Can you locate your hometown from space? NASA is hoping you can.

The space agency is asking for the public's help in categorizing hundreds of thousands of night photos of Earth. Most of the pictures were taken from the International Space Station. The photos are available in an online collection.

People are asked to identify which cities and towns the clusters of lights are coming from.

Hundreds of volunteers have already classified about 20,000 images, but they need to be confirmed by multiple people. The main goal is to create an open atlas of nighttime photos of Earth.

The photos will be available to the media, the public and scientists.

NASA said the project could help save energy, contribute to better human health and safety and improve the understanding of atmospheric chemistry.

The Complutense University of Madrid is leading the project.
