I know this isn't strictly astronomy, but it's a lovely time lapse video of sunrises and sunsets in the arctic... and since the Earth is tilted, in the summer the Sun skims just below the horizon as it circles the sky. So hey, I guess it is astronomy related!
You can really see this effect well starting at 1:06 into the video; the Sun sets at a very low angle to the ground, and comes right back up. The sky never gets completely dark. The video was shot by a man who calls himself Mr. TSO, and he has many other lovely videos on Vimeo
. It's Friday, so take some time and look. You'll breathe just a little bit easier if you do.
