    NASA Missions Help Identify What Powers Auroral ‘Space Battery’

    An arc of green aurora bends over the limb of Earth, which appears cloudy. A faint red haze appears above the green auroral arc against the black background of space.

    Scouring archived observations from NASA missions, scientists may have solved a mystery about what powers a type of aurora called auroral arcs. The answer, they say, is space waves. From the ground, auroral arcs look like green, glowing curtains of light sweeping across the night sky. From space, they appear as thin, green lines — or arcs — slicing across the […]

    NASA’s Galileo Mission Points to Ammonia at Europa, Recent Study Shows

    A high-resolution scientific graphic from NASA illustrates the detection of ammonia on the surface of Jupiter’s moon, Europa. On the left, a full-disk view of the icy moon is shown against a black starfield, with a white rectangular box highlighting a specific region near the equator. This box zooms into a large, detailed grayscale map on the right, which reveals a complex landscape of crisscrossing linear ridges and fractured "chaos terrain." Overlaid on this topographical map are pixelated data clusters: purple areas indicate the presence of ammonia, while vibrant red pixels mark the highest concentrations. These detections are primarily concentrated along the geologically active ridges and disrupted ice, suggesting that the ammonia may be surfacing from the moon's subsurface liquid ocean.

    New analysis of decades-old data has turned up a significant result: the first discovery of ammonia-bearing compounds on the surface of Jupiter’s moon Europa. Ammonia is a nitrogen-bearing molecule, and nitrogen — like carbon, hydrogen, and oxygen — is key to life as we know it. As the first such detection at Europa, the finding […]

    NASA-French SWOT Satellite Provides Global Estimate of River Discharge

    A map of the Earth with blue and green lines

    Science teams at NASA and the French space agency CNES (Centre National d’Études Spatiales) have released the first-ever global estimate of river discharge and suspended sediment, as observed from space, marking a new milestone in our ability to understand one of Earth’s most fundamental systems. Developed using data from the SWOT (Surface Water and Ocean […]
