The researchers observed long, web-like structures that eject particles from the Sun into space. A group of researchers from Southwest Research Institute, NASA, and the Max Planck Institute for Solar System Research has found web-like plasma structures in the Sun's middle corona by using an innovat
structures in the Sun’s middle corona by using an innovative observation method of imaging the middle corona in ultraviolet wavelength. Their findings were recently published in the journal. The discovery could help improve our understanding of the origin and interactions of the solar wind with the rest of the solar system.
New study reveals long, web-like structures in Sun’s middle corona. Credit: Southwest Research Institute To find new ways to observe the Sun’s corona, Seaton suggested pointing a different instrument, the Solar Ultraviolet Imager on’s Geostationary Operational Environmental Satellites , at either side of the Sun instead of directly at it and making UV observations for a month. What Seaton and his colleagues saw were elongated, web-like plasma structures in the Sun’s middle corona. Interactions within these structures release stored magnetic energy propelling particles into space.
Seaton believes these observations could lead to more comprehensive insights and even more exciting discoveries from missions like PUNCH , a SwRI-led NASA mission that will image how the Sun’s outer corona becomes the solar wind.
