A magnificent plasma snake observed on the surface of the Sun

It’s a funny observation that the Solar Orbiter mission (ESA, NASA). September 5th. As the observation satellite approached our Sun. Like a serpent gliding over the surface of our star!

The researchers tell us that the snake in question is none other than a ” tube “ of cold plasma moving along a particularly long filament of the magnetic field of our Sun. Long and winding. Hence the changes in direction observed. All in the hotter plasma environment of our Star’s atmosphere. And at a speed all the same of some 170 kilometers per second.

The information useful to scientists is that this snake emerged from an active region which then produced a Solar eruption which ejected billions of tons of plasma into space. A coronal mass ejection (CME), as astronomers call them. One of the most intense events recorded so far by Solar Orbiter’s energetic particle detector, by the way. And, icing on the cake, the coronal mass ejection then swept away the NASA mission. Parker Solar Probe. Enough to collect even more data on the event.
