EUI

A Patchwork Image of the Sun

On 7 March, 2022, the high-resolution telescope of the Extreme Ultraviolet Imager (EUI) onboard the Solar Orbiter spacecraft made a mosaic image of the solar disk. Over a period of more than 4 hours, the satellite aimed at different positions each time capturing a small square of the Sun at very high resolution. These images were then stitched together like a patchwork. The result was an extremely detailed image of the entire Sun.

Solar Orbiter returns to Earth for a last goodbye

On 27 November 2021, the Solar Orbiter spacecraft returns from its voyages in deep space, and will pass at only a few hundred kilometers above the Earth's surface. This manoeuvre is needed to get Solar Orbiter in a new orbit to go yet closer to the Sun. During this flyby, Solar Orbiter unfortunately needs to cross the clouds of space junk that surround Earth, making it a risky visit to our planet.

EUI - First Light 1 year

The 3 telescopes of the Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter opened their doors on May 12, 2020 to photograph the Sun. This is exactly 1 year ago. This ‘First Light’ was a crucial step to get the EUI telescopes up and running and pave the path to research.

Kees de Jager 100!

In honour of the 100th Birthday of Kees de Jager, prominent Dutch astronomer and one of our favorite solar physicists, the EUI instrument onboard Solar Orbiter took a pair of images in two different wavelengths. The images were taken in the very early morning of April 29, at 00:19:21 and 00:20:21 CEST representing the years 1921 and 2021.

Press release: Launch of Solar Orbiter

10 February 2020 - NASA will launch the Solar Orbiter spacecraft from Cape Canaveral, with 10 scientific instruments on board, including the space telescope Extreme Ultraviolet Imager (EUI). Solar Orbiter is an ESA mission, with an important contribution from NASA, which will study the Sun from close up. The EUI instrument was built by a European consortium under the leadership of the Centre Spatial de Liège. After the launch, the Royal Observatory of Belgium will manage the observations and coordinate the analysis of its unique solar images.

Press release: “Last Chance to View Solar Orbiter. EUI and Solar Orbiter ready for launch!”

Brussels, 18 October 2019 – Ever closer to the Sun! The instrument EUI (Extreme Ultraviolet Imager) is integrated into the Solar Orbiter satellite to be launched towards the Sun in February 2020. Today, Solar Orbiter can be seen for the last time before being shipped to Cape Canaveral, the launch site.
