Venus is covered by a dense layer of clouds which does not display any noteworthy characteristic. However, when looked in the ultraviolet wavelength, it presents conspicuous dark structures. The biggest one, which practically covers the entire planet, is shaped like a “Y” and it has been a mystery since its discovery more than half a century ago.

Dentro del programa de la asamblea trianual de la Unión Astronómica Internacional, que tendrá lugar en Hawaii el próximo mes de agosto y acogerá a miles de astrónomos, se celebrará una reunión dedicada al estudio de las explosiones de estrellas de alta masa, como las supernovas o las explosiones de rayos gamma (GRBs). La sesiones tendrán lugar del 11 al 13 de agosto y el plazo para la recepción de propuestas está abierto hasta el 18 de marzo.
Con motivo del día de Andalucía, en el 35 aniversario del Estatuto de Autonomía, se celebró ayer la entrega la entrega de las Banderas de Andalucía, galardones que la Comunidad autónoma otorga como reconocimiento a la labor y trayectoria de andaluces que destacan en sus campos profesionales.
La entrega de galardones se llevó a cabo en un acto celebrado en el Parque de las Ciencias, presidido por la consejera de Igualdad, Salud y Bienestar Social, María José Sánchez.
The scientific journal Astrophysical Journal Letters is publishing a study, led by researchers at the Astrophysical Institute of the Canaries (IAC), which has been the subject of a report in the journal Nature. It the study Jupiter is presented as an ideal laboratory for research into exoplanets which are similar. Jupiter, the largest planet in the Solar System, has large satellites around it. The study has used the largest of the satellites, which is the biggest satellite in the Solar System, Ganymede, as a mirror to analyze the atmosphere of the planet.
The magnetic field that covers the Sun and determines its behavior –the eleven year cycles no less than such conspicuous phenomena as solar spots and solar storms– also has another side to it: a magnetic web that covers the entire surface of the Sun at rest and whose net magnetic flow is greater than that of the active areas. A study led by the Institute of Astrophysics of Andalusia (IAA-CSIC) has revealed where the flow that feeds this web comes from.

El campo magnético rige el comportamiento del Sol y es el responsable de su ciclo de once años y de fenómenos tan llamativos como las manchas o las tormentas solares. Pero también muestra otra faceta, una red magnética que cubre toda la superficie del Sol en calma y cuyo flujo magnético total supera al de las zonas activas. Una investigación encabezada por el Instituto de Astrofísica de Andalucía (IAA-CSIC) ha revelado de dónde procede el flujo que alimenta esa red.
In March 2012 amateur astronomers in different corners of the world gathered images of a plume emerging at dawn on the edge of the disc of Mars. Even though spacecraft orbiting Mars have on numerous occasions observed thin cloud layers on the limb, the maximum altitude of these layers has never exceeded 100 km. This bulge, by contrast, was over 200 km high and could be seen over about ten days, but only during the Martian dawn.
