EG in 5F very kindly sent this link to Star Count 2021, which she thought would be of interest for our current space topic. It looks fantastic!
If you are interested in being a 'citizen scientist' and taking part in a star count to help scientists map stars and research light pollution, there is a free digital information pack to download.
Following the guide and the viewfinder that is part of it, you need to locate the star Orion and count all the stars you can see within it. No telescopes needed and it can be completed from your garden or even an upstairs window!
Also included in the pack are other fun activities such as a word search and a recipe for star cookies.
