On the 10th anniversary of the launch of NASA's Aura spacecraft, we offer 10 examples of how the satellite has changed our view of dust, pollution, aerosols, and ozone in our atmosphere. Read more
In the summer of 2014, scientists embarked on ship and aircraft expeditions between the U.S. East Coast and Bermuda in order to improve NASA's view of the oceans. Read more
Planes, balloons, and boots on the ground are just some of the approaches NASA scientists are taking this summer and fall in Alaska to investigate the region's changing landscapes, from forests and fire to ice and solar radiation. Read more
In late February 2008, the Wilkins Ice Shelf on the Antarctic Peninsula disintegrated, an indication of warming temperatures in the region. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on NASA's Terra and Aqua satellites provided some of the earliest evidence of the disintegration. Read more
Industrialization has brought incredible societal advances and difficult pollution problems. From space, we can see skies clearing in some regions and darkening in others. The thin blue line of our atmosphere is still quite vulnerable. Read more
The shoreline of Cape Cod provides a visual case study in the evolution and dynamic motion of barrier islands and spits. Read more
The United States has set aside nearly 84 million acres of historic and scenic land in its national parks system. In celebration of National Park Week, here are satellite views of ten of those national treasures. Read more
Field data necessary for validating ocean color satellite data are sparse in many regions of the ocean. NASA scientists will travel over much of the South Pacific between March and May 2014 to fill in this data gap. Read more
Are you distracted by unusual colors in satellite images? They are not photographs, and understanding the difference between them is the key to unlocking the power of false-color images. Read more
It was built to extend a four-decade record of Earth observations. One year after launch, Landsat 8 has deepened the archives and our insights — not just of the land, but of the sea and sky. Here are some of our favorite images to date. Read more
If the cold of winter is getting you down, take flight to some tropical islands. Here are a few of our favorites, as viewed from satellites and the International Space Station. We can take your mind, but you'll need your own travel agent to get your body there. Read more
