La imagen con mayor resolución de la historia de la astronomía muestra las entrañas de un núcleo galáctico

Desde 1974, la técnica conocida como interferometría de muy larga base (VLBI por su acrónimo en inglés) permite que múltiples radiotelescopios separados geográficamente trabajen al unísono, funcionando como un telescopio con un diámetro equivalente a la distancia máxima que los separa. Esta técnica ha aportando imágenes con una resolución antes inconcebible, más de mil veces mejor que las que obtiene el telescopio espacial Hubble.

The European Space Agency (ESA) will search for potentially dangerous objects from Calar Alto

NEOs (Near Earth Objects) are comets or asteroids which their orbits, possibly modified by gravitational pull of planets, lead them to regions near to the Earth orbit. Although possibilities of an impact against the Earth are very reduced, the scientific community are developing programs for detecting and studying such objects. Calar Alto Observatory (CAHA, MPG/CSIC) has signed an agreement with European Space Agency (ESA) for the exclusive use of one of its telescopes in ESA’s NEOs detection campaign.

Follow a Live Planet Hunt!

A unique outreach campaign has been launched that will allow the general public to follow scientists from around the globe as they search for an Earth-like exoplanet around the closest star to us, Proxima Centauri. The observing campaign will run from January to April 2016 and will be accompanied by blog posts and social media updates. No one knows what the outcome will be. In the months following the observations, the scientists will analyse the data and submit the results to a peer-reviewed journal.

History of Andromeda galaxy studied through stellar remains

The Andromeda galaxy (or M31) is the massive galaxy nearest to us, and it is an excellent laboratory to study the characteristics and the history of great galactic spirals such as our own Milky Way. An international group of researchers headed by the Institute of Astrophysics of Andalusia (IAA-CSIC) has used the Gran Telescopio Canarias to study a sample of planetary nebulae situated inside the two main substructures of M31 and has found that they could be the result of an interaction between Andromeda and its satellite galaxies.  

Researchers from the IAA and the UGR question results obtained heretofore in the study of pulsating stars

The movement of gas inside a star causes seismic waves which in turn cause irregularities on the star’s surface. These ‘earthquakes’ (or pulsations) produce periodic variations in the brightness of a star, and the study of those variations can reveal the physical structure and processes that take place inside.  A group of researchers examined the tools used to interpret those types of data and found that the methods which have been utilized for decades are not universally applicable.
