This composite image captures the partial lunar eclipse over Capo Sant'Elia in Cagliari, Sardinia, creating a striking interplay between celestial mechanics and historical architecture. In the foreground, the illuminated 17th-century Torre di Calamosca stands prominently atop the rugged, dark terrain. Above, the composite exposure traces the eclipse's progression: near the center, a brilliant full moon casts a warm ambient glow, while higher up, a second lunar disk sits deeply shadowed in Earth's umbra. This characteristic coppery red hue occurs due to Rayleigh scattering, as Earth's atmosphere filters out shorter blue wavelengths of light and bends the longer red wavelengths into the umbilical shadow, illuminating the moon alongside a bright sliver of direct, reflected sunlight.
