NASA releases eBook with insights of earth seen at night from space

NASA has announced its new 200-page eBook, Earth at Night, which includes more than 150 images of Earth in darkness as captured from space by Earth-observing satellites and astronauts on the International Space Station over the past 25 years, the company said.

The images reveal how human activity and natural phenomena light up the darkness around the world, depicting the intricate structure of cities, wildfires and volcanoes raging, auroras dancing across the polar skies, moonlight reflecting off snow and deserts, and other dramatic earthly scenes.

In addition to the images, the book tells how scientists use these observations to study our changing planet and aid decision makers in such areas as sustainable energy use and disaster response.

NASA brings together technology, science, and unique global Earth observations to provide societal benefits and strengthen our nation. The agency makes its Earth observations freely and openly available to everyone for use in developing solutions to important global issues such as changing freshwater availability, food security and human health.
