Cities at Night

NASA has a database with almost half a million pictures taken by the astronauts on the International Space Station. Help create a map of cities at night to study light pollution by interpreting the photographs to determine, for example, if the camera was pointed at a city or the stars...while enjoying beautiful pictures taken from space.

Get started at home or school!


Turn your smartphone into a sensor and measure sound exposure levels in your city. Create an open, geo-tagged Noise Pollution map in the process and help scientists track changes in phenology among other things.

Citizen Science in National Park

Celebrate Citizen Science Day with the Philadelphia Science Festival and the National Park's Every Kid in a Park effort, on Apr 27, 10-3. Make like Lewis & Clark and help create a census of plants, insects and birds all around the National Park! Make cloud observations to ground-truth NASA satellite data, learn why the Liberty Bell's microbes were sent to the International Space Station, and more!

Get started at the National Park in Philadelphia!

Operation Resilient Trees

Monitor urban trees to assess their capacity to adapt to climate change. Just map, identify, and measure the diameter and canopy width of urban trees.

Get started in Los Angeles!

Measure and map the trees in your neighborhood. The information you gather will be used to track green infrastructure around the city.

Get started in New York City!

Excited about urban nature? The City Nature Challenge will be happening in cities across the United States this Spring. Find one near you in the SciStarter Event Finder!
