Performance Detective Parker NASA’s solar system is making great progress in solving an ancient mystery about… The sunThe spacecraft has provided new insights into why the sun’s outer atmosphere, known as the corona, is hotter than its surface.
Findings from the Parker Solar Probe
The Parker Solar Probe, the fastest man-made object, has completed 20 close passes of the Sun during these meetings, gathering data showing a sudden reversal of direction Magnetic fields For the Sun, which is called “revolution,” these revolutions could be crucial in understanding how the corona is heated.
Although the photosphere is closer to the core of the Sun, where nuclear fusion takes place, the temperature of the corona is hundreds of times higher showing that reversal is common in the solar wind near the Sun, however, it is not seen to have come from the corona itself, which eliminates one of the main theories about its role in heating the corona.
Finding heating devices
Scientists are investigating other possible explanations Temperature Corona rising The sun, this energy may be deposited in the corona, contributing to its heating.
The results of the Parker Solar Probe improve our understanding of the behavior of the Sun and have implications for forecastingSolar stormsThe probe’s mission, which began in 2018, continues to provide valuable data It will return to approach the sun on September 30, and will come closer on Christmas Eve year its dynamic processes.
