a probe Parker Solar Probe (PSP) was able to gather detailed information regarding the solar wind structure, considered complex and responsible for transporting charged particles to the Solar System via openings in the solar corona. The results were analyzed by physicists Stuart Bale of the University of California, Berkeley, and James Drake of the University of Maryland.
This was all possible following the equipment reached an impressive distance of 8.5 million kilometers from the Sun in November 2021. It is worth remembering that the item’s journey began in 2018, following a development process that lasted more than 60 years.
As it approached the Sun, the PSP spacecraft encountered a coronal hole, which data showed resembled a shower. In addition, jets kept emerging at evenly spaced intervals from places where magnetic field lines narrow and expand away from the star’s surface.
In order to understand how winds arise, there is a mechanism that involves the reconnection of open and closed magnetic fields, something known as interchange reconnection. Likewise, another explanation is the acceleration of particles that occurs due to electromagnetic waves in coronal holes.
Through the analysis of the information collected by the PSP, it was possible to notice particles traveling at high speeds, something that is in line with the first explanation cited. Drake finally commented on the importance of this type of study for the Earth in practical matters:
