NASA 's Parker Solar Probe is the fastest human-made object in the solar system.

Its instruments detected reversals in the direction of the sun's magnetic fields during its first brushes past the sun.

The corona is hundreds of times hotter than its "surface" than its photosphere, which is millions of miles closer to the Sun 's core.
