Researchers Reveal Highest-Ever Resolution Images Of The SunAdd to Lightbox Download
Newly released images of the Sun have revealed that its outer layer is filled with previously unseen, incredibly fine magnetic threads filled with extremely hot, million-degree plasma. The high-resolution observations have been analysed by researchers at UCLan alongside collaborators from NASA’s Marshall Space Flight Centre (MSFC) and will provide astronomers with a better understanding of how the Sun’s magnetised atmosphere exists, and what it is comprised of.
Until now, certain parts of the Sun’s atmosphere had appeared dark or mostly empty, but new images have revealed strands that are around 500km in width - roughly the distance between London and Belfast - with hot electrified gases flowing inside them.
The ultra-sharp images were taken by NASA’s High-Resolution Coronal Imager (or Hi-C for short), a unique astronomical telescope carried into space on a sub-orbital rocket flight. The telescope can pick out structures in the Sun’s atmosphere as small as 70km in size, or around 0.01% the size of the Sun, making these the highest resolution images ever taken of the Sun’s atmosphere.
