NASA's NISAR spacecraft captured a clear radar image of East Antarctica showing a landform roughly the width of a major highway cut in the form of a hummingbird in flight. The unusual outline stretches across a broad region, and the radar sweep revealed fine details hidden beneath the surface ice. Scientists say the patterning comes from distant era glacial erosion combined with the land below the ice cap. Scientists describe the result as a quiet reminder of how ice sheets can carve rock into clear shapes over long spans of time. The view was released in mid July as part of NASA's continued work to map Antarctic ice with radar tools. The agency highlights the mission as a useful advance in sheet science. Agency leaders also note that the work refines studies of climate shifts and sea level rise. They say similar passes will run in the next stretch. Pictures like this are likely to draw attention from both experts and the general public. The mission is being run with collaboration across two major government groups. Managers say the satellite was designed to measure small shifts in the ground level. The bird shaped view has already picked up wide internet attention. Many readers said the shape looked almost lifelike.
