A group of researchers from Southwest Research Institute, NASA, and the Max Planck Institute for Solar System Research has actually discovered web-like plasma structures in the Suns middle corona by using an ingenious observation approach of imaging the middle corona in ultraviolet wavelength. The discovery could help improve our understanding of the origin and interactions of the solar wind with the rest of the solar system.
To find brand-new methods to observe the Suns corona, Seaton suggested pointing a different instrument, the Solar Ultraviolet Imager (SUVI) on NOAAs Geostationary Operational Environmental Satellites (GOES), at either side of the Sun instead of directly at it and making UV observations for a month.” Now that we can image the Suns middle corona, we can connect what PUNCH sees back to its origins and have a more complete view of how the solar wind connects with the rest of the solar system,” Seaton said.
As the solar wind evolves, it can drive area weather and impact things like power astronauts, satellites and grids,” stated SwRI Principal Scientist Dr. Dan Seaton, one of the authors of the study. “The origins of the solar wind itself and its structure remain rather strange.
To discover brand-new methods to observe the Suns corona, Seaton recommended pointing a various instrument, the Solar Ultraviolet Imager (SUVI) on NOAAs Geostationary Operational Environmental Satellites (GOES), 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 extended, web-like plasma structures in the Suns middle corona. Interactions within these structures release stored magnetic energy moving particles into space.
” No one had monitored what the Suns corona was carrying out in UV at this height for that quantity of time. We had no idea if it would work or what we would see,” he said. “The outcomes were extremely exciting. For the very first time, we have premium observations that completely join our observations of the Sun and the heliosphere as a single system.”
Seaton thinks these observations could cause more thorough insights and much more interesting discoveries from objectives like PUNCH (Polarimeter to Unify the Corona and Heliosphere), a SwRI-led NASA objective that will image how the Suns outer corona ends up being the solar wind.
” Now that we can image the Suns middle corona, we can connect what PUNCH sees back to its origins and have a more complete view of how the solar wind engages with the remainder of the planetary system,” Seaton stated. “Prior to these observations, really few individuals believed you could observe the middle corona to these ranges in UV. These studies have opened up a whole brand-new method to observing the corona on a large scale.”

A group of scientists from Southwest Research Institute, NASA, and limit Planck Institute for Solar System Research has actually found web-like plasma structures in the Suns middle corona by utilizing an ingenious observation approach of imaging the middle corona in ultraviolet wavelength. Their findings were recently published in the journal Nature Astronomy. The discovery might help improve our understanding of the origin and interactions of the solar wind with the remainder of the planetary system.
The National Oceanic and Atmospheric Administration have been observing the Suns corona utilizing the Large Angle and Spectrometric Coronagraph on the NASA and European Space Agency Solar and Heliospheric Observatory spacecraft given that 1995 to track space weather that might affect Earth. The LASCO instrument has a blind area that prevents observations of the middle solar corona, where the solar wind stems.
