Scientists have combined NASA data and advanced imaging technology to study solar
The sun's magnetic influence extends tobillions of kilometers, far beyond the orbit of Pluto and the planets, it determines the movement of the stellar wind. This constant stream of solar material transports the Sun's magnetic field into space, where it forms the environment around the Earth and other objects.
Changes in the solar wind can createthe effects of space weather, which affect not only the planets, but also the people and missions that are now traveling throughout the solar system. The new work suggests that relatively small, previously unexplored features near the Sun's surface may play a decisive role in the nature of the solar wind.
In particular, we are talking about the “feathers” that make up the solar plumes.
This shows the importance of small-scale structures and processes that occur on the Sun.

The solar wind depends on unstable magnetic fields: the surface of the Sun is covered with loops and combinations of magnetic fields.
Using high resolution surveillance systems,The team found that plumes (carriers of solar material that affect the wind) are actually made up of much smaller strands of material, which they call plume. While the entire plume extends for about 112, 6 thousand km. in SDO images, each plume filament is only a few thousand miles wide, ranging from 3,700 km to 7,200 km.
This suggests that plumes are not structural features of the Sun, but rather the building blocks from which plumes are made.
Also, scientists found that the "feathers" moveindividually, each by itself. Scientists believe their individual behavior may be the main factor behind changes in the solar wind.
