Julio 6, 2011: La nave espacial Dawn (Amanecer, en idioma español), de la NASA, se aproxima cada vez más a Vesta y, desde ahora hasta que esta nave propulsada por iones entre en órbita, a mediados del mes de julio, cada fotografía que se tome de este asteroide [...]

Composite of a Series of Images Taken From Space Aboard the Station
This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Space station hardware in the foreground includes the Mini-Research Module (MRM1, center) and a Russian Progress vehicle docked to the Pirs Docking Compartment (right). Expedition 31 Flight Engineer Don Pettit said of the photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 47 images photographed by the astronaut-monitored stationary camera were combined to create this composite. Image Credit: NASA

El esquema es parecido a nuestro Sistema Solar. El nuevo sistema es valioso porque, además, tiene un planeta parecido a la Tierra. Para los astrónomos inaugura una nueva etapa en la observación del Cosmos. Se descubrió un sistema planetario muy similar al nuestro. Tiene al menos siete planetas que orbitan alrededor de una estrella semejante [...]

La NASA es prácticamente la única organización en el mundo a cargo de rastrear los asteroides que amenazan la Tierra, pero carece de los fondos para cumplir la tarea cabalmente, según un reporte federal estadounidense. La razón radica en que, pese a que el Congreso de Estados Unidos le asignó esta misión a la agencia [...]
