Lunar eclipse over Paranal Observatory

Star trail during the last total lunar eclipse, as viewed from Paranal Observatory. The sequence starts at 1:08 am Chilean time, when the Moon was roughly half way into the Earth’s umbra, and ends at 3:18 am, when it was half way out. This is my first star trail ever, and I was rather nervous about getting the settings right, as the illumination changes a lot during the eclipse.


The red color of the Moon is due to the Earth’s atmosphere: as sunlight passes through the atmosphere, blue light is scattered away whereas red light goes through. This is the same reason why the sun appears red at sunset and sunrise. In fact, if you were on the Moon during a lunar eclipse, you’d see the Earth surrounded by a bright red ring: you’d be literally seen all sunsets and sunrises all over the world simultaneously!


Did you get to see this eclipse? What did you think?
