Entendemos la astronomía como un área en que la percepción visual cobra gran importancia y los astrónomos como científicos con gran agudeza visual. Veremos que esto no es así y que los avences teóricos y observacionales de la astronomía se han producido cuando hemos dejado de atender tanto a lo que nuestros ojos nos muestran.

Quasars are the most luminous stable sources in the Universe. They are currently
observed out to redshift z ~ 7 when the Universe was less than one tenth of its
present age. Since their discovery 50 years ago astronomers have dreamed of using

Los responsables de la misión han proyectado el viaje de Rosetta hacia el cometa de tal manera que el encuentro con el cometa 67P se produzca cuando este se sitúe a unos 675 millones de kilómetros del Sol.
The origin of the main excitation mechanisms in LINER
(Low Ionization Emission Line Region) nuclei are
still controversial, with nonstellar photoionization,

We have developed a reliable powerful method to measure the atmospheric column of
water vapour (PWV) down to very low levels.
For this purpose we use and off-the-shelf cheap spectrometer to measure the
equivalent width of the H2O bands at 940nm.

In this talk we will perform a review of the basic principles of the optical/near-infrared interferometry and of the current European facilities to use this observational technique. Particularly, we will describe the interferometric observables used at near-infrared wavelengths.

El Sol, y el Sistema Solar con él, se formó en algún lugar de la Vía Láctea hace cuatro mil quinientos millones de años. Desde entonces se inició un gran viaje a través de la Galaxia que nos ha ido separando más y más del entorno en el que se formó el Sol.

Outflows generated by protostars heavily affect the kinematics
and chemistry of the hosting molecular cloud due to strong shocks. These
shocks heat and compress the ambient dense gas switching on a complex
chemistry that leads to an enhancement of the abundance of several

¿Cómo sabemos la distancia al Sol? ¿Cómo conocemos la distancia a los planetas?, ¿y a las estrellas? El ser humano ha desarrollado diversos métodos y herramientas para medir la distancia a los cuerpos celestes. Una especie de juego de muñecas rusas en el que cada método está basado y calibrado en función de los resultados del anterior.

Planetary nebulae (PN) are one of the final phases in the evolution of
low and intermediate mass stars (<8 Msun). They display a great variety
of shapes, although in their previous phases (Asymptotic giant branch

The science performed in Astronomy is digital science, from observing proposals to final publication, including data and software used: each of the elements and actions involved in the scientific output could be recorded in electronic form.
