Our knowledge of the universe is growing, and astronomers need more and better techniques to analyse astronomical phenomena. Europe’s largest astronomy network will assist in this area. The EU-funded Opticon RadioNet Pilot (ORP) will develop seamless access to radio and optical facilities in an efficient, coordinated and future-looking programme. ORP will offer access to an unrivalled set of major and specialised observatories across Europe (and around the world) covering the optical, infrared, sub-mm and radio wavebands to open the way to new discoveries. According to the project, this will represent the largest and most comprehensive suite of facilities to be brought together and offered to the European scientific community through a single programme.
