Night has always been fascinating to people. It provides human and nature psychological balance, and bring us fear, humbleness, curioustiy, as well as perspectives to ourselves and the universe.

However. our experience with night has been profoundly changed during past 200 years ever since Watt lighted up every families. Our modern nocturnal footprint is so bringt that it is detectable from outer space. Cities stop sleeping. Animal and plant't life cycle is disrupted, and people stop being humble and curious. What we have lost isn't just the wonder of the night sky that drowned out in city lights.

In this project, 4 specific night related stories happened in U.S. will be showed and present in the form of data visualization. All the stories are supported by dataset from credible sources. Those stories together will give people a glimpse of what is happening on the other side of the day for both human and nature, and they will give people a new perspective on what should we do at night.
