The yellow dots are airplanes in the sky during a 24 hour period.
You can see the light of the day moving from the east to the west, as the Earth spins on it's axis, the aircraft flow of traffic leaving the North American continent and travelling at night to arrive in the UK in the morning. Then you will see the flow changing, leaving the UK in the morning and flying to the American continent in daylight.
It is a 24 hour observation of all of the large aircraft flights in the world, condensed down to about 2 minutes. From space we look like a bee hive of activity!
You can tell it is summer time in the north by the suns foot print over the planet - the sun doesn't quite set in the extreme north and it doesn't quite rise in the extreme south.
