getting into corona
The corona, which is much hotter than the visible surface of the Sun, is a dynamic region where plasma and magnetic fields are constantly changing. NASA's Parker Solar Probe passed the Alfvén critical surface in 2021, becoming the first spacecraft to take particle and magnetic field measurements from inside the corona.
What do the closest images show?
The closest images released by NASA in 2025 showed structures in the solar wind and the collision of multiple coronal mass ejections in high resolution. The images alone do not explain the entire heating mechanism; It is evaluated together with plasma, particle and magnetic field measurements.
Why is it important for the Earth?
Solar wind and coronal mass ejections can affect satellites, communications and power grids. A better understanding of source mechanisms could improve space weather models. Parker's closest flyby, approximately 6.1 million kilometers away, provides a unique laboratory for these models.
