Cloudy weather blocked Seattle’s view of the “super blue blood moon” early today — but as a consolation, skywatchers from Vancouver to Siberia shared their images of the total lunar eclipse.
Total lunar eclipses arise when Earth’s shadow falls fully over the moon, and the long-wavelength light that’s refracted by our planet’s atmosphere turns the full moon’s disk a sunset-like shade of red.
The event received an extra burst of hype because it took place during a time when the moon is closer to Earth than usual (qualifying by some definitions as a “supermoon”), and because it was the second full moon in the course of a month (a so-called “blue moon”).
Putting all these features together results in the super-blue-blood label, which NASA readily adopted. “Sounds like an opportunity for vampires,” University of Washington astronomer Julie Lutz joked.
