ESA’s Solar Orbiter spacecraft has discovered a multitude of tiny jets of material escaping from the Sun’s outer atmosphere. Each jet lasts for between 20 and 100 seconds, and expels plasma at around 100 km/s. These jets could be the long-sought-after source of the ‘solar wind’.

A joint scientific team led by the Royal Observatory of Belgium (ROB) and the KU Leuven has found that high-frequency magnetic waves could play an essential role in keeping the Sun’s atmosphere at millions of degrees. This finding sheds a new light on the most intriguing solar mystery: what makes the Sun’s atmosphere hotter than its surface?

The EUI telescope on Solar Orbiter was able to catch the miniature version of solar flares and mass ejections. Thanks to sharp and fast imaging of the EUI telescope, researchers could observe magnetic reconnection taking place repeatedly on very small scales.

High-frequency sideways waves were detected for the first time using Europe's new solar observatory Solar Orbiter. These sideways waves are much more energetic than previously observed waves, and could play a role in heating the solar corona.

Solar Orbiter has spotted a ‘tube’ of cooler atmospheric gases snaking its way through the Sun’s magnetic field. The observation provides an intriguing new addition to the zoo of features revealed by the ESA-led Solar Orbiter mission, especially since the snake was a precursor to a much larger eruption.

On March 26, 2022, the Solar Orbiter satellite came closer to the Sun than ever before. A particularly exciting moment. The images of this closest approach -the perihelion-, taken by the Extreme Ultraviolet Imager (EUI) on board are will revolutionize solar physics!

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.
