APOD 4.4

The APOD that I chose for this week depicts the recent lunar eclipse seen over from the chilly Waterton Lake in Waterton Lakes National Park in Albert, Canada. Recently, we have been working with a lot of astronomy photography and it is something I have grown to understand and become interested in more. In this photo of the lunar eclipse, there is an exposure of 10 minutes which allowed for the capture of the moon's eclipse phase's position over a period of 80 minutes.The photograph also depicted the star Spica from the constellation Virgo. Something interesting that I learned from this entry was that as early as 270 BC, a greek astronomer by the name of Aristarchus measured the duration of a lunar eclipse. I find it awesome that someone in such an early civilization could do that without the aid of modern clocks and cameras but rather algebraic math.
