July 16, 2186 The sky will offer an unprecedented astronomical show: The longest full solar eclipse was registered. So A POT After the analysis of thousands of orbital data. Phenomenon that It will last exactly 7 minutes and 29 seconds, surpass all known historical records and It will not be repeated again in terms of duration, at least another 4000 yearsThe trajectory of the totality (a strip where the sun will be completely hidden from the moon) will cross mainly ColombiaIN Venezuela And Gayana.
Historically, the duration of solar eclipses was very variable. The shortest that was recorded on February 3, 919 and barely passed nine secondsThe field on the contrary, 2186 will not only celebrate the recording of the duration, but also a link to modern astronomical chronology.
Calculations that confirm this
Although the event will take place over a century and a half, The scientific community already considers this a milestoneThe researchers set their date through the field through Complex astronomical calculations that take into account the gravitational interaction between earth, moon and the sun. Thanks to Newton’s Movement Laws Already computing simulations in three dimensions, astronomers can predict solar eclipses with an accuracy of less than a minute in a scale of millennia.
Eclipse of 2186 This will coincide with a particularly favorable geometric combinationThe field that day The Earth will be at its point further from the Sun (Afelio)What will make the sun album perceive a little less. Both, The moon will be in Perigea, its nearest point to the groundwhich increases its obvious size. This alignment will allow the complete occultation of the sun exceptional duration, since the lunar shadow will move more slowly and This will cover a greater expansion of the Earth.
The importance of eclipses for science
NASA emphasizes this The total number of solar eclipses are fundamental for Scientific research during short minutes, when the sun is completely hidden, You can observe the sunny crownThe area of its external atmosphere, which is usually hidden from solar brightness. This analysis of the results Key to understand how energy is transmitted to the sun windA constant flow of particles, which affects both the Earth’s technology and space technologies.
Eclipses are also offered A unique opportunity to study the sunny effects on the Earth’s atmosphereThe field in particular, they allow you to analyze the behavior of the ionosphere, an electrically loaded layer where many satellites and communication systems work, are located in the conditions of darkening. Understanding this dynamics is vital for protecting sensitive infrastructure, such as GPS or telecommunication networks.
Do not wait a century to see the next eclipse
Meanwhile, Spain is preparing to live a series of appropriate eclipses in the next decadesHe is a field August 12, 2026Several cities of the peninsula, such as Corruña, Zaragoza, Valencia or Palma, may observe General solar eclipse since 1912Field The other will follow August 2, 2027 Apparently from Ceuta and Mella, and One end January 26, 2028which will cross Córdoba, Seville and Valencia.
How to watch a solar eclipse
Observation of solar eclipse requires preparation. NASA remembers that the sun should never look directly without adequate protection, even if it is partially coveredOnly glasses with certified filters can be worn out under ISO 12312-2 or indirect methods such as wall -pical projectors. Observation of this type of phenomena is safely safe to avoid irreversible eye damage and enjoy the heavenly show with all guarantees.
