articleThe Brief NASA released a radar image of Antarctica that resembles a hummingbird in flight. Scientists say the image showcases the capabilities of the new NISAR satellite. A striking new radar image captured by the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is turning heads for an unexpected reason: It looks remarkably like a hummingbird. Unlike conventional satellite photography, radar can penetrate snow, ice and clouds, allowing scientists to reveal structures that optical satellites cannot see. Why you should care:The release of the "hummingbird" image comes as NASA and the Indian Space Research Organisation (ISRO) begin making NISAR data publicly available.
