"Journey towards the Sun: how modern space missions are revolutionising solar physics"

Abstract: Burst of x-rays and mass ejection events from our closest star, the Sun, pose significant risk to our increasingly technology dependent society. Strong “space weather” events can damage national power grids, degrade our ability to communicate (by damaging satellites and blocking radio signals), induce currents along railway tracks, and irradiate airline crew and astronauts alike. Therefore, we need to develop better models to understand and forecast the Sun’s activity. Over the past five years, both NASA and ESA have launched missions to better understand the Sun. NASA’s Parker Solar Probe is making measurements from closer to the Sun than any other man-made object (at around a tenth of the Sun-Earth distance) and ESA’s Solar Orbiter is moving out of the orbital plane of the planets to make the first images of the Sun’s rotational poles. I propose to discuss recent advances in modelling the Sun and space weather, showing results from Parker Solar Probe and Solar Orbiter, putting these spacecrafts in context with 3D visualizations. After this, I will lead a hands-on demonstration showing the students how to use publicly available resources to monitor the Sun’s activity.
