August Brings 2 Final 2026 Eclipses, With Spain Set for First Total Solar Eclipse in 100+ Years

Q: As a rare double-eclipse month begins tomorrow, what makes the late-August 96-percent lunar shadow completely safe for naked-eye viewing?

It is completely safe to watch the late-August lunar eclipse with the naked eye because you are looking at the Moon, not the Sun. In a lunar eclipse, Earth moves between the Sun and the Moon, and Earth’s shadow falls across the lunar surface. The Moon does not emit dangerous light of its own; it only reflects sunlight, and during an eclipse it actually becomes dimmer as that reflected light is cut off. That makes the event eye-safe throughout, unlike a solar eclipse, when even a tiny exposed part of the Sun can damage eyesight. NASA and other astronomy authorities consistently state that lunar eclipses require no special eye protection. Viewers can safely watch the August 27–28 event directly, and binoculars or a telescope can be used without solar filters to improve the view. This particular eclipse will be especially striking because up to about 96 percent of the Moon will slip into Earth’s dark central shadow, or umbra. That can give the Moon a dramatically darkened appearance, often with a coppery or reddish tint, because some sunlight is bent through Earth’s atmosphere and reaches the lunar surface after blue light is scattered away. The practical concern is not eye safety but viewing conditions: clear skies, a dark location, and knowing the local timing will matter most. That is the sharp contrast with the August 12 total solar eclipse, which must not be viewed with the naked eye except during the brief totality phase.

Only 2 eclipses remain in 2026, both in August: a total solar eclipse on Aug. 12 and a partial lunar eclipse on Aug. 27-28.
Spain is the most populated spot in the solar eclipse’s path of totality, with most of the country seeing sunset totality around 8:30 p.m. CET for roughly 2 minutes.
The moon’s shadow will also bring partial solar views to Alaska, Canada, Iceland, parts of the North Atlantic, some of Europe and the eastern United States.
Up to 96% of the moon’s disk will slip into Earth’s shadow during the late-August lunar eclipse, best viewed across the Americas from Canada and the U.S. to Mexico, the Caribbean and South America.
Viewing conditions differ sharply: the solar eclipse requires certified eye protection, while the lunar eclipse needs only clear skies and darker locations.
