Since the earth is tilted on its axis, the polar regions are
constantly facing the sun at their respective summer solstices and are tilted
away from it in the winter. The
Arctic and Antarctic
circles, at 66.5° north and south latitude, are the southern and northern limits
of the sun remaining above the horizon all day on the longest day of the year.
Between May and early August, no place in the region experiences true darkness.
Conversely, winters are dark with only a few hours of twilight to break the
long polar night.
These pictures were taken between 12:30 and 1:30 a.m.
Yup, that’s when the sun ‘sets’. We tried to get a picture of the sun rising,
which usually happens an hour after it sets, but it isn’t distinctive. It just
looks like late evening.
