As we have had an inadvertent red theme going on this week, what with poisonous mushrooms and berries, I'll continue with one from the archives again. Taken on the day we moved in. Yeah the unpacking could wait. Set the tripod up, grab the remote and capture the phases of the moon. Much more fun than unpacking.
Red occurs, when bits of light, photons from an astronomical object pass through the Earth's atmosphere, scattering off of particles. To confuse you particles scatter blue light more than they do red light. Blue photons have shorter wavelengths get scattered, and red photons having longer longer wavelengths pass through. Sky objects look redder from Earth than in space, because red wavelengths from the objects, penetrate the atmosphere more so than the blue ones. Also the closer to the earth's horizon, the more noticeable this redness in both the moon and the sun is. Cool eh! Also, apologies to anyone hoping to find "red moon" comic book, book, or computer game here. Wrong blog!
