If you live in a big city, you might have noticed that you have trouble seeing the stars. That's because of light pollution, which happens when artificial light is directed towards the sky and reflects back onto earth.
Among various other consequences, it washes out the night sky in urban areas.
Luckily, filmmaker David Lennon has sort of found a solution. Lennon mixed city skylines with the Tasmanian night sky to show a world without light pollution. The amazing results show what cities like Los Angeles, London, and Singapore would look like with all their lights turned off.
