Astronomers discover “feathers” in the corona of the sun, today, Friday, January 22, 2021 6:16 in the morning
The sun’s magnetic field and associated solar winds form space weather in and around the solar system, and solar wind disturbances affect humans and space devices. The open areas in the sun’s magnetic field create coronal holes, which are dark spots of low intensity. Within a few days, some of these holes release fountains of solar material called the “tail” (column), which can be seen clearly in ultraviolet rays and monitored by the NASA Solar Dynamics Observatory (SDO).
Using this observatory and advanced image-processing technology, scientists were able to discover that this solar material is composed of fine filaments that they called “feathers”. If the size of this “tail” equals 100,000 kilometers, then the width of the thread ranges between 3-7 thousand kilometers. Head of the research team, Vadim Uritsky of the American Catholic University in Washington and Goddard Space Flight Center, says, “This demonstrates the importance of small structures and ongoing operations. In the sun, in understanding the solar wind system and the weather of space in general. ”It became clear to scientists that“ feathers ”are not just an element of the“ tail ”, but rather the basic building block of the“ tail, ”as its brightness is directly related to the number of“ feathers. ” Scientists also, that each “feather” vibrates automatically and independently, which allowed the scientists to assume that the behavior of these structures may be the cause of local disturbances to the solar wind.
