Zhe Zhu

Zhe Zhu is a NASA-funded researcher at the University of Connecticut (UConn) involved in a study analyzing satellite images to track changes in Earth's brightness. This research, based on over 1.1 million satellite images taken over nine years, has found that Earth is generally getting brighter each year. Zhu's work is newsworthy because the study reveals that the location and intensity of this brightening have become more volatile, influenced by factors like Covid-19, light pollution regulations, and economic fluctuations. The research also highlights regional variations, with some areas experiencing decreased light pollution due to conflicts, crises, or policy changes. Zhu's findings are significant as they provide insights into global trends in light pollution and its relationship to socioeconomic and geopolitical events, offering valuable data for environmental monitoring and urban planning.
