๐ Artificial light is hiding our stars
Artificial skyglow is causing a dramatic change in what people see in the night sky. A 2023 study examined 51,351 naked-eye observations collected between 2011 and 2022. Sky brightness at participating locations is increasing by an average of 9.6 per cent each year. This means a child seeing 250 stars now could see fewer than 100 by age 18. The rate of change depends on light usage and direction, but the trend is clear. ๐
