South Pole Lunar Eclipse
Explanation: The Moon was up continuously for 14 days in August -- when viewed from the South Pole . But during the total lunar eclipse on August 28, it circled only about 10 degrees above the horizon . For Robert Schwarz, the resulting long line-of-sight through the atmosphere that blurred his images was a minor problem when he recorded this four hour long lunar eclipse sequence . A more severe problem was the outdoor air temperature of -68 C (-90 F). The extreme cold required him to make the series of exposures through a slit in a window from inside a heated room. Though the heat produced convection and further blurring, it was the only way to keep the camera at a reasonable operating temperature for an extended period of time. Still, he was rewarded with this impressive record of August's lunar eclipse from a unique perspective on planet Earth .
