After a coronal mass ejection (CM), a rotation of the sun -survived plasma, the whirlpool is captured on the video by the European Space Agency’s solar orbiter, and can provide important clues about how magnetic energy that drives solar wind and huge explosions on the Sun, how is it released.
Twirting was seen by wrapped streammer Solar orbiter On October 12, 2022. It lasted for more than three hours, spread to 2 million kilometers in length (1.3 million mi), transporting plasma and magnetic energy The Sun,
Solar orbiter used its metis instrument, which has a feature Corongraph To block the dazzle of the sun’s body, to allow the solar orbiter to see just the unconscious outer of the sun AtmosphereCalling corona, both visual and ultraviolet light. It is a sensible corona, which is full of streamters, which we can see from the earth during the total Solar eclipse,
Packed structures are first caught on camera in solar corona, but they have never been seen in such an extension or so long. How the streammer is now offering clues from solar physicists solar wind And CMES,

Researchers, led by Paolo Romano of the National Institute for Astrophysics at the astronomy physics observatory in Catenia in Italy, have studied twisting streams and have discovered it all the way for its origin in Lower Corona.
The picture they presented is: Depending on the corona, the magnetic energy is stored in the taut magnetic field lines. The corona is filled with holes, such as Swiss cheese, where the magnetic field lines are open – this, they extend into space rather than bending back to the surface of the sun (called photofare) in a closed loop.
The solar wind blows through these coronal holes. A phenomenon known as the interchange reconation occurs, which is magnetic re -combination between open and closed magnetic fields in the lower part of the corona (where the magnetic field lines break and then re -connect, release energy). The most powerful re -combination events can be free to produce enough energy Solar flares And explosion of magnetic filaments resulting from CME.
On a small scale, the interchange re -combines a continuous and global population of jets that inject energy into the corona and through the coronal holes. These jets activate magnetic waves in solar plasma, which are called alphwen waves, which in turn pushes the plasma and coronal holes through the coronal holes, in the process of removing the substance on the solar air blowing through those holes in the process.
So where does the twisting streamer come in playing? Solar orbiter and its partner in Crime, Based on NASA’s observations Parker Solar Investigation – Which becomes so close to the sun that to actually take a dip in the corona – solar physicists are convinced that the magnetic composition of a large -scale interchange re -combining the magnetic composition is as “twisted flux rope”.
A flux rope is a tube of magnetic energy that is torn into a solar filament, a lace or channel of plasma organized by closed magnetic fields. The interchange re -combining the filament and surrounding open magnetic field lines releases the energy that strengthens a CME, resulting in a powerful jet that bursts through solar corona and in space, draws plasma to make CME. This flux tube makes a bright center of a CME.
And it is exactly that solar orbiter saw: Twisting Flux Tube released a huge CME in space after a powerful interchange resonance event.

According to computer simulation, the twisting nature of the flux tube is a natural consequence of a long -term interchange resolution. Solar orbiter’s comments were detected more than Metis. The fleeing flux tube decreases with the tilt of twisting features in the tube, or the tilt is reduced with the height of the sun, indicating that the magnetic field lines are aligned more radially with the sun because they go out Solar systemMagnetic field disturbances by streamer can only be amplified because they move deep into space.
Romano’s team guesses that it can be a mess that makes Magnetic switchbackWhere the direction of the magnetic field in the solar air suddenly reverses the course before continuing further in a type of zig-zaging speed, as viewed by both the solar orbiter and parker solar probe.
For decades, the biggest secret of the sun – how solar corona is heated more than a million degrees Celsius, for example, and where energy comes to run solar wind and CME – there were closely secrets. Now that the solar orbiter and parker solar investigation is getting closer to the sun, because it is possible, the sun is leaving its biggest puzzle for a long time.
The academic research paper describing the comments of the twisting streamer’s solar orbiter was published on 26 March The astrophysical journal,
