The NOVA-OIR group is hosted by ASTRON in Dwingeloo and is specialised in the development of infrared opto-mechanical cryogenic systems.

The NOVA Optical Infrared Astronomical Instrumentation Group develops systems and subsystems for the most advanced optical and infrared telescopes in the world and in space. This includes all development stages: from generation of novel ideas and technologies, to the use of the latest standards in design and manufacturing, and ensuring top quality by rigorous integration and testing.

NOVA is a major supplier of scientific instruments for the European Southern Observatory (ESO) Very Large Telescope (VTL), with instruments like: MATISSE, SPHERE, X-shooter, VISIR, SINFONI, MIDI. Instruments for the Isaac Newton Group (ING) at La Palma include: Wyffos, WEAVE and HARPS3. Telescope developments include: Meerlicht and the BlackGEM telescope array at ESO La Silla. We also develop space instrumentation, of which the most notably is the Mid InfraRed Instrument MIRI for the James Webb Space Telescope (NASA ESA JWST).

Our focus for the coming period is to develop instruments for the Extremely Large Telescope (ESO ELT). This includes the thermal infrared instrument METIS, a global collaboration where NOVA is the Primary Investigator institute. Other developments are: MICADO, MOSAIC and EPICS. With these instruments at the ELT, NOVA tries to solve the riddles of the universe: investigate the formation of stars and galaxies, determine properties of dark matter and dark energy, and characterize atmospheres of exoplanets.

We are very proud of @mabrentjens who has won @UniLeiden's Teacher of the Year 2022 award!

Today, construction on the #SKA radio telescope officially started. Together with @CGI_Global, S[&]T, and @TriOpSys we are already developing important software components for processing the vast amounts of data the SKA telescope will produce.

Today was the official start of the construction of the @SKAO's #SKA radio telescope in Australia and South Africa. Together with #TOPIC, we are already working on the development of the central signal processor for the SKA Low frequency telescope.

Daily image of the week: LDV gets busy
The LTA hosts about 60 PB of data, making it the largest astronomical data collection to date and an invaluable resource for science. The LDV aims to make these data available to the community.
