About this episode

This episode discusses new findings from Solar Orbiter regarding the Sun's magnetic boundary and its implications for space weather models.

Using data from Solar Orbiter, researchers have taken a closer look than ever before at the heliospheric current sheet, a vast magnetic boundary surrounding the Sun. They discovered that changes in ion composition closely follow shifts in magnetic polarity, revealing a more complex interaction between the solar corona and solar wind. The findings could improve space weather models and our understanding of how the Sun accelerates charged particles into space. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
