Chile Ash Sunset Mt Wellington
Since Chile's Puyehue-Cordon Caulle volcano began erupting on June 4, it has spewed huge plumes of ash and other particles and gas into Earth's atmosphere. Air currents have moved these particles across the skies of the Southern Hemisphere, wreaking havoc on air travel in Australia and New Zealand.
But these diffuse plumes are also treating Southern Hemisphere denizens to stunning sunsets and sunrises by scattering and refracting incoming sunlight in a way that favors the transmission of light closer to the red end of the spectrum.
This phenomenon can be seen in this image of sunset from New Zealand's Mt. Wellington.
