Posted on 08/02/2012 4:09:49 AM PDT by SunkenCiv
Explanation: No star dips below the horizon and the Sun never climbs above it in this remarkable image of 24 hour long star trails. Showing all the trails as complete circles, such an image could be achieved only from two places on planet Earth. This example was recorded during the course of May 1, 2012, the digital camera in a heated box on the roof of MAPO, the Martin A. Pomerantz Observatory at the South Pole. Directly overhead in the faint constellation Octans is the projection of Earth's rotational axis, the South Celestial Pole, at the center of all the star trail circles. Not so well placed as Polaris and the North Celestial Pole, the star leaving the small but still relatively bright circle around the South Celestial Pole is Beta Hydri. The inverted umbrella structure on the horizon at the right of the allsky field of view is the antenna shield for the SPUD telescope. A shimmering apparition of the aurora australis also visited on this 24 hour night.

Reminds me of “The Time Tunnel”.
Remember that one?
Dizzying, but cool!
My favorite show as a kid. That and "The Outer Limits."
I also loved “The Twilight Zone”! :-)
A spud telescope? Those Idahoans are a wacky but innovative people.
All Freepers need to see the Twilight Zone episode "The Obsolete Man". It was one of Burgess Merideth's. All about man vs. state. Very biased to our side. :)
I do, it was a full night for TV back then, seems like “Malibu U” was on after TT. I almost bought the DVD box of that a couple years ago.
Ashleigh Brown designed it I think, but it’s no skin off my nose.
I’m glad that APoD has returned (for now) to non-terrestrial shots, at least. :’)
One of my All-Time Favorites!
