SUMMARY
The NISAR satellite, a collaboration between NASA and ISRO, has captured a striking image of a large "hummingbird" shape on the Antarctic ice. This visual is created by radar imaging, which uses varying colors to represent different ice topography and fractures. Magenta indicates smooth ice, while sharp green lines denote crevasses. The feature is actually a geographical formation known as Nunatak Zaterjavshijsja, a mountaintop around which ice flows, stressing the ice and creating the visible fractures. NISAR's radar can penetrate snow and ice, revealing details hidden beneath the surface.
TAKEAWAYS
A joint US-Indian satellite, NISAR, captured an image resembling a hummingbird on Antarctic ice.
The image uses radar technology, with magenta for smooth ice and green for crevasses.
The "hummingbird" is a representation of a geological feature called Nunatak Zaterjavshijsja and ice flow.
NISAR's radar can reveal details beneath the ice surface, providing insights into glacier movement.
