You won't believe this…

The yellow dots are airplanes in the sky

during a 24 hour period.

You'll be happy you don't fly much anymore!

Stay with the picture.

You will see the light of the day moving

from the east to the west, as the Earth spins on its axis.

Also you will see 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 could tell it was summer time

in the north by the sun's footprint over the planet.

You could see that it didn't quite set in the extreme north

and it didn't quite rise in the extreme south.

I have never seen this before.

We are taught about the earth's tilt

and how it causes summer and winter

and have had to imagine just what is going on.

With this 24 hour observation of aircraft travel on the earth's surface we get to see the daylight pattern move as well.
