The night is nowhere near as dark as most of us think. In fact, the Earth is never really dark; it twinkles with lights from humans and nature. Read more
Paleontologists use Landsat images and an artificial intelligence to identify sites likely to yield fossils. Read more
Scientists are using novel measurements of gravity to gather indispensable information about Earth’s water supplies. The GRACE mission can see water flowing underground. Read more
Landsat 1 was launched in July 1972, starting the longest continuous observation of Earth's land surfaces from space. Here are some of the memorable scientific and societal contributions from the 40-year-old program. Read more
The world’s longest-running Earth-observing satellite program has collected more than three million images, showing two generations of planetary evolution and of human imprints on Earth. The Landsat archives tell an unparalleled story of our land surfaces. Read more
A dedicated team of scientists has returned to the remote boreal forests of northern Siberia to study how the boreal ecosystem moderates Earth's climate by storing carbon and the implications of a warming climate on those forests. Read more
Launched on May 4, 2002, NASA's Aqua satellite and its six instruments have provided a decade's worth of unprecedented views of our planet. Here are a few of our favorites. Read more
Satellite research shows that the world’s hottest spot changes, though the conditions don’t. Think dry, rocky, and dark-colored lands...and cities. Read more
In 2011, the fourth largest earthquake in history rocked the coast of Japan, spawning a devastating tsunami. Satellites and scientists had an unprecedented view of both. This gallery offers a glimpse of the broad scale of the destruction, of the recovery a year later, and of some new scientific understanding that emerged. Read more
The most-visited images published in the Earth Observatory from 2011 are featured in this gallery. Read more
Earth has a carbon problem, and some think trees are the answer. Would it help to plant more? To cut down fewer? Does it matter where? Scientists are working to get a better inventory of the carbon stored in trees. Read more
