About

The University of Connecticut is a public research university located in Storrs, Connecticut. Researchers at UConn have been studying the Earth's brightness using satellite images, revealing that the planet continues to get brighter every year due to increasing artificial lighting. However, the location and intensity of this progression have become increasingly volatile due to factors such as COVID-19, regulations on light pollution, and economic instability. This research is significant because it sheds light on the impact of human activities on the environment and highlights the need for sustainable practices to mitigate the effects of light pollution. The study's findings were published in Nature and provide valuable insights into the Earth's brightness and its relationship with human activities.
