This is absolutely briliant !
This is very interesting as well as being quite fascinating.............
It is a 24 hour observation of all of the large aircraft flights in the
world, (recorded by the 'plane flight transponders, via Geo-stationary
orbital satellites), patched together and condensed down to about a minute.(viz. what you see
is 24 hrs duration compressed into 1 minute)
From space we look like a bee hive of activity.
You could tell it was summer time in the north by the suns foot print
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 anything like this before this before.
We are taught about the earths tilt and how it causes summer and winter
and have had to imagine just what is going on, now the "tilt" is visable
With this 24 hour observation of aircraft travel on the earths surface we
get to see the daylight pattern move as well across the face of the
planet.
