Se recomienda seguir el eclipse de sol del próximo día 21 con gafas especiales


Al ser parcial solo será visible con estas gafas que podrán recogerse en la recepción del Museo de la Ciencia y el Cosmos desde el día 16.

El Cabildo de Tenerife, a través del Museo de la Ciencia y el Cosmos, anima a seguir el eclipse de sol que tendrá lugar el próximo día 21 y que desde la Isla se podrá ver como parcial. Ocurrirá justo durante la puesta de Sol y alcanzará un 41% de oscurecimiento máximo, lo que significa que no se percibirá salvo si se elige un lugar donde haya una vista al oeste despejada, antes de la puesta de sol, y con gafas especiales. De esta forma, se podrá ver como si fuera una media luna boca abajo, ocultándose en el horizonte. Las gafas podrán recogerse en la recepción del Museo de la Ciencia y el Cosmos desde el próximo miércoles 16, un máximo de dos gafas por persona.

A las 19:51 (hora local de Canarias) la luna empezará a tocar el disco solar (comienza el eclipse) pero no se apreciará. La luna irá “comiendo” cada vez más al sol hasta que justo cuando ambos toquen el horizonte, a las 20:36 horas quedará poco más de la mitad del sol (el 59%).


Desde Museos de Tenerife, se recuerda la importancia de que nunca se observe el sol directamente sin las gafas adecuadas, ni tampoco durante el eclipse, ni mirar directamente (y menos con prismáticos o telescopios) en ningún momento del eclipse; solo a través de gafas especiales para eclipse (no valen cristales ahumados ni radiografías). Si no se dispone de gafas lo mejor es ver reflejado el Sol en un cacharro de agua, como un cubo. Se podrá fotografiar con el móvil si se ponen las gafas delante de la cámara.

Es peligros mirar con los prismáticos ni siquiera con las gafas puestas en sus ojos. Los prismáticos intensifican muchas veces la luz que nos llega: unos prismáticos típicos 7×50 aumentan los tamaños 7 veces y tienen 50 mm de diámetro. Aunque llevemos las gafas puestas y nos protejan de la luz visible y la infrarroja, están diseñadas para ver a simple vista, no con prismáticos.

I found a sea shell and gave it to my 4 year old daughter and said «You can hear the ocean if you put this to your ear.» She placed the shell to her ear and screamed.
