[Earthview Wonders] No.229: Night Earth 1
NASA released the first new night Earth map “Black Marble” since 2012, with an introductory video.
The nighttime view of the Earth provides researchers with a unique perspective of human activities. By studying Earth at night, researchers can investigate how and why cities expand, monitor light intensity to estimate energy use and economic activity.
