dramatic <\/span><b>red glow of the moon<\/b><span style=\"font-weight: 400;\"> during a <\/span><b>total lunar eclipse.<\/b><\/li>\n<\/ul>\n<h2><b>Occurrence of Blood Moon<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A blood moon occurs when <\/span><b>Earth comes directly between the Sun and the moon<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A process called <\/span><b>Rayleigh scattering<\/b><span style=\"font-weight: 400;\"> causes the moon to appear red instead of dark.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This happens because <\/span><b>shorter-wavelength light<\/b><span style=\"font-weight: 400;\"> (blue) is scattered, while <\/span><b>longer-wavelength<\/b> <b>red light<\/b><span style=\"font-weight: 400;\"> passes through the Earth\u2019s atmosphere, making the moon appear red.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">During totality, \u201cthe entire Moon falls within the darkest part of <\/span><b>Earth\u2019s shadow, called the umbra.<\/b><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When the Moon is within the umbra, it appears red-orange.\u201d This colour shift is what earns the event its nickname, the \u201cblood moon.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Depending on external factors such as atmospheric conditions and <\/span><b>light pollution, the moon, during a blood moon phase<\/b><span style=\"font-weight: 400;\">, may appear red, orange, or copper-coloured.<\/span><\/li>\n<\/ul>\n<h3><b>What is Rayleigh Scattering?<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It was explained by the British Nobel laureate John William Strutt (Lord Rayleigh) in the 19th century.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When light <\/span><b>interacts with particles smaller than its wavelength<\/b><span style=\"font-weight: 400;\">, the <\/span><b>intensity <\/b><span style=\"font-weight: 400;\">of the <\/span><b>scattered light is inversely proportional<\/b><span style=\"font-weight: 400;\"> to its wavelength.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This is the reason the earth sky appears blue: it has the shortest wavelength in visible light.<\/span><\/li>\n<\/ul>\n<p><b>Source: <\/b><a
