Last week, the world saw a total lunar eclipse – the last one to occur before April 2014. Total lunar eclipses happen as the moon moves behind the Earth and into its shadow, essentially blocking the sun from illuminating the moon. As this gorgeous composite photo shows, the eclipse is visible for several hours, with the full moon rising in crimson as it passes through the atmosphere:

According to NASA:
“The red tint of the eclipsed Moon was created by sunlight first passing through the Earth’s atmosphere, which preferentially scatters blue light (making the sky blue) but passes and refracts red light, before reflecting back off the Moon.”
Every lunar eclipse looks different because the tint and shading depend on the amount of clouds and volcanic dust in the earth’s atmosphere at the time of the eclipse.

I’ll round up the coverage on again in 2014
