| Description |
Punta del Este, Maldonado, Uruguay. English: The first of the four consecutive and complete total lunar eclipses (tetrad), to occur in the next two years. The other three will occur Oct. 8 this year and April 4 and Sept. 28, 2015. Tetrads are part of a 565-year cycle. Between 1582 and 1908, there were no tetrads. In this century, there are eight! A total lunar eclipse occurs when the sun, the Earth and the moon are in perfect alignment so that the Earth’s shadow completely covers the surface of the moon. The moon is always a full moon during a total lunar eclipse and it never goes completely dark. It appears reddish for the same reason that sunsets and sunrises often have a red tint. The actual colour of the eclipse is hard to predict because that’s influenced by the levels of pollutants and dust that are floating around the Earth’s atmosphere. The more dust there is, the deeper orange and red will be the colour of the lunar eclipse. As light passes through the atmosphere, the blue colors are scattered out of the path. Red and orange light passes through the atmosphere and is scattered into the shadow zone. If our planet had no atmosphere, then the moon would be completely dark during a total lunar eclipse. Spanish: Este es el primero de los cuatro eclipses lunares totales consecutivos y completos (tétrada), que ocurrirán en los próximos dos años. Los otros tres se producirán el 8 de octubre de este año, y el 4 de abril y 28 de septiembre 2015. Tétradas son parte de un ciclo de 565 años. Entre 1582 y 1908 no hubo tétradas, pero en este siglo tendremos hay ocho! Un eclipse total de Luna se produce cuando el Sol, la Tierra y la Luna están en alineación perfecta, entonces la sombra de la Tierra cubre por completo la superficie de la Luna. La Luna es siempre una luna llena durante un eclipse total de Luna y nunca se va completamente a oscuras. Tiene aspecto rojiza por la misma razón que las puestas de sol y amaneceres a menudo tienen un tinte rojo. El color real del eclipse es difícil de predecir , porque es influenciado por los niveles de contaminantes y el polvo que están flotando alrededor la atmósfera de la Tierra. Cuanto más polvo hay, el naranja se vuelve más intenso y el rojo puede terminar siendo el color del eclipse lunar. Cuando la luz pasa a través de la atmósfera, los colores azules se dispersan fuera de trayectoria. La luz roja y naranja pasa a través de la atmósfera y se dispersa en la zona de sombra. Si nuestro planeta no tuviera atmósfera, la Luna quedaría completamente a oscuras durante un eclipse total de Luna.
