NASA's OMG and Operation IceBridge missions are investigating the thinning of Greenland's ice sheets from both above and below.

As hurricane season unfolds, a helpful set of eyes mounted on the International Space Station allows scientists to observe massive storms from a special angle.

Observations by NASA's IRIS spacecraft suggest that "heat bombs" are going off in the sun's outer atmosphere, helping to explain why the solar corona is so mysteriously hot.

As NASA prepares to send astronauts and spacecraft long distances through space, scientists are keeping an eye on the weather. Space weather.

Since the launch of NASA Earth Observatory (EO) on April 29, 1999, the site has hosted more than 18,000 image-driven stories, featuring everything from the newest satellite imagery to decades-long records of change. This video highlights 25 of our favorite images and data visualizations. The collection represents Earth’s diverse landscapes—deserts, mountains, oceans, and polar regions—along with depictions of human interaction with the environmen

This animation takes the viewer on a simulated journey into Jupiter’s exotic high-altitude electrical storms. Get an up-close view of Mission Juno’s newly discovered “shallow lighting” flashes and dive into the violent atmospheric jet of the Nautilus cloud. The smallest white “pop-up” clouds on top of the Nautilus are about 100 km across. The ride navigates through Jupiter’s towering thunderstorms, dodging the spray of ammonia-water rain, and shallow lighting flashes. At these altitudes -- too cold for pure liquid water to exit – ammonia gas acts like an antifreeze that melts the water ice crystals flung up to these heights by Jupiter’s powerful storms – giving Jupiter an unexpected ammonia-water cloud that can electrify the sky. The animation was created by combining an image of high-altitude clouds from the JunoCam imager on NASA’s Juno spacecraft with a computer-generated animation.

Enveloping our planet and protecting us from the fury of the Sun is the magnetosphere, a key to helping Earth develop into a habitable planet.
