![]() Solar Orbiter is a space mission of international collaboration between ESA and NASA. The observations obtained with Metis aboard the Solar Orbiter ESA-NASA observatory will enable us to diagnose, with unprecedented temporal coverage and spatial. ![]() The Metis instrument is an inverted-occultation coronagraph part of the Solar Orbiter payload. All images show the two bright equatorial streamers and fainter polar regions that are characteristic of the solar corona during times of minimal magnetic activity. Abstract: Metis is the first solar coronagraph designed for a space mission capable of performing simultaneous imaging of the off-limb solar corona in both visible and UV light. A coronal imager for the Solar-Orbiter mission. Visible light images (580-640 nm) are shown in green and ultraviolet images (121.6 nm) are shown in red. The images shown here come from the instrument’s first light, which was obtained on, and from soon after Solar Orbiter’s first perihelion, on 21 June 2020. METIS - SOLAR ORBITER - DA DEPPO - ASI-INAF 2018-30-HH.0 (DFM.AD005.243) Thematic area Project area Structure responsible for the research project Project. The EUI is designed to cope with the strong constraints imposed by the Solar Orbiter mission characteristics. ![]() “This enables us to diagnose the structures and dynamics of the two major components of the solar corona: protons and electrons.” The EUI consists of three telescopes, the Full Sun Imager and two High Resolution Imagers, which are optimised to image in Lyman- and EUV (17.4 nm, 30.4 nm) to provide a coverage from chromosphere up to corona. ![]() “The Metis coronagraph measures simultaneously for the first time visible and ultraviolet emissions of the solar corona with unprecedented temporal coverage and spatial resolution,” says Marco Romoli, Metis Principal Investigator.

The Metis instrument on ESA’s Solar Orbiter blocks out the dazzling light from the solar surface, allowing the fainter outer atmosphere of the Sun, the corona, to be seen. ![]()
