The Earth Story

Mashu Blue This delightful feature is Lake Mashu, found within Akan National Park on Hokkaido Island, Japan. The park is centered on a gigantic volcano, the Akan Volcanic Complex, which is composed of a number of mountains and lakes inside a 20-kilometer wide caldera.

Double Rainbow Caldera This shot of double full rainbows was taken by Jasman Singh Mander after a storm and shared through the US Department of Interior’s feeds. The beginning of a rainbow occurs as sunlight enters a raindrop. As the light enters the water, the light slows down and is refracted, changing path to go towards the center of the bubble. However, not all refractions are the same. White light, as from the sun, contains all the colors mixed together, but when light bends, individual colors will separate, with violet light refracting the greatest and red light refracting the least. These rays of light then hit the far side of the water droplet and reflect back out of the front of the droplet, but in a slightly different direction from where they came in. Thus, the main rainbow comes from light being separated and reflected back, and it shows up when the sun, the water droplets, and your eyes form the correct angle.

The shot covers much of the area of Crater Lake including Wizard Island, vertical wisps of clouds, and the hint of sunlight peeking through. -JBB Image credit: Jasman Singh Mander https://instagram.com/jasmanmander/ US Dept. of Interior: https://instagram.com/usinterior/ https://twitter.com/Interior/status/606117454230609920

There’s a lot going on in this clip. Wildfire, milky way timelapse, and in a national park.
