From Earth, we always look towards the Sun’s equator. This year, the ESA-led Solar Orbiter mission broke free of this ‘standard’ viewpoint by tilting its orbit to 17° – out of the ecliptic plane where the planets and all other Sun-watching spacecraft reside. Now for the first time ever, we can clearly see the Sun’s unexplored poles.
This image shows Solar Orbiter’s view of the Sun’s south pole on 23 March 2025. It was taken by the spacecraft’s Extreme Ultraviolet Imager (EUI) instrument, which captures the ultraviolet light sent out by the million-degree gas in the Sun’s outer atmosphere (the corona).

Solar Orbiter is a space mission of international collaboration between ESA and NASA. The Extreme Ultraviolet Imager (EUI) instrument is led by the Royal Observatory of Belgium (ROB).
