During its many close flybys, the Probe dipped beneath 15 solar radii (around 6.5 million miles) from the Sun’s surface and transisted a feature in the corona called a pseudostreamer. 2021 Solar physicists are still puzzled over how the corona hangs onto this amount of heat.īruce Dorminey, Forbes, 2 July 2022 Technically, this term referred not to one specific virus, but to the subfamily Orthocoronavirinae, which is distinguished by its members' resemblance to a solar corona.
