Parker Solar Probea NASA mission launched in 2018, has revealed hitherto unknown secrets of the solar wind. This stream of energized particles, emanating from the sun’s corona, or hot outer atmosphere, toward Earth, has long been a mystery. However, thanks to the probe, we now understand more about its origin and how its finer structures form near the photospherethe surface of the sun.

Practical Implications for Earth

The study of the solar wind has not only theoretical implications, but also practical ones, and of great importance for our daily life. Although it can sometimes result in the formation of beautiful auroras, this solar wind can affect the satellites Yet the electrical network Earth, disrupting our communication and power systems.

The Structure of the Solar Wind

Coronal holes, the dark regions in the sun’s corona, play a crucial role in generating the solar wind. The probe data revealed that these holes act as ‘showers’, emitting streams of charged particles. It is at these bright spots that the magnetic field enters and leaves the photosphere.

Fast Solar Wind Generation

The reconnection of magnetic fields within supergranulation cells on the solar surface appears to be the process that generates the fast solar wind. These supergranulation cells are large-scale convection zones on the sun’s surface, similar to bubbles in a boiling pot of water. The Parker Solar Probe detected energetic particles traveling at speeds well above the speed of the solar wind, leading the researchers to this conclusion.

Solar Maximum in 2025

Scientists anticipate that the sun will reach its solar maximum in July 2025. During this peak of solar activity, which occurs every 11 years, an increase in the occurrence of solar flares and changes in the visibility of auroras are expected. The Parker Solar Probe, thanks to its position and capabilities, is perfectly capable of observing these fascinating and dramatic solar events.

Finally, it is important to note that each discovery about our sun not only expands our knowledge of the universe, but also helps us to better prepare for phenomena that can have a direct impact on our daily lives. The data collected by the Parker Solar Probe offers us an invaluable resource for understanding and predicting solar behavior, and for ensuring the resilience and future of our technology systems.
