Fire rainbow
Amazingly beautiful natural phenomenon can be observed when the sun rises high in the sky. The rays of the sun when it passes through high-altitude clouds composed of ice crystals in the form of hexagons. The sunlight is refracted in these crystals in bizarre way, and as a result, we see “fire rainbow”. This phenomenon is not local, it can extend over several hundred square miles.


Lake Lights Up at Night

Bioluminescent splash
What happens to lakes in an area hit by forest fires and floods? Some will glow in the dark.
For a cluster of lakes in Australia's eastern Victoria, the combination of the fire and then the rain washed ash and nitrogen-rich soil into the water. The Gippsland Lakes experienced a rise in sea level. That caused the lakes to mix with sea water, which also raised the salinity.
This recipe led to the introduction of a species of algae called Noctiluca scintillans, commonly known as "sea sparkle." The bioluminescent brew gave the water a nocturnal glow.
