Today, June 21, 2018 is the day of the Summer Solstice. It is the longest day in the year in the Northern Hemisphere.
What’s the Summer Solstice you ask? When the Sun shines directly on the Tropic of Cancer, at 23.5 degrees North. The Sun rises really early and sets really late on this day.
So what happens to those in the Arctic Circle on this day? They have sunlight for 24 hours!
Then what happens to those in the Antarctic Circle on this day? They have darkness for 24 hours!
