Satellite captures major ice calving at Greenland's Petermann Glacier
ESA's Sentinel-1 satellite recorded the breaking away of a 29-square-mile section of Petermann Glacier's ice tongue on Aug. 4, 2026. This is the most significant ice loss from the glacier since 2012 and the largest calving event in the Arctic since 2020. Scientists use such observations to study polar changes and their effects on sea levels.
