A radar satellite just found an Antarctic “hummingbird” inside a glacier, and scientists say it reveals how ice fractures below the surface
At first glance, it looks like a hummingbird frozen in Antarctica’s ice, but look closer, and the “bird” transforms into something even more remarkable: a mountain buried within a glacier, surrounded by fractures that reveal how one of Earth’s largest ice sheets moves under immense pressure. The striking image was captured by the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite using its L-band radar, which can penetrate snow and image properties of the ice that conventional optical satellites cannot see.
