NASA's Astronomy Picture of the Day for August 1, 2026 featured a photograph by Branko Nadj of a full Buck Moon rising over distant mountains above the Adriatic Sea and the coast of Croatia, captured on July 28 from Krk Island. The Buck Moon is a traditional name for July's full moon.

Because a full moon rises as the Sun sets, Earth's shadow also appears in the twilight scene as a diffuse gray band above the mountainous southeastern horizon. Above it lies the pinkish antitwilight arch, a band of backscattered sunlight more widely known as the Belt of Venus.

According to the accompanying explanation, the New Moon of August 12, 2026 was expected to cast its own shadow on Earth in a much anticipated total solar eclipse. The image was credited to Nadj, with authors and editors Robert Nemiroff, Jerry Bonnell, Cecilia Chirenti and Keighley Rockcliffe.
