The "hummingbird" image of Nunatak Zaterjavshijsja, a mountaintop in East Antarctica. Taken by radar instruments aboard the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite, which can look below the surface. "As the moving glacier passes the obstruction, the mountain’s topography causes stresses in the ice, heavily fracturing the surrounding surfaces with deep cracks, called crevasses, which show as sharp green lines in the image." https://www.nasa.gov/missions/nisar/us-india-satellite-delivers-data-reveals-hummingbird-in-antarctica/ #Science 1/n
