This Sunday, over 7 billion people worldwide will witness a breathtaking lunar eclipse. During this event, the Moon will turn a dramatic red hue, an effect known as the ‘Blood Moon.’ But that’s not all skywatchers can look forward to this weekend.
What Makes the Moon Turn Red?
The red color appears when the Earth moves between the Sun and the Moon. Earth’s atmosphere bends sunlight, filtering out blue wavelengths and allowing red light to reach the Moon’s surface. This is why the Moon glows with a coppery red shade during an eclipse.
Spotting the Rare Blue Band
While everyone under clear skies can see the red Moon, only a lucky few will catch the rare blue band. This phenomenon, caused by the ozone layer filtering red light, creates a subtle blue rim around the shadow. To see the blue band, viewers must be in the right place at the right time, under ideal atmospheric conditions. If you’re hoping to catch this unique sight, seek out clear, dark skies and keep your eyes peeled as the eclipse unfolds.
