Lava Flows Down Mayon

The OLI (Operational Land Imager) on Landsat 8 acquired this rare, relatively clear image of Mayon, the most active volcano in the Philippines, on Feb. 26, 2026. The natural-color scene is overlaid with infrared observations to highlight the lava’s heat signature.

NASA’s Ready-to-Use Dataset Details Land Motion Across North America

An online tool maps measurements and enables non-experts to understand earthquakes, subsidence, landslides, and other types of land motion. NASA is collaborating with the Alaska Satellite Facility in Fairbanks to create a powerful web-based tool that will show the movement of land across North America down to less than an inch.

NASA Satellite Images Could Provide Early Volcano Warnings

Scientists know that changing tree leaves can indicate when a nearby volcano is becoming more active and might erupt. In a new collaboration between NASA and the Smithsonian Institution, scientists now believe they can detect these changes from space.

5 Surprising NASA Heliophysics Discoveries Not Related to the Sun

With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.
