What a total lunar eclipse would look like from the Moon. What would yesterday's (14.4.2014) "blood moon eclipse" have looked like from the surface of the moon? Yesterday was just the first of a rare "tetrad" of lunar eclipses that will occur over the next two years. They're called "blood moons" because Earth's shadow causes the moon to take on the reddish tint you can see here. Image by David Sawell
