On the earth, all year long, totally different astronomical phenomena happen that may be seen from Earth, similar to photo voltaic eclipses and meteor showers. Nonetheless, there are additionally others which might be much less identified and simply as fascinating, similar to “days with out shadows.”
The day with out shadow will quickly be seen in a number of areas of Mexico, an astronomical phenomenon that happens when the solar is positioned precisely on the zenith. This occasion happens twice a 12 months within the areas situated between the Tropic of Most cancers and the Tropic of Capricorn, as a consequence of the inclination of the Earth’s axis and the translational motion of the Earth across the solar.
Throughout that day, objects don’t solid any shadows when the solar is at its highest level within the sky. This phenomenon is of explicit curiosity to astronomers and scientists, because it permits numerous measurements and research to be carried out on the connection between the Earth and the solar. As well as, it’s a distinctive alternative for residents to watch a rare occasion of nature.

The day with out shadow has totally different dates in every location, relying on its latitude. In Mexico, the primary cities to expertise this phenomenon will likely be these situated additional south, and it’ll progressively transfer north.
In historical occasions, navigators and explorers used today to make calculations that helped them in navigation and cartography. At present, with GPS know-how, these practices have turn into out of date, however the shadowless day remains to be of nice curiosity to the scientific group.
The shadowless day additionally presents the chance for instructional observations and experiments. Faculties and universities continuously set up actions in order that college students can higher perceive photo voltaic dynamics and their affect on Earth. By watching the shadow of a pole or any object disappear at midday, college students can study ideas similar to the lean of the Earth’s axis, translational movement, and the significance of the solar for our planet.

In Mexico, Shadowless Day happens in two totally different durations annually. The primary interval is between the second half of Might and the primary half of June. The second interval varies between June and August, relying on the precise location inside the nation.
In 2023, Shadowless Day was noticed from Might 23 to 25 in a number of areas throughout the nation, together with Uxmal, Chichén Itzá, Mérida, Dzibilchaltún, and Mexico Metropolis. This phenomenon has a notable affect on the archaeological websites of Mexico, the place the alignment of the buildings permits the phenomenon to be noticed in a spectacular manner. In Chichén Itzá, for instance, the place of the Solar and the construction of the Kukulkan pyramid create a present of lights and shadows that pulls quite a few vacationers and astronomy followers.
NASA calls today “Zero Shadow Day” or Zero Shadow Day (ZSD).
Utilizing the Astronomical Society of India simulator, it may be estimated that the Zero Shadow Days for Mexico in 2024 are on Friday, Might 17 at 1:03 pm and at 1:13 pm on Thursday, July 25 (Central Time). ). The occasions could differ, as this can be a instrument designed primarily to point out when the occasion will likely be in that area of the world.
