The Extremely Large Telescope

UK involvement in the ELT

ELT Instruments

The UK, via STFC, is funding R&D into future instruments for the ELT, ensuring that UK astronomers will be well-placed to benefit from the scientific discoveries that the telescope will deliver in the 2020s and beyond.

Three instruments are now under construction:

The UK is leading the HARMONI project (PI: Prof. Niranjan Thatte, University of Oxford) and the spectrograph work-package in METIS.

ESO's Instrumentation Roadmap lays out the plans for future instruments. As part of a coordinated programme to ensure the maximum science return, the UK is supporting R&D toward instruments beyond this first batch. The UK is participating in Phase A studies of future MOS (MOSAIC) and HIRES instruments (ESO release), and in long-term plans toward a planet-finding instrument called EPICS. The UK is also a major partner in the CANARY pathfinder experiment for laser guide star, multi-object adaptive optics (MOAO), which uses the 4.2m William Herschel Telescope in La Palma.
