NASA's NISAR spacecraft captured a clear radar image of East Antarctica showing a landform nearly 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 scan revealed fine details hidden beneath the frozen layer. Scientists say the pattern comes from old glacial erosion combined with the land beneath the frozen sheet. The team 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 active program to map Antarctic ice with radar tools. The agency highlights the mission as a step forward in ice science. Officials also note that the work helps studies of climate shifts and sea level rise. They say similar passes will keep coming in the next stretch. Photo set like this are set to draw notice from both researchers and the general public. The mission is being run jointly across two major space programs. Managers say the satellite was designed to measure subtle shifts in the land elevation. The bird shaped view has already picked up wide online chatter. A number of readers said the outline looked eerily lifelike.
