Explanation:
You can pack a lot of sky watching into 30 seconds on this tiny planet.
Of course, the full spherical image timelapse video
was recorded on
planet Earth, from
Grande
Pines Observatory outside Pinehurst, North Carolina.
It was shot in early September with a single camera and circular
fisheye lens,
digitally combining one 24-hour period with camera and lens pointed up
with one taken with camera and lens pointed down.
The resulting image data is processed and projected onto
a flat frame centered on the
nadir,
the point directly below the camera.
Watch as clouds pass, shadows creep, and the sky cycles from day to night
when stars swirl around the horizon.
Keep watching, though.
In a second sequence the projected center is the
south celestial pole,
planet Earth's axis of rotation below the tiny planet horizon.
Holding the stars fixed, the horizon itself rotates as the tiny
planet swings around the frame, hiding half the sky
through day and night.
