NASA's NISAR satellite captured a detailed radar image of East Antarctica showing a landform roughly the width of a major highway arranged as a hummingbird in flight. The unusual outline stretches across a broad region, and the radar pass revealed fine details hidden beneath the frozen layer. Scientists say the pattern comes from ancient glacial erosion combined with the land underneath the ice. Researchers describe the result as a quiet reminder of how frozen layers can carve rock into distinct shapes over long spans of time. The photo was released in late July as part of NASA's ongoing effort to map Antarctic ice with satellite based tools. The agency highlights the mission as a useful advance in ice science. Researchers also note that the work helps studies of ice loss and sea level rise. Officials add similar reads will run in the next phase. Photo set like this are expected to draw attention from both researchers and the general public. The mission is being run jointly between two major space agencies. Managers say the satellite was designed to track small shifts in the Earth's surface. The hummingbird image has already drawn wide online buzz. A number of readers said the shape looked nearly lifelike.
