INAF – Observatory of Astrophysics and Space Science of Bologna
The INAF Observatory of Astrophysics and Space Science of Bologna (Osservatorio di Astrofisica e Scienza dello Spazio di Bologna, OAS) is one of the largest and most prolific astrophysical research institutes in Italy, with roots going back to the historic Specola astronomica di Bologna founded in 1714. Located at the Villa Mellini di Loiano and its Bologna campus, OAS Bologna conducts forefront research in cosmology, high-energy astrophysics, exoplanet science and space missions, hosting hundreds of researchers and contributing to major European and international astronomical projects.

Overview
OAS Bologna is among the most productive astrophysical research centres in Europe, with a staff of over 200 researchers and technical personnel working across an exceptionally broad range of topics: cosmology and large-scale structure, galaxy formation and evolution, high-energy astrophysics (X-ray and gamma-ray), solar physics, astrochemistry, and space science instrumentation. The institute maintains the historic Loiano Astronomical Station with two active telescopes on the Apennine ridge south of Bologna, and its Bologna campus hosts advanced computing infrastructure supporting major space missions including contributions to ESA’s Euclid and Gaia projects.
History
Bologna has one of the oldest continuous astronomical traditions in Europe: the university’s Specola astronomica dates to 1714, making it among the earliest purpose-built astronomical observatories on the continent. The modern observatory lineage descends from the Osservatorio Astronomico di Bologna, established at the Villa Mellini estate in the hills of San Luca, which in the 20th century developed into a research-oriented astrophysics centre. In 1994 a separate Institute of Space Astrophysics (IASF) was created in Bologna focused on high-energy space astronomy, and in 2016 the two INAF structures were merged to create the current OAS Bologna, one of INAF’s largest institutes. The Loiano Astronomical Station, operational since the 1970s, continues to host the 152-cm Cassini telescope and the 60-cm Zeiss refractor for observational programmes.
What you see
The Bologna campus occupies a modern research building in the university district, housing offices, laboratories, data centres and a library specialising in astrophysics. At the Loiano Astronomical Station (approximately 35 km south of Bologna on the Apennine crest at 785 m altitude), visitors can see the white domes of the Cassini 152-cm reflector and the smaller Zeiss telescope against the forested hillsides of the Apennines. The station occasionally opens for public observing evenings and guided visits. The historic Specola tower remains visible in the Bologna city centre at the Palazzo Poggi, now a university museum.
Cultural significance
OAS Bologna embodies Bologna’s centuries-long tradition as a centre of scientific learning, rooted in one of the world’s oldest universities (founded c.1088) and manifested today in internationally competitive research contributions to the understanding of the cosmos. The institute’s work on cosmological large-scale structure, galaxy evolution and space instrumentation places Bologna firmly within the global network of institutions advancing humanity’s knowledge of the universe.

Getting there
The Bologna campus (Via Gobetti) is in the university district of Bologna, approximately 3 km north of Bologna Centrale railway station. City bus lines 25 and 27 stop nearby. Bologna Centrale is a major rail hub on the Milan–Rome and Venice–Florence high-speed lines. For the Loiano station, a car is required: take the SS65 della Futa south from Bologna approximately 35 km; the observatory road is signposted from Loiano village.
