The Parker Solar Probe is after the astrophysicist Dr Eugene Parker. He most of his life studying the Sun and its solar flares. He wanted to know why the flares, which off from the Sun's surface, are hotter than the surface. This is as the "coronal heating problem". It is a long-standing mystery for scientists. The temperature at the Sun's surface is around 4,100ºC; while the temperature of the corona's flares can 1.1 million degrees Celsius. Scientists also to out how solar winds . NASA said Parker (the probe) has extreme heat on its record-breaking fly-by. Temperatures a scorching 980 degrees Celsius.
