Summary[edit]
| Description |
English: How different does sunset appear from Mars than from Earth? For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here side-by-side. A quick inspection will reveal that the Sun appears slightly smaller from Mars than from Earth. This makes sense since Mars is 50% further from the Sun than Earth. More striking, perhaps, is that the Martian sunset is noticeably bluer near the Sun than the typically orange colors near the setting Sun from Earth. The reason for the blue hues from Mars is not fully understood, but thought to be related to forward scattering properties of Martian dust. The terrestrial sunset was taken in 2012 March from Marseille, France, while the Martian sunset was captured in 2015 by NASA's robotic Curiosity rover from Gale crater on Mars.
Español: ¿Cuán diferentes son las puestas de Sol desde Marte y desde la Tierra? A modo de comparación, se hicieron dos fotografías de nuestra estrella común al atardecer, una desde la Tierra y la otra desde Marte. Después se escalaron para tener la misma anchura angular y aquí se presentan una al lado de la otra. Una primera ojeada revela que el Sol parece un poco más pequeño desde Marte que desde la Tierra. Esto tiene sentido, ya que Marte está un 50% más lejos del Sol que la Tierra. Más sorprendente, quizás, es que la puesta de Sol marciana es claramente más azul cerca del Sol que el color típicamente naranja que hay en la puesta de Sol terrestre. La razón de las tonalidades azules de Marte no se entiende del todo, pero se cree que está relacionada con las propiedades dispersivas del polvo marciano. El atardecer terrestre se captó en marzo de 2012 desde Marsella (Francia), mientras que el atardecer marciano fue fotografiado en 2015 por el rover Curiosity de la NASA desde el cráter Gale de Marte. |
