Lough Hyne at night, Co. Cork, Ireland

The sky above Lough Hyne

April 5-12 is the International Dark Sky Week. This week is about being aware of the increasing light pollution caused by artificial light and at the same time getting fascinated by the starry sky. So turn off the lights and discover the night 😉
Light pollution not only interferes with our view of the universe, it also disturbs wildlife, affects human health, wastes energy, and contributes to climate change.

 

My photograph shows Lough Hyne in West Cork on a starry night last August. Not only was the night sky fascinating, there was also the blue glow of plankton around anything that moved in the water – including swimmers and kayakers on a night tour. This natural phenomenon is called bioluminescence and is not uncommon at this marine lake.
