Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth’s center of mass is a crucial reference point for satellite navigation and elevation measurements. A team, led […]

Indonesia’s Anak Krakatau
Anak Krakatau erupts ash and volcanic gases in this Sept. 5, 2026, image acquired with the OLI (Operational Land Imager) on Landsat 8. Eruptions are a regular occurrence at Anak Krakatau, a small volcano between the Indonesian islands of Java and Sumatra. Much of its activity remains relatively mild, but it occasionally puts on more […]
Starstruck: NASA Research Shows How Sun’s Ancient History Shaped Earth
At the center of our solar system, the Sun influences every planet that orbits it. In two recent NASA-funded studies, scientists uncovered how ancient events in the Sun’s history may have helped create Earth’s unique climate and driven previously unexplained climatic shifts. In new research, scientists at NASA’s SHIELD (Solar Wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) center — one of […]

NASA Mission Studies Air Pollution Over Ethiopia
A NASA-funded air pollution monitoring network has provided one of the most detailed long-term views yet of the role of black carbon, or soot produced by fires, diesel vehicles, and other combustion sources, in Ethiopia’s capital, Addis Ababa. The detailed measurements show how pollution changes by time of day and season, including increases associated with […]

NASA’s Perseverance Rover Watches Earth Vanish Behind Martian Moon
Earth and the Martian moon Phobos dance together in a series of images recently acquired by NASA’s Perseverance Mars rover. Earth appears as a point of light in the Martian sky, disappearing behind the crescent of Phobos, the larger of Mars’ two moons. This is the first time humanity has captured from the surface of […]
