Jupiter : each time closer to us


1) To see: Top, One thought that the great red spot -grs- link (2 times but great than the Earth, 300 years of existence, caught by the probe Galileo/1999-2003), were the unique one of that color in Jupiter.



2) To see middle picture, But now result that in the atmosphere of Jupiter another one exists from recent origin : the little red spot -lrs- link (Gigantic spiral of 9000 km (70% size of the diameter of the Earth, caught in February/2007, by the probe New Horizons: NH link ), in its way towards Pluto (at which it will arrive in the year 2015), according to Hal Weaver link General Manager of the Project NH. The -lrs- developed near the -gmr-, in the last decade, when 3 small white storms merged acquiring suddenly a red color. Some scientists think that the emergency of -lrs- represents a great climatic change in Jupiter. One hopes that the photos and others, contribute to clarify how the storms are developed, change of color and can be controlled (Exo-astronomy).



3) This last photo (click to enlarge) taken by the probe NH, discovers smoke, coming from the Tvashtar volcano link located in the dark part of IO link, a Jupiter moon. Comparativily, the probe Galileo link (2003), not discovered volcanic smoke in any moon of Jupiter. NH discovered another young volcano but without smoke, whose lava as soon as one moved by the moon surface (John Spencer link of the Southwest Research of Institutes in Boulder/Colorado). Of another side, the photos suggest that the jupiterians moons would contribute to maintain thin rings of dust and disintegrated rock in the Jupiter atmosphere, thanks to their capacity of attraction. It is hoped that in the following months, NH, will discovers salty oceans underneath the surface of Europe link (another Jupiter moon), able to lodge life.

Júpiter cada vez más cerca de nosotros.

1) Se pensaba que la gran mancha roja –gmr- (2 veces mas grande que la Tierra, 300 años de existencia, captada por la sonda Galileo : 2003), era la unica de ese color en Júpiter.
2) Pero ahora resulta que en la atmósfera de Júpiter, existe otra, de origen reciente la “pequeña mancha roja” –pmr- (Gigantesca espiral del tamaño del 70% : 9000 km, del diámetro de la Tierra, captada en Febrero/2007, por la sonda New Horizons : NH), en su camino hacia Pluton (a la que arribara en el 2015), según Hal Weaver Director General del Proyecto NH. La -pmr- se desarrollo cerca de la –gmr- despues que en la decada pasada, 3 pequeñas tormentas blancas se fusionaran adquiriendo de subito un color rojo. Algunos cientificos piensan que la emergencia de la -pmr- representa un gran cambio climático en Júpiter. Se espera que fotos y otros, contribuyan a esclarecer como se desarrollan, cambian de color y se controlan estas tormentas (Exo-astronomia).
3) Esta foto tomada por la sonda NH, descubre humo, procedente del volcán Tvashtar ubicado en la parte oscura de IO, una luna de Júpiter. Comparativamente, la sonda Galileo (2003), no descubrio humo volcanico en ninguna luna. NH descubrio otro volcan mas joven sin humo volcánico, cuya lava apenas se desplazaba por la superficie lunar (John Spencer of the Southwest Research of Institutes in Boulder/Colorado). De otro lado, las fotos sugieren que las lunas jupiterianas contribuirian a sostener delgados anillos de polvo y roca desintegrada de la atmósfera de Júpiter, merced a su capacidad de atracción. Se espera que en los siguientes meses, NH, descubra oceanos salados debajo de la superficie de Europa (otra luna de Júpiter), capaz de albergar vida.
