Almost the entire population of Egypt lives within a few miles of the Nile.
But my eye is on the green glowing balls on what looks like it might be a solar panel.
Question: What are all these little green glowing balls of (presumably) plasma on this (presumably) solar panel on the ISS? Saint Elmo's fire? Its space station equivalent? What exactly causes it? It looks like an electrical discharge but that's not something you'd normally want to be doing on solar panels, wouldn't there be a preferred pointy thing to discharge the ISS with?
