NASA-ISRO Satellite Maps Subglacial Mountain in Antarctica, Sparking ‘Hummingbird’ Image

A joint NASA‑ISRO mission using the NISAR (NASA‑ISRO Synthetic Aperture Radar) satellite captured a high‑resolution radar image of East Antarctica that reveals a nunatak called Zaterjavshijsja protruding through the ice sheet. The feature’s shape, highlighted by crevasse patterns, resembles a hummingbird, prompting public interest while confirming it as a real geological formation.

The radar data, combined with gravity measurements, allow scientists to map the hidden topography beneath kilometers of ice, improving understanding of subglacial basins, mountain ranges and potential water networks. These observations provide crucial input for climate‑change models and ongoing monitoring of Antarctic ice‑sheet stability.

The collaboration between the United States and India demonstrates the growing capability of space‑based remote‑sensing to study remote polar regions without disturbing the fragile environment.
