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 distinctive shape stretches across a broad region, and the radar scan revealed fine details hidden beneath the surface ice. Scientists say the arrangement comes from ancient glacial erosion combined with the land underneath the ice. The team describe the result as a quiet reminder of how ice sheets can carve rock into distinct shapes over long spans of time. The image was released in early July within NASA's continued work to map Antarctic ice with radar tools. The agency highlights the mission as a useful advance in ice science. Researchers also note that the work guides studies of ice loss and coastal risk. Researchers note similar reads will run in the coming months. Pictures like this are expected to draw interest from both researchers and the general public. The mission is being run jointly across two major space programs. They say the satellite was designed to measure subtle shifts in the land elevation. The hummingbird image has already drawn wide web based chatter. Several readers said the outline looked eerily lifelike.
