A Xunta de Galicia pon por primeira vez a disposición dos cidadáns un banco de 10.000 fotografías aéreas da costa galega

El idioma Gallego se entiende bastante bien.
Santiago, 27 de agosto de 2010.- Por primeira vez, a Xunta de Galicia vén de poñer a disposición de todos os cidadáns un banco de case 10.000 fotos actualizadas da costa galega. Estas fotografías aéreas foron empregadas nos estudos dentro do Plan de Ordenación do Litoral e tanto as imaxes como toda a información pode consultarse na web do Plan de Ordenación do Litoral (www.xunta.es/litoral, apartado descargables)…

Trátase dun banco de imaxes aéreas en ángulo oblicuo cun alto valor informativo, divulgativo e paisaxístico, ademais de grande beleza. Esta colección elaborada a partir de diferentes voos que cobren a totalidade do costa galega conta ademais con compoñente espacial (coordenadas xeográficas) podendo ser incorporadas en bases de datos xeográficas e ser visualizadas en programas, como Google Earth.

A new image to add to the family photo album! The MESSENGER spacecraft is working its way to enter orbit around Mercury in March of 2011, and while wending its way, took this image of the Earth and Moon, visible in the lower left. When the image was taken in May 2010, MESSENGER was 183 million kilometers (114 million miles) away from Earth. For context, the average separation between the Earth and the Sun is about 150 million kilometers (93 million miles). It’s a thought provoking image, like other Earth-Moon photos — Fraser put together a gallery of Earth-Moon images from other worlds, and this one will have to be added. But this image was taken not just for the aesthetics.

This image was taken as part of MESSENGER’s campaign to search for vulcanoids, small rocky objects hypothesized to exist in orbits between Mercury and the Sun. Though no vulcanoids have yet been detected, the MESSENGER spacecraft is in a unique position to look for smaller and fainter vulcanoids than has ever before been possible. MESSENGER’s vulcanoid searches occur near perihelion passages, when the spacecraft’s orbit brings it closest to the Sun. August 17, 2010 was another such perihelion, so if MESSENGER was successful in finding any tiny asteroids lurking close to the Sun, we may hear about it soon.
