Overview

• NASA and Eclipse Wise confirm the next century’s longest solar eclipse on August 2, 2027 with totality lasting about 6 minutes 22–23 seconds.
• A 258 km-wide umbral corridor will cross Spain, Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, Saudi Arabia, Yemen and Somalia, and observers in Mexico and Argentina must use live streams or travel to experience full darkness.
• Observers should protect their eyes with certified ISO 12312-2 solar filters at all partial phases when looking at the Sun.
• Recent viral claims of an August 2025 total solar eclipse were debunked by NASA, which confirms the next solar totality is on August 12, 2026, partly visible from northern Mexico.
• A total lunar eclipse on September 7, 2025 remains the next major celestial event before the 2026 and 2027 solar eclipses.
