NASA's NISAR spacecraft captured a sharp 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 distinctive shape stretches across a broad region, and the radar pass revealed fine details hidden beneath the surface ice. Scientists say the pattern comes from old glacial erosion combined with the land underneath the ice. Scientists describe the result as a quiet reminder of how frozen layers can carve rock into distinct shapes over long spans of time. The view was released in late July in NASA's ongoing effort to map Antarctic ice with radar based tools. The agency highlights the mission as a new leap in polar science. Officials also note that the work helps studies of climate shifts and coastal risk. Officials add similar reads will run in the next phase. Pictures like this are likely to draw notice from both scientists and the casual readers. The mission is being run as a partnership between two major government groups. Managers say the satellite was designed to track subtle shifts in the Earth's surface. The feature itself has already captured wide web based attention. A number of readers said the form looked nearly lifelike.
