METIS Instrument Passes Design Milestone

5. června 2020

METIS, the powerful imager and spectrograph for ESO’s Extremely Large Telescope (ELT), has passed its Preliminary Design Review at ESO’s headquarters in Garching, Germany. METIS, short for Mid-infrared ELT Imager and Spectrograph, will make full use of the giant main mirror of the telescope to study a wide range of science topics, from objects in our Solar System to distant active galaxies. METIS will be extremely well suited to study the life cycle of stars, from infant stars and planet-forming discs to older stars near the end of their lifetime.

The ELT will be the largest optical to mid-infrared telescope on Earth when it starts operations towards the middle of this decade. With its 39-metre primary mirror and advanced adaptive-optics systems, it will have six times the resolution of the James Webb Space Telescope. METIS will take full advantage of this remarkable telescope and its adaptive optics to probe the structure and composition of objects with revolutionary precision.

Among others, METIS is expected to make large contributions to one of the most dynamic and exciting fields of astronomy for both scientists and the public, exoplanets. The instrument will be able to study the temperature, weather, and seasonal changes of the atmospheres of many giant exoplanets. Furthermore, METIS has the potential to directly detect terrestrial exoplanets around the nearest stars and, in favourable cases, investigate their atmospheric composition.

Now that the instrument has passed this Preliminary Design Review, the METIS consortium will continue to develop its design in further detail before construction on the instrument starts.
