Be a cosmic citizen scientist!

26th January 2023

Sign up for the CPRE 2023 Star Count 17-26 February.

Since the dawn of civilisation starry skies have filled people with wonder.

But one of the most magical sights our countryside offers is no longer really easy to see. Sadly, light pollution is leaving fewer stars than ever visible to the naked eye.

Light pollution is driving the rapid decline in insect species. It disrupts bird migration at night and the daily rhythm of nocturnal species. It also wastes energy in a climate emergency. Read more:

We need your help to track how light levels are changing – so that we can work towards reclaiming dark skies for people and wildlife.

How to become a cosmic citizen scientist

Take part in CPRE’s Star Count, a cosmic census to map light pollution.

Choose a clear night between 17-26 February 2023 and look to the skies to count the stars within Orion.

Before the Star Count you’ll have lots of guidance so you know where to look! And you don’t need a telescope.

So calling kids and adult stargazers, sign up for the Star Count:
