Paragraph 2
The Parker Solar Probe is named after the
Dr Eugene Parker. He spent most of his
studying the Sun and its solar
. He wanted to know why the flares, which shoot off from the Sun's
, are hotter than the surface. This is known as the "coronal
problem". It is a long-standing
for scientists. The temperature at the Sun's surface is around 4,100ºC; while the temperature of the corona's flares can reach 1.1 million
Celsius. Scientists also hope to find out how solar
originate. NASA said Parker (the probe) has faced
heat on its record-breaking fly-by. Temperatures reached a scorching 980 degrees
.
