Lunar Eclipse September 7 stuns skywatchers across the globe
- A blood moon is a total lunar eclipse when the moon takes on a reddish-copper hue instead of its usual white glow.
- During a total lunar eclipse, Earth comes between the sun and the moon.
- Direct sunlight is blocked, but Earth’s atmosphere bends and scatters some light onto the moon – Rayleigh scattering.
- Blue light is filtered out, while red light is refracted toward the moon, giving it a reddish colour.
