Blood moon — Image by kenne
A total lunar eclipse will occur overnight on Sunday (Sept. 7) into the early hours of Monday (Sept. 8), creating a striking red ‘blood moon’ for skywatchers across Asia, Western Australia, and Europe. Unfortunately, the Americas missed out on this one. I made the above image ten years ago (September 28, 2015).
The eclipse begins as the moon enters Earth’s penumbral shadow, causing a subtle shading effect. As it moves deeper into the umbra, a dark shadow will creep across the lunar surface until, during “totality,” it turns a reddish-orange hue. The exact shade of the blood moon depends on Earth’s atmospheric conditions at the time of the eclipse. Source: space.com
