NASA : Spirals in the D Ring .- Espirales en el anillo D,,,,,,,,,,,,,

Hola amigos: A VUELO DE UN QUINDE EL BLOG.,hemos recibido información de la Agencia Espacial NASA, sobre el descubrimiento que realizó la Nave Cassini, sobre unos anillos en D espirales en el planeta Saturno.

NASA, nos dice: "Aunque el anillo D de Saturno es tan delgada que es apenas perceptible en comparación con el resto del sistema de anillos, todavía muestra las estructuras observadas en otros anillos de Saturno. Aquí las estructuras espirales en el anillo D están en exhibición.

Las espirales del anillo D, descubierto en las imágenes de Cassini, se cree que es debido a una deformación en el ring creado a principios de 1980. El mecanismo exacto sigue siendo objeto de debate científico. En el transcurso de la misión Cassini, los científicos han podido observar el devanado espiral cada vez más fuerza a medida que evoluciona. Para más información sobre la espiral, véase PIA12820 y PIA08325...."

Although the D ring of Saturn is so thin that it's barely noticeable compared to the rest of the ring system, it still displays structures seen in other Saturnian rings. Here the spiral structures in the D ring are on display.

The D ring spirals, discovered in Cassini images, are believed to be due to a warp in the ring created in the early 1980s. The precise mechanism remains the subject of scientific debate. Over the course of the Cassini mission, scientists have been able to observe the spiral winding ever more tightly as it evolves. For more about the spiral, see PIA12820 and PIA08325.

(The bright specks and faint vertical streaks are merely image artifacts. The processes typically employed to remove these artifacts would also have degraded the exquisite details of the D ring which are visible here.)

This view looks toward the sunlit side of the rings from about 22 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 6, 2013.

The view was acquired at a distance of approximately 350,000 miles (563,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 131 degrees. Image scale is 2.1 miles (3.4 kilometers) per pixel.
