NASA's NISAR satellite captured a sharp radar image of East Antarctica showing a landform roughly the width of a major highway shaped like 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 underneath the ice. The team describe the result as a quiet reminder of how glaciers can carve rock into distinct shapes over long spans of time. The view was released in early July in NASA's continued work to map Antarctic ice with satellite based tools. The agency highlights the mission as a new leap in polar science. Officials also note that the work refines studies of climate shifts and sea level rise. Officials add similar passes will continue in the next stretch. Images like this are set to draw attention from both scientists and the general public. The mission is being run with collaboration between two major space agencies. Managers say the satellite was designed to record tiny shifts in the land elevation. The hummingbird image has already captured wide web based chatter. Several readers said the outline looked nearly lifelike.
