If you ever watched the sun sink into the horizon and thought "I am actually watching the earth turn" then you'll like this.
This unique planetarium app shows the real-time effects of the earth turning, and makes a visceral connection to our planet's motion.
the Zenith Planetarium shows only the spot directly over your head, magnified about 180x, and without the Sun's glare. Unlike other planetarium apps, there is no pan or zoom, location setting or direction to look. No controls, just stare up at the sky & watch the stars slide across. (...We put the zen in zenith)
At this extreme magnification we easily see the live turning of the earth. This is not a time lapse - just extreme zoom. The stars on the screen are the actual stars over your head.
We use real images from the PanSTARRS telescope on the summit of Haleakalā volcano, Maui, Hawaii.
