Physically, we understand what’s happening in terms of magnetism. These can be described as plumes or fountains, appearing as though there are threads connecting different regions of the Sun, and these bright plumes trace out those thread lines.
What you can see, just beyond the Sun’s photosphere, are loop-like structures that are glowing with hot, plasma-rich streams of matter. A large CME or solar flare could create a new type of natural disaster: a 'Flaremageddon' scenario. When these loops 'break' in just the right way, they can emit coronal mass ejections, which have the potential to impact Earth. satellite here in 2005, follow the path of the magnetic field on the Sun. Solar coronal loops, such as those observed by NASA's Transition Region And Coronal Explorer (TRACE). Instead, these threads are most similar to the traced lines we've seen in a completely different realm: close to the surface of the Sun. These thread-like features may seem unusual, but very similar structures have been observed in space before, although not in galactic environments like this. This tells us that something is likely happening between the stars - in the interstellar space separating them - that's being elongated into thread-like features over enormous distance scales: around ~20 light-years across, typically. Unlike in the X-ray portion of the spectrum, the radio signals appear to trace out filament-like shapes that appear to serve as bridges, connecting the various X-ray emitting regions to one another or at least appearing to be emitted from the brightest X-ray regions. Above is the same exact region of space, except instead of being imaged in X-rays from space, it’s been imaged in radio wavelengths from the ground: by the MeerKAT array of radio telescopes. One of the ways we gain important information about the Universe is by looking not just in one set of wavelength bands, like the X-ray, but in disparate ones.
