Lunar Eclipse 2026 Approaches: 'Blood Moon' to Appear Over Americas

Stargazers across the Americas are anticipating a significant astronomical event: a partial lunar eclipse on the night of August 27-28, 2026. Following a total solar eclipse earlier in the month, the moon will take center stage, offering a spectacular 'Blood Moon' phenomenon.

This celestial alignment occurs when Earth passes directly between the Sun and the Moon, casting its shadow upon our natural satellite. According to NASA data, the eclipse will reach its peak intensity when 93% of the lunar diameter is engulfed by the Earth's umbra, the darkest part of its shadow. This extensive obscuration will cause the moon to take on the characteristic coppery and reddish tones that give the event its popular name, 'Blood Moon,' despite it being technically a partial eclipse.

The astronomical display is set to begin on the evening of Thursday, August 27, and extend into the early morning of Friday, August 28. Unlike solar eclipses, which require specific viewing locations for totality, this lunar eclipse will be visible from virtually anywhere in Argentina, provided the moon is above the horizon. Clear skies will be the primary requirement for optimal viewing.

Official timings calculated by NASA indicate the penumbral eclipse will start at 22:24 on August 27. The partial eclipse, where Earth's shadow becomes visibly apparent on the moon's surface, begins at 23:34. The event's climax is scheduled for 01:13 on August 28, with the partial phase concluding at 02:52 and the entire phenomenon ending at 04:02. The partial stage alone is expected to last for three hours and 18 minutes. The reddish and coppery colors are a result of sunlight filtering through Earth's atmosphere, scattering shorter blue wavelengths while allowing longer red wavelengths to reach the moon.
