NASA features decade-long photo collection of full Moon colors from Italy
Published
A NASA daily astronomy feature shows full Moon hues recorded in Italy across a decade and links red, yellow and blue tones to conditions in Earth's atmosphere.
NASA's daily astronomy image feature for November 1, 2026 shows full Moon colors that one astrophotographer documented at various sites in Italy over 10 years, according to NASA.
Reds and yellows usually accompany a low Moon, NASA explains: some blue scatters out along the lengthy path through air that sometimes carries fine dust. A less common blue shade can signal bigger dust particles.
NASA describes the purple Moon's origin as unclear, with a mix of effects possible. It credits air surrounding Earth with bending the light behind the dim red of the July 2018 total lunar eclipse, when the Moon lay in Earth's shadow.
Why it matters
NASA's explanation ties several of these hues to Earth's atmosphere, noting that from beyond it the Moon looks a brownish gray.
