The corona runs considerably hotter compared to the photosphere, hitting temperatures of over 1,000,000 levels Fahrenheit. How the corona will get so sizzling continues to be a scientific thriller, which can be partly why NASA launched its Parker Photo voltaic Probe, the speediest spacecraft ever designed, and the very first ever despatched to the corona. (Examine more about the spacecraft that will “touch the Solar.”)
These curved and twisted features can access many thousands of kilometers in peak and width, and final anywhere from a couple of days to a few months.
