Briefings

NASA Earth Observatory reports Vega Island in the Weddell Sea resembles a grinning skull due to seasonal ice exposure. Images from Landsat 9 captured the island's ice-covered state in March 2025 and its snow-free state in October 2026. A glaciologist noted that above-average winter temperatures in 2026 caused significant ice loss, reducing snow accumulation and accelerating melt. The island's unique features, including a nunatak resembling an eye socket and a glacier forming a jawbone, were identified in the 1982 study by Rabassa et al.

Key points

• Vega Island in the Weddell Sea displays a skull-like appearance with a nunatak resembling an eye socket and a glacier forming a jawbone.
• Landsat 9 imagery from March 22, 2025 and October 10, 2026 revealed the island's ice conditions, with October showing snow-free surfaces due to above-average temperatures.

Context

Vega Island is an ice-covered Antarctic speck located east of the Antarctic Peninsula, known for its unique glacial features. The 1982 study by Rabassa et al. cataloged 29 glaciers on the island, with Devil's Bay Glacier closely monitored for mass decline since 1998-1999. The images illustrate the island's eerie countenance at the start of austral autumn and in spring, highlighting the contrast between snow-covered and snow-free states.

Limitations

Evidence is limited to two Landsat 9 images from 2025 and 2026, with no data on historical ice conditions prior to 1982. The study by Rabassa et al. (1982) is preprint status and may contain uncertainty regarding glacier inventory details. Specific mass balance measurements for Devil's Bay Glacier are not provided in the source evidence.
