   • 2006, Georgiana Kotarski, Ghosts of the Southern Tennessee Valley, →ISBN, pages 98–99:

     “Because the Earth has an atmosphere, it doesn’t completely block the light on the moon. Some of the red light actually bends through the Earth’s atmosphere and lights up the moon during a total eclipse, and that’s the rusty red, blood moon,” said SubbaRao.

   • 2025 September 6, Priyali Prakash, “Why is a blood moon called so? Sky gazers in India will see a blood moon on September 7 during a total lunar eclipse”, in The Hindu‎:

     Sky gazers in India and in other parts of the world will be able to witness a blood moon on September 7 during a total lunar eclipse. The moon will take on a dark red-copper hue. This is the result of a physical effect called Rayleigh scattering. During a total lunar eclipse, the earth comes between the sun and the moon, blocking direct sunlight from striking the lunar surface. However, not all sunlight is blocked. Only the bluer light is filtered out; the redder light is scattered by the earth's atmosphere, giving the moon its striking colour.
