NASA satellites are mapping Earth's nighttime lights with unprecedented detail, revealing dramatic shifts in human artificial luminescence across regions. New imagery shows where cities brighten and darken, exposing the volatile relationship between human activity and light pollution from space.
·NASA's Black Marble satellite data captures the brightest and darkest regions of Earth at night in high resolution
·Nighttime light patterns show dramatic changes over time, tracking human development and energy use globally
·Satellites reveal how artificial light varies volatilely with human activity, economics, and infrastructure shifts
·New mapping techniques allow scientists to distinguish human-made luminescence patterns invisible to ground observers
