Our trip to the top of Mauna Kea on our vacation was full of science geek fun, but was diminished by the absence of the rest of the Explainers and Paul D.
Because of its height and clear skies, this is apparently one of the best places in the world for astronomical observatories. We didn’t get to go into the research telescopes, but the park guides set up scopes and showed us Saturn and the stars in the Milky Way.
As we were driving down, I think we saw the green flash.
The sky looked much more green than it does in this photo. But to be honest, I’m really not sure whether we saw it or not. According to my guide book (Hawaii the Big Island Revealed), the green flash occurs in super clear skies just after the sun goes down. The light is bent through the thickest part of the atmosphere, splitting into the colors of the rainbow. The green and blue are bent the most, and so you see green in the sky for a few moments. Anyway, I thought of all of you!
