Summary

Dr Maggie Aderin-Pocock and Professor Chris Lintott visit the Van Gogh Immersive Experience to seek inspiration in one of the world’s most famous works of art, Starry Night. How can we mitigate the effects of light pollution so that the beauty of the... (more) night sky captured by Van Gogh might be preserved in the real world for future generations? Images and data from satellites have made it easy for us to visualise the extent of the growing effects of light pollution around the world, but speaking with Professor Kevin Gaston from the University of Exeter, Chris discovers that our current estimates show that global light pollution could be much worse than past data suggests. Without satellites capable of analysing the light emitted from the now-popular bluer LED lighting, he estimates that the true levels of light pollution could be around 200% more than was previously thought. Kevin and Chris discuss how light pollution is not just a problem for astronomers but can have devastating effects
