A mountain peak in East Antarctica looks exactly like a hummingbird in flight. NASA's NISAR satellite radar captured the image, and scientists are calling it Nunatak Zaterjavshijsja.
A mountain that looks like a bird
The peak is called a nunatak, a rocky outcrop that pokes through ice. It sits in East Antarctica, surrounded by a stream of ice flowing northeast toward the ocean. The L-band radar on NISAR, a joint U.S.-India satellite, produced the image. The radar sees through clouds and darkness, revealing shapes that visible light cannot.
Why locals and scientists care
Antarctica has no permanent residents, but researchers stationed there pay close attention to such features. Nunataks help scientists study how ice moves and how the continent's geology interacts with its ice sheet. The hummingbird shape is a coincidence of erosion and ice flow, but it draws attention to a remote part of the world that is critical for understanding sea level rise.
What the radar reveals
NISAR's L-band radar can penetrate snow and ice, giving scientists a clear view of the land beneath. This image shows the nunatak standing out against the surrounding ice stream. The radar data helps researchers track changes in ice velocity and surface features over time. The hummingbird shape is not just a curiosity. It is a marker for how ice flows around obstacles, which affects how fast ice moves to the ocean.
The image is a reminder that even in the most isolated places on Earth, unexpected patterns emerge. NISAR continues to orbit, sending back data that reveals both the beauty and the mechanics of a changing planet.
