This is an interesting one. At https://www.sciencedaily.com/releases/2023/11/231113192112.htm … in a study published in Nature Astronomy scientists have outlined their discovery of an aurora like display 40,000 km above a dark sun spot on the face of the Sun. The radio emissions show similarities with radio transmissions seen in planetary magnetospheres such as that of the Earth, Jupiter, and Saturn. This appears to offer solar scientists some input into the origin of solar radio bursts in other parts of the universe. Not just in our solar system. Therefore, it aids astrronmers in defining similar phenomena as seen on stars in other galaxies. For more info see https://doi.org/10.1038/s41550-023-02122-6 …
The lead author, Sijie Yu, says the long lasting polaroid radio burst emanating from a sun spot, was doing so for over a week. It may explain what is happening out in the universe, he added. Analysis suggests these are due to energetic electrons trapped within emerging magnetic fields. Sporadic flare activity in nearly active regioins seem to pump energetic electrons into magnetic field loops anchored at the sun spot. It is thousands of times stronger than aurora on the Earth. The team add, linking the behaviour of our Sun to other stars far beyond the solar system, could have implications for astro-physicists to rethink their current model of stellar magnetic activity.
However, over at https://www.livescience.com/space/black-holes/our-galaxys-monster-black-hole-is-spinning-at-top-speed-and-its-dragging-everything-along …. the concern is that the black hole at the heart of the Milky Way galaxy, the so called Sagittaurius A, is spinning so fast it is dragging anything near it along for the ride. It seems that theoretical theorists are keeping the boat steady – even if the elecron maganetic waves are lapping at its side. A classic case of some people immersed in their own discipline being completely unaware of what is happening outside that discipline.
