"However, I would have expected the colour bands to be the same for both the Southern and Northern Hemispheres. Otherwise, it’s not fair on the penguins is it.
Sorry, I’d forgotten about Keppler’s second law. Nearer the Sun is faster, so winter is fractionally shorter in the Northern Hemisphere. But it’s still unfair to all but Ecuadorian penguins (unless they prefer winter of course).

"If you count daylight as any time it’s not actually dark, the Polar Regions probably do win."
OK. Why? I'm not asking for any rock-solid logic or computation here. I'm just wondering why this makes sense to you on a gut level.
It’s just because I remember sitting on the 6th seat (wooden box) between astro shots and letting the crew chief sit in my seat for a while on a very boring Atlantic crossing one day in the 70s while I read a winter survival article which made a similar point. The whole crew ended up discussing it for half an hour or so, but I can’t remember exactly what it said. Also, I can remember the the Arctic and Antarctic regions were oft referred to at primary school as "The Land of the Midnight Sun." DaveP
