Launch of Europe’s largest astronomy network

Institutional matters


  • Two astronomy networks are coming together to form Europe’s largest ground-based astronomy collaborative network: the ORP.


  • The ORP will provide scientists with access to a wide range of instruments, promote training for young astronomers, and open the way to new discoveries.


  • The CNRS will be responsible for coordinating the ORP, which is supported by €15 million of funding from the H2020 programme.

Until now, Europe has had two major collaborative networks for ground-based astronomy, one in the optical domain and the other in the radio-wave domain. OPTICON and RadioNet have now come together to form Europe’s largest ground-based astronomy collaborative network. Launched with funding to the tune of €15 million under the H2020 programme, the project aims to harmonise observational methods and tools, and provide access to a wider range of astronomy facilities. The CNRS will coordinate the project, together with the University of Cambridge and the Max-Planck Institute for Radio Astronomy. In France, the network involves three research institutions, three research laboratories, two French observatories, and five international partner infrastructures.

As our knowledge of the Universe advances, astronomers increasingly need a range of complementary techniques in order to analyse and understand astronomical phenomena.  As a result, the European Union has decided to bring together the optical and radio networks OPTICON and RadioNet, who have successfully served their respective communities over the past twenty years. 

With €15 million in funding from the H20201, the EU programme for research and innovation, the European astronomy community will now benefit from the formation of Europe’s largest ground-based astronomy network: the OPTICON-RadioNet PILOT (ORP), which brings together some twenty telescopes and telescope arrays.

The ORP network is intended to harmonise observational methods and tools for ground-based optical and radio astronomy instruments, and provide researchers with access to a wider range of facilities, building on the success and experience of the OPTICON and RadioNet networks.

The new programme will make it easier for the astronomy community to access these infrastructures, as well as provide training for new generations of astronomers.

According to the management team2, « it is very exciting to have this opportunity to further develop European integration in astronomy, and develop new scientific opportunities for astronomy research across Europe and globally. »

The ORP will in particular foster the development of the booming field of what is known as multi-messenger astronomy, which makes use of a wide range of wavelengths as well as gravitational waves, cosmic rays and neutrinos.  Removing barriers between communities by harmonising observation protocols and analysis methods in the optical and radio domains will enable astronomers to work better together when observing and monitoring transient and variable astronomical events.

Astronomers from 15 European countries, Australia and South Africa, as well as from 37 institutions, have already joined the ORP consortium. It will be coordinated by the CNRS, which runs and contributes to several optical and radio telescopes.

In France, the following organisations are members of the consortium:

  • three research institutions: the CNRS, the French national aerospace research centre ONERA, and the Institut d'Optique Graduate School;
  • three research laboratories: the Laboratoire Lagrange (CNRS/Observatoire de la Côte d’Azur/Université Côte d'Azur), the Laboratoire d'Astrophysique de Marseille (CNRS/Aix-Marseille Université/CNES) and the Laboratoire d'Études Spatiales et d'Instrumentation en Astrophysique (Observatoire de Paris - PSL/CNRS/Sorbonne Université/Université de Paris);
  • two astronomical telescopes in the visible :  T193 of Observatoire de Haute-Provence, and Telescope Bernard Lyot of Pic du Midi3;
  • five international partner infrastructures: the Canada-France-Hawaii Telescope; the Institut de Radioastronomie Millimétrique (IRAM) (CNRS/Max-Planck-Gesellschaft/Instituto Geográfico Nacional), with its 30-metre telescope in Spain and its NOEMA observatory located in the French Alps; the LOFAR radio telescope; the SKA observatory; and the Joint Institute for VLBI ERIC (JIVE) consortium.
