What about this mysterious pink sky? The sky of Iqaluit, Nunavut mysteriously turned rose on January 13, 2016 afternoon.
So why the strange rose hue in this arctic city in Canada? Residents are baffled.

Here some of the theories from Social medias. Did Ziggy Stardust just flew by? Or could it be because of bad sunglasses? However, the likely answer for the strange colouration isn’t related to pop icons, or eyewear but, it’s rooted in how light reacts with the atmosphere.

Iqaluit’s red sky is likely a result of light scattering, where sunlight is reflected through particles in the atmosphere. The colouring was also likely intensified by the time of day the photo was taken — near sunset — when the sun is lower in the sky.

When the sun is at a low angle in the sky, the light has a longer distance to travel. The blue gets removed by the ice crystals and salt in the air, which leaves red visible.
The clouds are much larger than light waves, which allows them to take on the colour, in this case pink.
