Watch it live on the 3D globe

SDGSAT-1 does something almost no other satellite bothers with: it photographs Earth in the dark. Its 'glimmer imager' is sensitive enough to capture city lights, fishing boat lanterns, and offshore oil rig flares at night in full color — data China built specifically to track all 17 of the UN's Sustainable Development Goals, from poverty to clean energy, by literally watching how brightly and where humanity lights up the planet after sunset.
