The Extreme Ultraviolet Imager (EUI) is part of the remote sensing instrument package of the ESA/NASA Solar Orbiter mission. EUI aims at improving scientific understanding of the structure and dynamics of the solar atmosphere, globally as well as at high resolution, and from high solar latitude perspectives. EUI consists of 3 telescopes that are optimized to image in Lyman-α and EUV (17.4 nm, 30.4 nm) to provide a coverage from chromosphere up to corona.

First view of the solar poles with EUI
Thanks to a push from planet Venus earlier this year, the orbit of the Solar Orbiter spacecraft was tilted. A century ago mankind raced to explore the poles of the Earth, now Solar Orbiter made its way to the poles of the Sun. For the very first time the solar poles have been imaged!
