Satellite spots a 'hummingbird' in Antarctica photo of the day for July 23, 2026

Satellite data from the NASA-ISRO Synthetic Aperture Radar (NISAR) mission has produced a striking image of Antarctica that resembles a colorful hummingbird. While the shape captures the eye, the science behind it offers a critical look at the continent's changing landscape.

The 'bird's body' at the center of the image is the Nunatak Zaterjavshijsja mountain in East Antarctica. The structures appearing as feathers are actually deep crevasses formed by glaciers fracturing the mountain surface as ice flows toward the ocean. A stream of ice marks the 'tail' as it moves northeast.

Radar technology allows experts to see through snow and deep into the ice, revealing properties invisible to standard optical cameras. This capability provides researchers with a clearer understanding of how glaciers move and react to environmental shifts. By observing what remains hidden beneath the surface, the mission tracks tiny changes on the Earth's surface.

NASA and ISRO recently made this radar data available to the public. As mission teams continue to share these findings, researchers across the globe now have access to precise tools for studying the stability of Antarctic ice. The data serves as a resource for those monitoring the effects of a changing climate on polar regions.
