ACTIVITAT CIENTÍFICA

L'activitat científica a la qual es dedica l'Observatori Esteve Duran, l'observació sistemàtica, és única a Catalunya i fins i tot a nivell internacional, són molt pocs els centres d'investigació astronòmica dedicats a aquesta important tasca. 

Sistema binari descobert a l'Observatori Esteve Duran. La figura és una visualització artística imaginaria d'aquest sistema estel·lar

Des de la seva posada en funcionament el març de 1996, el treball d'investigació de l'Observatori Esteve Duran ha aportat el descobriment de noves estrelles variables, de les quals ja s'han fet conèixer els resultats a la comunitat astronòmica internacional. Solament aquest fet constitueix tot un punt decisiu dins la història de l'observació astronòmica de Catalunya.
