We’ve brought you many videos in recent weeks which show fantastic time-lapse scenes (the Aurora and various videos featuring the Milky Way) and all have shown beautifully how the heavens move across the sky in a graceful nightly display…
But that’s not strictly accurate is it? Highlighted below is a new twist on what you’ve already seen, wonderful sky-scapes only this time the heavens remain fixed and it’s the Earth we see moving!
So why is the Earth moving in the above video? Here the frames have been digitally rotated so that it is the stars that stay (approximately) steady, with the Earth moving beneath them. This dramatically shows the actual rotation of the Earth, called diurnal motion, in a clear and moving way.
