Blood moon. The reason why the Moon takes on a reddish color during totality is a process called Rayleigh scattering. This is the phenomenon responsible for the sky to be blue and the sun to appear yellow.

Yesterday waited to see sunset and twilight but came the rain. Today was cloudy and had no Rayleigh scattering. Will be back another day. #geek #nerd #rayleigh #scattering #physics #sunset #twilight #caperachado #portdickson #lighthouse #travel #nature #adventure #astronomy #watch

Blue Sky and Rayleigh Scattering

Roberto Antezana | Wildfire in San Felipe | The sky's blue color is a direct result of Rayleigh scattering which redirects higher frequency (blue) sunlight back into the observer's field of view. Because blue light is scattered more easily than red light, the sun takes on a reddish hue when it is observed through a thick atmosphere, (e.g. sunrise or sunset). Additional particulate matter in the sky can scatter different colors at different angles creating colorful glowing skies at dusk…
