Explanation:
With roots on a
rotating
planet, an old tree is
centered in this
sequence of 137 exposures each 20 seconds long,
recorded one night from northern Sicily.
Digital camera and fisheye lens were fixed to a tripod to capture the
dramatic timelapse, so the
stars trailed
through the region's dark sky.
Of course that makes it easy to spot the
planet's north celestial pole.
The extension of Earth's
axis of rotation into space is
toward the upper left, at the center of the concentric star trail arcs.
The Milky Way is there too.
The plane of our galaxy stretches across the wide field of view
from north to east (left to right)
creating a broader luminous band of
diffuse starlight.
