The Grenoble Observatory for Sciences of the Universe (OSUG) (French: Observatoires des sciences de l'Univers de Grenoble) is an astronomical observatory in France that is attached to CNRS-INSU [1] and Grenoble Alpes University.[2]

OSUG engages in scientific studies related to all aspects of the universe, the earth and environmental systems. The OSUG federates 1100 personals in 6 research Units, 5 Associated Research Teams and 2 joint service units federated, mostly located on the Saint-Martin d'Hères Campus near Grenoble.

OSUG was created on 26 November by governmental decree n° 85-1243.[3]

Research fields and Observation services[edit]

OSUG federates six research units (ISTerre, IPAG, IGE, LEGI, LECA, Irstea Grenoble), five associated research teams (FAME/ESRF, CEN/CNRM, Environnements/PACTE, SigmaPhy/Gipsa-Lab, LAME/LIPhy) and two joint service units (UMS OSUG, SAJF).[4] OSUG engages in scientific studies in astrophysics, planetary science, geophysics, geology, climatology, hydrology, glaciology and ecology.

OSUG manages a number of key Observing systems, which contribute to national and international databases. Finally, OSUG, within the University of Grenoble, plays a major role in defining and running higher education programs and provides initial and continuing education in Earth Sciences, sciences of the Universe and environmental sciences.


In 2003, the OSUG created the planetary path of the Arboretum Robert Ruffier-Lanche on the university domain of Grenoble.

In 2010, at the request of the city of Grenoble, OSUG designed and illustrated a geological trail along the Saint-Laurent de la Bastille pedestrian climb.

The OSUG permanent exhibition, which highlights its geological collections and the scientific observations of the establishment since its beginnings, opened in 2016).[5]
