Almost half a million tourists are heading to Spain to witness a minute and a half of darkness.
The solar eclipse of August 12 will be total in a strip about 300 kilometers wide, stretching from Greenland and Iceland to Spain and Portugal. In Italy, the Moon will only partially cover the Sun's disk, about 50%.
Although the phenomenon lasts very short, only 90 seconds of complete darkness, the fact that it occurs near the Ferragosto holiday is moving hundreds of thousands of tourists, especially to countries on the Iberian Peninsula. There, reservations, led by Chinese tourists, have started to increase a year and a half ago and a hotel room already costs up to 1,200 euros per night.
Spain hasn't experienced daytime darkness since 1905. However, it can now expect three total solar eclipses over the next three years. The one on August 12 will take place between 7:30 p.m. and 9:17 p.m.
The overlap of the Sun and Moon will be gradual, while the total eclipse phase will last only a minute and a half. During this time, temperatures will drop and stars will become visible in the sky. The next eclipses will occur on August 2, 2027 and January 26, 2028.
For the world's second most visited country after France, this will represent another wave of tourists. For sky lovers, it will be a rare astronomical event. The Sun is about 400 times further from Earth than the Moon, but its disk is also about 400 times larger.
That's why, during a total solar eclipse, the two celestial bodies overlap almost perfectly. This phenomenon occurs somewhere on Earth on average every 18 months. However, to see it twice in the same place, you have to wait an average of 375 years.
“A total solar eclipse,” explains Carole Mundell, science director of the European Space Agency (ESA), “is one of those rare moments when millions of people look up at the sky at the same time and feel awe and curiosity. It is a shared moment that connects us to the universe.”
In Spain, many municipalities will organize parties and concerts on the day of the eclipse. They will also set up observation points as far away from artificial lighting as possible and will distribute certified glasses with special filters for observing the Sun.
X-rays, dark bottle caps, or regular sunglasses do not provide protection for the retina from the first and last rays of the Sun that precede and follow the total eclipse. Therefore, providing quality eye protection will be a good investment. After just a few months of waiting, the same glasses can be reused for the other two total eclipses that will follow.
