NASA : Hubble Sees New Dark Spot on Neptune .- Telescopio Espacial Hubble ve Punto Nuevo Oscuro en Neptuno

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Nuevas imágenes obtenidas el 16 de mayo de 2016 por el telescopio espacial Hubble de la NASA confirman la presencia de un vórtice oscuro en la atmósfera de Neptuno. Esta imagen en luz visible completa muestra que la formación oscura reside cerca y por debajo de un grupo de nubes brillantes en el hemisferio sur del planeta. A pesar de características similares se observaron durante el Voyager 2 sobrevuelo de Neptuno en 1989 y por el telescopio espacial Hubble en 1994, este vórtice es el primero que se observa en Neptuno en el siglo 21.

New images obtained on May 16, 2016, by NASA's Hubble Space Telescope confirm the presence of a dark vortex in the atmosphere of Neptune. This full visible-light image shows that the dark feature resides near and below a patch of bright clouds in the planet's southern hemisphere. Though similar features were seen during the Voyager 2 flyby of Neptune in 1989 and by the Hubble Space Telescope in 1994, this vortex is the first one observed on Neptune in the 21st century.

 

Neptune's dark vortices are high-pressure systems and are usually accompanied by bright "companion clouds," which are also now visible on the distant planet. The bright clouds form when the flow of ambient air is perturbed and diverted upward over the dark vortex, causing gases to likely freeze into methane ice crystals.
