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’.

Heat waves on the Sun (EN-FR-NL)

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?
