Light pollution is an environmental issue that you might not think much about, but it can have serious consequences.
From interfering with astronomical research to impacting both wildlife and human well-being, too much artificial light at night can cause a range of problems.
To understand the scale of the problem, the European Space Agency (ESA) is promoting a program to catalog images of cities taken from space and is asking for the public’s help.
The Lost at Night project aims to quantify and map artificial light pollution caused by humans, especially around major cities.
It uses high definition photographs of the Earth taken from the International Space Station (ISS).
“The International Space Station is the best observation point humankind has for monitoring Earth at night,” Kevin Gaston, project leader of Lost at Night, explained to the ESA.
