What is an Eclipse of the Moon?
Of all the celestial bodies in the universe, the Moon alone ventures into Earth’s shadow. When that happens we see a lunar eclipse. Since this is the only time we can observe the effects of our shadow on another world, it’s a unique experience. Making it even eerier, our planet’s shadow is not black, but red, so the Moon normally turns a vivid coppery color when the eclipse is total. But all lunar eclipse are not the same. The Moon can partly hit our shadow, or it can plunge fully into it. SLOOH sets up its remote telescopes to capture the best of these spectacles – the total lunar eclipse.
How Rare Are Lunar Eclipses?
A total lunar eclipse is never visible to the whole world – only the side that has the Moon in their sky at the time. Moreover, during most years there are no total lunar eclipses at all. After the event of December 11, 2011, there will be none at all during 2012 and 2013. But total eclipses of the Moon will happen in 2014, 2015, 2018, 2019, and 2021. A little more than half of these will be visible from any given place on Earth.
