The path of totality — where the Moon completely blocks the Sun — crosses Greenland, western Iceland, northern Spain, and a small area of northeastern Portugal . A partial eclipse will be visible across most of Europe, parts of Canada, the northern United States, and northwestern Africa . Totality at the Javalambre Astrophysical Observatory in Teruel, Spain, will last 1 minute and 21 seconds, beginning around 20:31 CEST .
Circular Slit Spectrometer (CISS) — An Italian-built instrument undergoing its decisive test at Spain's Javalambre Astrophysical Observatory. It is designed to break down the Sun's light into constituent wavelengths much faster than existing instruments, potentially transforming the study of the solar corona . The eclipse creates conditions where the corona becomes more visible, facilitating studies of the area around the Sun whose behavior can impact communications networks and power grids on Earth .
NASA WB-57 High-Altitude Jet — Flying at 50,000 feet over the North Atlantic west of Iceland, carrying a suite of four cameras in several wavelengths of visible and infrared light . These are the same cameras that flew during the April 8, 2024 eclipse, but with critical exposure-time adjustments to address a documented overexposure failure in 2024 imagery . Flying above most of Earth's atmosphere gives it an unobstructed view of the corona .
NASA Scientific Balloons — NASA-funded teams are launching balloons along the path of totality to study how the sudden darkening affects Earth's atmosphere .
Irish Air Corps C-295 Aircraft — Performing a simultaneous flight with scientists from the European Space Agency and Dublin Institute for Advanced Studies, imaging the Sun's corona using a spare part originally built for an ESA space mission .
ESA's Proba-3 Mission — An artificial eclipse-maker consisting of two satellites flying 150 meters apart, autonomously operating as a single spacecraft . The Occulter spacecraft acts as the Moon, eclipsing the Sun for the Coronagraph spacecraft, which uses its ASPIICS instrument to capture images of the solar corona for hours at a time. Data from Proba-3's ASPIICS coronagraph will be coordinated with ground-based eclipse observations . The mission has been in continuous coronagraphy orbits since July 28, 2026, and will operate through August 19 .
ESA's Solar Orbiter — Its remote-sensing instruments (EUI, PHI, Metis) are taking coordinated images of the Sun's atmosphere in tandem with the eclipse. Planned observing programs include Eruption Watch, Density Fluctuations, and Coronal Hole Boundary Expansion .
ESA's Main Broadcast — A live stream from the Observatorio Astrofísico de Javalambre in Teruel, Spain, combining telescope feeds, drone footage, and expert commentary, starting at 19:30 CEST (1:30 p.m. EDT) on August 12 . Viewers can watch via ESA Web TV or ESA's YouTube channel .
Dedicated Telescopic Feed — A separate continuous telescope-only stream from Javalambre providing close-up views of the different phases of the eclipse without commentary .
NASA's Broadcast — NASA will stream the eclipse live starting at 1:15 p.m. EDT on August 12 via NASA's website .
The root cause is the same New Moon. A total solar eclipse can only occur at New Moon, when the Moon passes directly between Earth and the Sun . The Perseid meteor shower always peaks in mid-August as Earth passes through the debris stream of Comet Swift-Tuttle. In 2026, the New Moon falls on August 12 at approximately 17:37 UTC — the same day as the Perseid peak .
The eclipse happens during daytime (totality occurs in the late afternoon/early evening over Europe). The Perseid meteor shower peaks overnight on August 12–13, just hours later . The predicted peak of the Perseids is 14:53 UTC on August 13, making the mornings of August 12 and 13 the best viewing windows .
The New Moon creates ideal viewing conditions for the meteor shower — exceptionally dark skies with no moonlight to wash out fainter meteors, making this potentially the best Perseid showing in years . Under clear, dark conditions, observers may see 50–100 meteors per hour at the peak .
This exact alignment — a solar eclipse by day and the Perseid peak by night on the same calendar date — is uncommon, though the two events are not physically linked. They are a coincidence of orbital timing . The last time a major total solar eclipse and a major meteor shower peak occurred on the same date is uncertain, but skywatchers widely consider it a rare and valuable double-header .

During the eclipse's brief totality, the Sun's normally hidden outer atmosphere — the corona — becomes visible to the naked eye. Observers in the path of totality will need eclipse glasses or solar filters for all phases except the few seconds of totality itself . For the Perseids, no equipment is needed: find a dark sky site away from city lights, lie back, and look up after midnight into the pre-dawn hours of August 13 . The Perseids are known for bright, fast meteors that often leave persistent trains.
August 12, 2026, offers a rare celestial double feature: a total solar eclipse visible from parts of Europe during the day, followed by the best Perseid meteor shower in years under a perfectly dark new moon. Scientists are deploying a coordinated fleet of aircraft, balloons, satellites, and new ground-based spectrometers to maximize what they can learn from the fleeting moments of totality. For everyone else, there are multiple live streams and, for those in the path, a front-row seat to a 27-year-first.
