An anomalous emission has been detected in the microwave region of the Perseus Molecular Cloud. This work extends the frequency range of the studies being carried out by the WMAP satellite and finds between 11 and 17 Ghz per emission, 10 times greater than can be explained by normal emission processes in the Milky Way. One possible and attractive explanation is the presence of fullerenes, the bipolar electric emission of which is compatible with the observations (Watson, Rebolo et al., 2005, ApJ 624, L28).

The galactic gradient of C has been determined for the first time using recombination lines in HII regions. Results from these lines are more reliable than those derived from the traditional collisional excitation lines, which are stronger but subject to variations of temperature in nebulae (Esteban et al., 2005, ApJ 618, 195). These results have made it possible to greatly limit the number of possible models for chemical evolution in the Milky Way.

The abundances of oxygen and iron in metal-poor stars have been determined through non-LTE radiative transfer simulations in three-dimensional (3D) hydrodynamical models of their atmospheres. The performing of this type of calculations required to develop first very efficient numerical methods and computer programs. Taking into account that the atmospheres of the stars are 3D systems and the impact of non-LTE effects leads to very significant changes in the derived chemical abundances. It has been concluded that the metalicity of some metal-poor stars could be significantly larger than

Using a gravitational lens, the first precise determination of the extinction curve from the optical to the far UV has been carried out in a galaxy outside the Local Group (a z=0,83). It has turned out to be approximately the same as that observed at the LMC and different from that of our galaxy. These studies reveal the properties of interstellar dust in distant galaxies (Mediavilla et al., 2005, ApJ 619, 749).

Hace ya más de dos vueltas alrededor del Sol que caosyciencia empezó su andadura en la comunicación científica. Por fortuna, algunos habitantes de la Tierra continúan pensando que vale la pena seguir recibiendo gratuitamente este pequeño mundo habitado por artículos, animaciones, imágenes y vídeos, en el cual se explica un poco de todo, con un cierto favoritismo reconocido por la Astrofísica, no en vano es una iniciativa del Instituto de Astrofísica de Canarias (IAC). En este período insignificante en la escala del Universo, el rozamiento de caosyciencia con su entorno ha demostrado que no
