NASA Satellites Reveal a Skull-Like Ice and Rock Formation on Antarctica's Vega Island — and a Climate Warning

Landsat 9 imagery of Vega Island in Antarctica shows a striking skull-like formation created by ice, rock outcrops, and glacial moraines, while also documenting extensive bare-ice exposure in October 2026 that scientists say was partly due to above-average winter temperatures, compounded by limited snow accumulation, sublimation, and wind scouring.
NASA's Earth Observatory has published Landsat 9 satellite images of Vega Island, a remote speck of land in the Weddell Sea east of the Antarctic Peninsula, revealing a combination of features that together resemble a smirking skull in profile. A nunatak creates the appearance of an eye socket, a lateral moraine forms a mouth, and Bahía del Diablo (Devil's Bay) Glacier shapes the jawbone. The skull appears to face toward nearby Devil Island. Beyond the striking visual, the images carry a serious scientific message: comparing a March 22, 2025 image with one taken on October 10, 2026, glaciologist Mauri Pelto of Nichols College observed that by October 2026 large areas of the island were bare of snow, leaving darker glacier ice exposed. Pelto said above-average temperatures in winter 2026 — particularly in June — were partly responsible for so much bare ice, with limited new snow accumulation over the winter further reduced by sublimation and wind scouring. This exposed dark ice absorbs more solar energy than snow, creating conditions that could accelerate melting as the melt season progresses. Devil's Bay Glacier has shown an overall decline in mass since continuous monitoring began in the austral summer of 1998–1999, and a comprehensive 1982 study using early Landsat imagery catalogued 29 glaciers on the island, providing a baseline against which researchers can measure ongoing ice losses.
