   Explanation: The beginning, middle, and end of a journey through planet
   Earth's colorful umbral shadow is captured in this timelapse composite
   image of a total lunar eclipse. Taken on November 8 from Kitt Peak
   National Observatory this eclipse's 1 hour and 25 minute long total
   phase starts on the right and finishes on the left. Reddened sunlight,
   scattered into the central shadow by Earth's dusty atmosphere produces
   the dramatic dark red hues reflected by the lunar disk. For this
   eclipse, additional reddening is likely due to scattering from ash
   lingering in the atmosphere after a large volcanic eruption in the
   southern Pacific earlier this year. Seen at the right and left, the
   Earth's shadow is still lighter along its edge though. That faint
   bluish fringe along the lunar limb is colored by sunlight filtered
   through Earth's stratospheric ozone layer.
