NASA satellite images show Antarctic island's skull-like shape after warm winter

NASA has released satellite photographs of Vega Island in Antarctica, where the exposed terrain bears a striking resemblance to a human skull. The images capture large patches of bare ice that were revealed by an unusually warm winter. Scientists studying the region's glaciers have expressed concern about the exposure. Glaciologists warn that the conditions could speed up melting when summer arrives. The case highlights how global warming is visibly altering Antarctica's landscape.
