An Unmissable Event for Astronomy Enthusiasts in Argentina
If you happen to be in Argentina during the last week of August 2026, prepare for a magical night sky experience. During the late hours of Thursday, August 27, 2026, and the early moments of Friday, August 28, 2026, a partial lunar eclipse will be visible across the entire country. This occurs when Earth aligns exactly between the Sun and the Moon, casting its shadow over our natural satellite.
According to an interview with Adrián González, a Physics and Astronomy professor and science communicator at the Galileo Galilei Planetarium (an iconic cultural landmark in Buenos Aires, Argentina), the phenomenon can be seen nationwide as long as weather conditions permit. Best of all, it requires no special glasses or instruments to protect your eyes.
“In every eclipse, particularly a lunar one, we witness the progression and advance of Earth's shadow over the Moon,” González explained.
Key Timings for the Eclipse in Argentina (ART, UTC-3)
Based on data published by Argentina's Naval Hydrography Service, the eclipse will begin at 11:33 PM on Thursday, August 27 and extend until 2:51 AM on Friday, August 28. The moment of greatest intensity will occur around 1:12 AM, when nearly 96% of the Moon's visible surface will be covered by the darkest part of Earth's shadow.
Citing NASA data, the local news site El Cronista reported that approximately 93% of the lunar diameter will be within Earth's umbra. The eclipsed portion may acquire a dark, coppery appearance.
| Phase | Time (Argentina Time, UTC-3) |
|---|---|
| Eclipse Start | 11:33 PM (Thursday, Aug 27) |
| Maximum Eclipse | 1:12 AM (Friday, Aug 28) |
| Eclipse End | 2:51 AM (Friday, Aug 28) |
Why Does the Moon Turn Red?
One of the most fascinating aspects of this eclipse is that the Moon may display a slight reddish hue. This phenomenon is caused by atmospheric scattering (similar to how sunsets look red): when sunlight passes through Earth's atmosphere, particles scatter the blue tones, while red and orange wavelengths continue their trajectory and project onto the lunar surface.
How to Safely Observe the Eclipse
Unlike a total solar eclipse, a lunar eclipse poses absolutely no danger to human eyesight. You can look directly at it. For the best experience in Argentina, experts recommend:
- Finding an open space, away from tall buildings, with a clear view of the sky.
- Moving away from the light pollution of large cities.
- While binoculars or telescopes are not essential, they will allow you to see the shadow's progression much more clearly.
Free Event at the Galileo Galilei Planetarium in Buenos Aires
If you are in Buenos Aires, the capital of Argentina, the Galileo Galilei Planetarium will open its doors on Thursday, August 27 at 11:00 PM for a free public event. The itinerary includes:
- 10 telescopes supervised by science communicators.
- An accessible station with special telescopes for people with disabilities.
- Live music to accompany the evening.
Attendance is free and on a first-come, first-served basis. In case of cloudy or rainy weather, the event is suspended.
International Visibility and Upcoming Events
According to the National Geographic Institute (IGN) of Spain, this eclipse won't be exclusive to Argentina; it will also be visible in some of its phases from western Asia, Europe, Africa, and the Americas. In Spain, the best conditions will be in the west of the peninsula, the Canary Islands, and Ceuta.
This will be the last lunar eclipse visible in Argentina until June 2029. It arrives just over two weeks after the total solar eclipse of August 12, 2026, which was visible in Spain, Iceland, and other northern hemisphere regions.
