Everyone loves to see pretty pictures of Earth, and NASA is no exception. The only difference is that NASA photographs our planet for important reasons. NASA teamed up with the NOAA (the National Oceanic and Atmospheric Administration) to take pictures of the globe from space to better understand things like weather patterns and large-scale human impacts. These photos are mostly taken during the day, but human impact simply doesn't go away at night. This is why NASA and NOAA have decided to use the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi NPP satellite to detect light. When compared to older photos, NASA can which areas in the world are becoming more populated. For more casual photo enthusiasts, the pictures don't offer a practical purpose, but they are still beautiful to look at. Check them out for yourself.
