A concise survey of light scattering by small dust particles in the atmospheres and surface layers of various Solar System bodies, comets, the interplanetary medium, and in planetary rings is presented. Current issues and recent developments are emphasized.

Las dos estrellas mas brillantes de la LMC en este momento son dos VLA en estado de erupción. Radcliffe 127 (R127) había sido una estrella de tipo Ofpe antes de 1980.

Both a dense stellar cluster and streamers of gas and dust coexist within the central parsec of the Milky Way Galaxy, in the deep potential well of the 4 million MSun black hole at the position of the radio source SgrA*.

En esta charla pretendo dar una visión global de la misión Sunrise, de sus propósitos científicos y de su desarrollo tecnológico.

Asteroids that come close to the Earth´s orbit (near-Earth asteroids, or NEAs) are targets of different sample-return space missions, providing us with material from their surfaces.

I will present my personal list of the 25 most important and influential discoveries in astronomy of the 20th century. I will analyse the papers that reported these discoveries by the year they occurred, the age of the discoverers and the country where the people worked.

Black hole mass and Eddington ratio estimates for quasars are of fundamental interest to astrophysicists and cosmologists. Comparisons of high and low redshift quasar properties are of special interest.

I will present the PPAK Integral Field Spectroscopy (IFS) Nearby Galaxies Survey: PINGS, a 2-dimensional spectroscopic mosaicking of 17 nearby disk galaxies in the optical wavelength range.

I will present an astrometric catalogue of positions and proper motions derived from the "Carte du Ciel" plates, San Fernando zone, which has a mean epoch 1901.4 and a limiting magnitude V~15. Digitization has been made using a conventional flatbed scanner.

I will describe a new program at Mt John that aims to find Earth-mass planets orbiting either alpha Cen A or B, which are solar type stars in a well known binary. We are measuring precise radial velocities using the Hercules spectrograph, which I will describe.

It was noted soon after the discovery of the first quasars that some of them were surrounded by a nebulosity. Narrow-band imaging surveys and spectroscopic studies of quasars by Stockton et al. and Boroson et al.

En los últimos años se han lanzado dos misiones espaciales CoRoT (CNES, ESA) y Kepler (NASA) que presentan objetivos científicos. Por un lado, buscar exoplanetas, i.e.

This talk, which is intended for non-specialists and makes particular emphasis on astrophysical/cosmological implications, will review the underlying physical motivations for the suggestions that spacetime is noncommutative.

La Astronomía moderna no se puede concebir sin el trabajo realizado por todas aquellas mujeres que con su dedicación y amor a la ciencia nos han dejado su legado.

Attached to the 1.6-meter telescope of the Observatoire du Mont Mégantic in southern Québec, SpIOMM is an imaging Fourier transform spectrometer designed to obtain the visible range (350 – 850 nm) spectrum of every astronomical light source in a circular field of view of 12 arcminutes in diameter

The MAGIC-I telescope is currently the largest single-dish Imaging Atmospheric Cherenkov telescope in the world. A second telescope, MAGIC-II, will upgrade MAGIC-I in sensitivity, angular and spectral resolution from this year on.
