combs, it is “the perfect combination of physics and time”.
The “body” of the “jellyfish” actually originates from the exhaust gas released from the rocket engine nozzle. The pressure difference inside and outside the nozzle caused the exhaust gas to expand immediately after leaving the nozzle. This exhaust created the brightest spot in the “jellyfish body”.
Because the rocket launch happened just before dawn, sunlight from just above the horizon hit the exhaust, creating the image of a “jellyfish” with a magical halo.
If you want to see the real so-called “space jellyfish,” you’ll need to look with a telescope to a more distant place – the galaxy cluster Abell 2877, which is famous for its giant light jellyfish that reigns in the sky. , the result of an ancient black hole eruption.
