APOD 4.4

This sequence of images below was taken early Tuesday morning in Waterton Lakes National Park in Alberta, Canada. The peaks in the distance are also part of Glacier National Park, Montana. A series of photographs of the moon shows the progression of a total lunar eclipse- 2014's first. The lunar eclipse was visible for everyone in the Western Hemisphere to enjoy. Each photograph was taken ten minutes apart and captures the entirety of the total phase of the eclipse (which lasted a total of 80 minutes). The image also shows the progression of Spica and Mars across the night sky. Aristarchus, a Greek Astronomer around 270 B.C., was the first to measure the duration of a lunar eclipse (without the aid of modern technology) using simple geometry.
