A group of amateur astronomers has planted devices around Missouri to measure how much artificial lighting brightens the night sky. 

The Missouri chapter of the International Dark-Sky Association, formed last year, wants to capture data on light pollution. Satellite imaging shows artificial lighting at night has steadily increased in recent years

There appears to be a “tsunami” of nighttime artificial lighting observed in satellite images that’s increasing from the East Coast toward the middle of the country, said Don Ficken, the chapter’s president.
