Its International Dark Sky Week.
During this week of the new moon in April its a great time to gaze in wonder at the clear night skies having turned off our outside lighting where we can to do our bit to reduct light pollution in the world.
Importantly, light pollution affects so many creatures such as the orientation of nocturnal birds in flight, feeding behaviour of insects, bats, fish and reptiles and even the growth pattern of trees.
While we may not sleep so well with bright street lighting, the International Dark-Sky Association likewise urges action to be taken by governments to heed this disruption to organic life.
At the same time, the economy of energy is an important factor in trying to achieve a global effort at reducing light pollution for the benefit of us all.
