But now we know better, and soon, some places around the world will get to see not just an eclipse, but a total solar eclipse. On average, a total solar eclipse occurs every 18 months, but most of the time it’s only visible in hard-to-reach places or even in the middle of the ocean. For some of these regions, it will be the first total solar eclipse in nearly 30 years, or more. Europe’s last total solar eclipse was in August 1999, and this time, most of the continent will once again miss out. So, will you be in one of the countries lucky enough to see the total solar eclipse?
