My son loves Astronomy. Sending this to him.
Didn’t know this could happen!
Flying in a helicopter over the jungle in Sumatra early ‘70s - rainbow ahead - suddenly it was a circle, all the colors visible and we were in the center of it. I stopped telling the story of my experience because no one believed it was true.
I was involved in remote oil exploration for Pertimina, the Indonesian Oil Co.
Nice to have it confirmed. ;-)
Actually, it is physics, not astronomy.
The rainbow is created by light shining on each raindrop which then acts as a prism.
