The sombrero Galaxy in infrared

Explanation: This floating ring is the size of a galaxy. In fact, it is part of the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light. The above image shows the infrared glow, recently recorded by the orbiting Spitzer Space Telescope, superposed in false-color on an existing image taken by NASA's Hubble Space Telescope in optical light. The Sombrero Galaxy, also known as M104, spans about 50,000 light years across and lies 28 million light years away. M104 can be seen with a small telescope in the direction of the constellation Virgo.

David. ¿Quién sabe? Lo que se vé en esta imágen parece una erupción desde el interior y forma un monticulo, lo que evidencia que es solido o que el liquido está helado. También podria ser un despeñado.

Claro,no me refiero a que se aprecia agua en el momento de ser tomada la foto.Esa escorrentia que se ve tiene que haber sido causada por un liquido.Nos queda mucho por conocer...

Explanation: What created these white ridges on Mars? The images showing the white ridges, including some of the highest resolution images ever taken from Martian orbit, were recorded last year by the Mars Reconnaissance Orbiter (MRO). A current leading hypothesis is that the white ridges formed as water flowed through underground cracks and bleached and hardened the edges of surrounding rocks. Over millions of years, surface winds eroded the darker rock leaving the raised white ridges. Such water-created light-colored markings are well known here on Earth. The hypothesis is particularly interesting as underground water could have helped to support microbial life on the red world. The above image resolves surface features as small as one meter across in Candor Chasma region of huge Valles Marineris on Mars.

Traducción abreviada:
La hipotesis actual dominante es que los meandros o cauces blancos formados como agua crriente por el subsuelo, golpeó, blanqueó y endureció los bordes del entorno rocoso. Durante millones de años, los vientos de superficie, erosionaron las rocas oscuras dejando los bordes rocosos claros. Tales marcas-color-claro-creadas por agua son bien conocidas aquí en la tierra. La hipotesis is particularmente interesante por como agua subterránea podria haber ayudado a sostener vida microbiótica en el mundo o planeta rojo. La imágen de arriba muestra las caracteristicas de superficie tan pequeñas como de un metro a través en la región Candor Carma de los enormes Valles Marineris en Marte.
