Presented by Connie Orbach


Earmarked for 2024, the European- Extremely Large Telescope will be the biggest telescope in the world. The primary mirror is 39 metres across and capable of collecting as much light at once as all the other telescopes that mankind has ever built put together. The University of Oxford have been awarded the contract to build the telescope's new spectrograph, an instrument called HARMONI. Connie Orbach spoke to HARMONI'S principal investigator Niranjan Thatte to find out what it will do.
