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 Extreme Ultraviolet Imager aboard Solar Orbiter was able to observe magnetic loops that shake back and forth very quickly. Scientists suspect that it is these movements that heat the environment around the sun to millions of degrees Celsius.

On March 26, 2022, the Solar Orbiter satellite came closer to the Sun than ever before. The images of this closest approach taken by the Extreme Ultraviolet Imager on board 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.

On February 15, 2022, an immense cloud escaped from the sun. The space telescope EUI onboard the Solar Orbiter satellite could capture the solar cloud while it was hurled into space.

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.

Two Belgian adventurers collaborate with STCE scientists during an untypical triathlon in Greenland in April 2022: 600 km with skis and a pulka, 1000 km sea kayaking and 1 km vertical rock ascent. Nanok is a polar bear in the Inuit culture.

ESA made the first images and data of the instruments on board the spacecraft Solar Orbiter public. The telescope EUI, under Belgian lead, discovered campfires on the Sun.
