Very cool video from a different perspective. We are used to observing the night sky from what we feel is a fixed point on Earth. But it isn’t fixed. We are constantly on the move. What if we could view the movement of this planet in relation to a point really far away, itself moving, but far enough that it appears fixed?
An equatorial tracking mount was used for about 3 hours to show Earth’s rotation relative to the Milky Way.
And from Messenger, on its way to Mercury.
