NASA’s Parker Solar Investigation recorded an unprecedented plasma explosion in the corona of the sun, with a jet of the particles that exploding towards the surface of the star. This rare incident produced a sanward jet of plasma and accelerated the protons of about 1,000 times the expected energy. The unique convenience point of the parker between the incident and the sun allowed the jet return to a magnetic reconstruction site. In such events, twisted solar magnetic field lines snap and reel, explosively stored magnetic energy convert to rapidly growing plasma. These direct observations shed new lights on how magnetic re -combinations give strength to solar air and can improve the weather forecast.
Sanward plasma jet and magnetic re -combination
May 2025 Astrophysical Journal letters reported new reconnational findings paperAs Parker crossed the Sun’s Heliosferic current sheet (an uncontrolled border where solar magnetic field flip), it flew directly through the exhaust of a re -combination phenomenon. In a period of four hours at the end of 2022, the investigation has measured a sanward-pointing plasma jet and activated the stranded protons of about 1,000 times that could supply the local magnetic field. These measurements clearly tied the origin of particles by combining magnetic re -combining.
Magnetic recreation is the process in which magnetic field lines break and re -connect, convert magnetic energy into the motal energy of the particles charged in various natural and controlled environments, including terrestrial and planetary magnetosphere, solar and stellar flaings and fusion devices.
Implications for space weather and future research
It is important to understand these procedures for the forecast of space season. Acute solar activity and stable solar wind You can take away the atmosphere of the planets (as it was on Mars) and can trigger geomagnetic storms on the earth. Such storm power grids can damage the disadvantages satellites and disrupt GP and radio communication.
For example, May 2024 Solar storms disrupted GPS-directed farming equipment, causing an estimated $ 500 million. Because the magnetic field of the Sun is so huge and complicated, the computer model should simplify it; The Parker’s in-Seetu measurements help to refine these models.
