Stargazers worldwide are preparing for a dramatic total solar eclipse on August 12, 2026, when the lunar disk passes directly in front of the sun, blocking its light and plunging parts of the Earth into daytime darkness. Roughly 15.2 million people spread across Greenland, Iceland, Portugal, Russia, and Spain will lie directly in the path of totality during the celestial event, according to Space. For mainland Spain, it marks the first total solar eclipse in more than a century, with totality approaching close to sunset near the Iberian Peninsula and a small patch of Portugal.
Global Stargazers Gear Up for August 12 Total Solar Eclipse
A further 980 million people—approximately 12% of Earth’s human population—will experience a partial eclipse. Viewers across parts of the U.S., Canada, Europe, and northwestern Africa will see the lunar disk take a bite out of the sun. In the U.K., observers will witness a deep partial eclipse with just over 90% of the sun covered, while regions in Norway, Dublin, Montreal, and several northeastern U.S. states including New York, Maine, and Pennsylvania will also see varying degrees of occultation. The cosmic alignment is part of a broader “Golden Age” of solar eclipses spanning from 2026 to 2028, featuring three total eclipses and three annular ring-of-fire eclipses.
Scientific Expeditions and Atmospheric Research
Space agencies and academic researchers are deploying specialized teams and instruments across the path of totality to study the sun and its impacts on Earth. NASA will send a NASA-funded science team chasing the moon’s shadow aboard a WB-57 high-altitude research aircraft to investigate the dynamics of the sun’s corona. Additionally, the NASA-supported Nationwide Eclipse Ballooning Project is dispatching students from several U.S. universities to Iceland and Spain to launch scientific balloons before, during, and after the eclipse, researching how the temporary darkening affects Earth’s atmosphere. College research teams are launching more than 60 high-altitude balloons from Spain and Iceland for similar atmospheric studies during the temperature drop.
Other scientific endeavors are making use of unique vantage points. Eclipse mapmaker Michael Zeiler will observe his 13th total solar eclipse from a cruise ship in a Greenland fjord as a guest lecturer, pointing a video camera northward to capture potential auroras during totality. Experts emphasize the importance of specialized equipment and safety measures. apnews.com notes that special eclipse glasses are crucial whenever any part of the sun is showing, as staring directly at the sun during partial phases can cause permanent vision loss.
Broadcasting and Live Streaming Plans
For those outside the path of totality, major space organizations and institutions are providing extensive live coverage and webcasts. The European Space Agency is hosting a live broadcast from the Observatorio Astrofísico de Javalambre in Teruel, Spain, alongside a public celebration in Leon. The ESA broadcast will feature Director of Science Professor Carole Mundell, along with ESA scientists Andy To, Miho Janvier, Martin Hewitson, and observatory director Javier Cenarro, highlighting 1 minute and 21 seconds of totality at 20:31 CEST. The agency will also receive live observations from two additional locations within the path of totality.
NASA has scheduled its live stream coverage to begin on Wednesday, August 12, featuring views across the path and interviews with subject matter experts. Totality is slated to begin in Iceland at 1:45 p.m. Eastern and in Spain at 2:28 p.m. Eastern, according to schedules released by NASA. Additional digital coverage will be provided by the Italian-based Virtual Telescope Project and other groups, ensuring global audiences can safely follow every stage of the astronomical phenomenon in real time.
