El satélite ‘Kepler’ observa dos ‘Saturnos’ que orbitan una estrella similar al Sol a menos distancia que Mercurio Los sistemas planetarios que se han detectado hasta ahora son, en su inmensa mayoría, tan distintos del Sistema Solar que resulta difícil imaginarlos, tan difícil como fotografiarlos. El último observado con la técnica del tránsito (cuando el [...]

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

Astrónomos suizos han descubierto nueve planetas hasta ahora desconocidos fuera de nuestro Sistema Solar. La noticia podría ser una más de los numerosos anuncios de nuevos exoplanetas encontrados más allá de estos límites -ya se conocen 452, pero el hallazgo de estos mundos ha ayudado a conocer una extraña particularidad. Algunos de ellos -y otros [...]
Sorprendentes hallazgos continúan llegando desde el exterior del Sistema Solar. Si hace tan sólo unos días el telescopio Spitzer encontró indicios de un choque entre dos astros, en esta ocasión científicos británicos han descubierto un planeta que orbita en dirección contraria a la que se desplaza su estrella. En cada sistema planetario, la mayoría de [...]
Investigadores del IAC aprovechan un eclipse para observar nuestro planeta como se haría desde una estrella lejana Con un poco de suerte, en la próxima década se encontrará el primer planeta extrasolar con un parecido razonable a la Tierra. Entonces, los astrónomos estudiarán su atmósfera para tratar de averiguar de qué está compuesta e intentar [...]
