This was a SpaceX Falcon 9 Block 5 launch from Cape Canaveral that occurred around 1900 local time on March 4th, 2024. The photo was taken from about 65km from the launch site. The rocket was in the 2nd stage.
Here’s a video of the launch, but you can’t really see the aura since the video is taken from the ship pointing at the rocket nozzle.
It’s a space jellyfish!
No, really, that’s the name for that phenomenon: https://en.wikipedia.org/wiki/Space_jellyfish
