TANGO workshop logoFirst meeting TANGO@INAF

Trieste Astronomical Observatory will host the first TANGO@INAF meeting, exploiting one of the major distributed control system developed in Europe. TANGO is an object oriented distributed control system using CORBA for synchronous and asynchronous communication and 0MQ for event based communication. TANGO has been adopted as framework for the development of the distributed archiving system NADIR on behalf of Italian Astronomical Archives (IA2) and it is under evaluation as common platform to be possibly adopted in several astronomical projects of international relevance.

Olimpiadi di astronomia 2014

Domenica 16 e lunedì 17 febbraio l’Osservatorio astronomico di Trieste organizza in città un’importante gara intellettuale per studenti dai 14 ai 17 anni. Si tratta della fase interregionale delle Olimpiadi italiane di astronomia, alla quale parteciperanno 36 ragazzi e ragazze selezionati nella fase preliminare, provenienti dal Triveneto, che si cimenteranno sulla risoluzione scritta di 5 problemi di astronomia generale in vista della promozione alla gara nazionale e alla eventuale partecipazione alle gare internazionali.
La gara scritta sarà ospitata dal liceo Carducci-Alighieri, lunedì pomeriggio. La gara sarà preceduta, domenica 16, da incontri con gli astronomi, assieme ai quali saranno fatte osservazioni ai telescopi e conversazioni sui temi caldi della recente ricerca astrofisica presso la Stazione osservativa di Basovizza. Lunedì mattina, l’Osservatorio accoglierà studenti e accompagnatori per una cerimonia di presentazione e premiazione cui si aggiungerà una conferenza del dott. G.Vladilo sui pianeti extrasolari.
Le Olimpiadi italiane di astronomia sono organizzate congiuntamente dall’Istituto nazionale di astrofisica, dalla Società astronomica italiana e dal Ministero dell’Istruzione. Per informazioni si può consultare il sito telematico locale o anche quello nazionale


CS Clash Barbara m1206Observations enable first measurement of Dark Matter pressure

The nature of Dark Matter is still unknown. According to the present cosmological model, Dark Matter represents approximately 25% of the mass-energy content of the Universe, whereas ordinary matter contributes only 5% to the total mass. Within errors, the measurement determined that Dark Matter is pressureless. This is an important cosmological result since time and processes of the evolution of the Large Scale Structure of the Universe drastically vary according to the value of pressure. In a field such as Cosmology, where theoretical assumptions are numerous,  the observational measure of DM pressure  supports the Dark Matter hypothesis. Some authors of the research are astrophysicists located in Trieste such as This e-mail address is being protected from spambots.

Physics worldThe Planck satellite in the list of the 10-ten physics results

The Planck space telescope and the related research was awarded a Physics World Top 10 Breakthrough of the Year 2013 out of a list of over 350 published in the journal Observatory's researchers expressed great satisfaction at the award to the research on Planck satellite and Planck data which has been carried out by a large number of astrophysicists for twenty years.

esa-gaia-spaceprobeThe space mission of the GAIA Observatory started


The GAIA satellite of the European Space Agency was successfully launched on 19th December at 10:12 from Europe's Spaceport in Kourou, French Guiana. GAIA will survey with great accuracy the position of about one billion stars to make a three-dimensional map of our Galaxy and  to study its origin and evolution.

 Italy is strongly involved in the mission with the participation of eight Institutes of the National Institute for Astrophysics (INAF).

Planck: lights have been switched off but the party goes on

The satellite which has produced the most detailed map of the child Universe has been completely switched off. The collected information will require years of work to be fully exploited.

330marghe2Good bye Margherita!

The death of Margherita Hack left deep emptiness, both moral and human, in all of us at the Astronomical Observatory of Trieste. Margherita was director of the Observatory from 1964 to 1987. In the course of her long directorship she took up the reins of Astronomical Research in Trieste and transformed a small provincial Observatory into a modern International Research Institute. This was possible because her personality was a unique union of overflowing passion for research, great manager skills and steady character.

In remembrance of Margherita Hack by Stefano Borgani, Observatory`s director (italian)
