Solar winds, the streams of charged particles released by the sun, have long puzzled scientists. Despite numerous studies, the origin of these winds has remained a mystery. However, recent images captured by the Solar Orbiter’s Extreme Ultraviolet Imager (EUI) instrument may have provided some answers.
The Solar Orbiter, a joint mission by the European Space Agency (ESA) and NASA, has been instrumental in shedding light on the source of solar winds. In a groundbreaking paper published in Science, a team of researchers described their observations of large numbers of jets coming out of a dark region of the sun known as a “coronal hole.” These jets, dubbed “picoflare jets,” are significantly smaller and weaker than solar flares but still contain considerable energy.
The picoflare jets emit about one-trillionth the energy of the largest solar flares. They measure a few hundred kilometers in length and reach speeds of around 100 kilometers per second. Despite their relatively short duration of 20 to 100 seconds, these jets are believed to release enough high-temperature plasma to contribute significantly to our system’s solar winds.
While scientists have long known that coronal holes are source regions for solar winds, the mechanism by which plasma streams emerge from them has remained elusive. The discovery of these picoflare jets could finally provide the answer researchers have been seeking for years.

Lakshmi Pradeep Chitta, the primary author of the study from the Max Planck Institute for Solar System Research, highlighted the significance of their findings. He explained that the picoflare jets they observed are the smallest and weakest type of jets in the solar corona that have never been observed before. Despite their small size, the energy content of a single picoflare jet that lasts for about 1 minute is equivalent to the average power consumed by about 10,000 households in the UK over an entire year.
Chitta’s team plans to continue monitoring coronal holes and other potential sources of solar winds using the Solar Orbiter. Their observations not only have the potential to provide answers about plasma flows and their role in producing auroras on Earth but also offer insights into the mystery of why the sun’s corona or atmosphere is much hotter than its surface.
The Solar Orbiter’s mission goes beyond just unraveling the mysteries of solar winds. Its cutting-edge instruments and advanced imaging capabilities allow for a deeper understanding of the sun and its complex processes. By studying the sun up close, scientists hope to gain insights into its magnetic fields, solar eruptions, and other phenomena that have a significant impact on life on Earth.
In addition to the scientific advancements made possible by the Solar Orbiter, it is worth mentioning that its mission is a result of international collaboration. The partnership between ESA and NASA demonstrates the power and potential of global cooperation in advancing our knowledge of the universe.
