    For many people, El Niño and La Niña mean floods or drought, but the events are actually a warming or cooling of the eastern Pacific Ocean that impacts rainfall. These sea surface temperature and rainfall anomaly images show the direct correlation between ocean temperatures and rainfall during El Niño and La Niña events.

  1. Cities at Night: The View from Space April 22, 2008

    Astronauts onboard the International Space Station capture nighttime photographs of city lights, spectacular evidence of humanity's existence, our distribution, and our ability to change our environment.

  2. How on Earth was this Image Made? March 25, 2003

    Remotely sensed Earth observations can include everything from sonar measurements used to map the topography of the ocean floor to satellite-based observations of city lights. Combining observations collected by a variety of instruments at different times and places allow scientists to create an otherwise impossible view of the Earth, showing underwater mountain ranges, cloud-free skies, and city lights that are brighter than daylight. Such visualizations are invaluable for interpreting complex data and communicating scientific concepts.
