A rare NASA satellite image shows 10 sharply defined “dark voids” above Heard Island, a volcanic peak in the southern Indian Ocean. Formed by von Kármán vortices bent nearly 90 degrees by fierce westerly winds, the striking gaps pierce thick cloud cover, offering a vivid glimpse of nature’s intricate atmospheric patterns from space.
