Looking down over the lake at the foot of Angel Glacier on the north face of Mount Edith Cavell. Originally named due to its distinctive appearance in the form of an angel it is melting rapidly and is no longer connected to the ice on the lake below. It will eventually disappear completely from the face of Mount Edith Cavel. Jasper National Park, Alberta, Canada.

The full power of the sun’s rays just starting to hit the moon again after a total lunar eclipse on the 20th Jan 2019. The blood moon colour you see during lunar eclipses results from some of the longer wavelength red tones passing though the sides of the earth’s atmosphere while the majority of the shorter wavelength blues are blocked out. This is due to Rayleigh scattering which is the elastic scattering of sunlight through the earth's atmosphere. The amount of scattering is inversely proportional to the fourth power of the wavelength, so the longer wavelength warmer tones passes straight though the atmosphere without significant deflection, while the shorter blue wavelengths are scattered in all directions. This is the same phenomena that you see when looking across the long stretch of atmosphere directly into the sun at sunrise and sunset giving the sky its red/orange colour. The scattered blue tones absent at sunrise and sunset are what gives the sky its blue colour during the day.
