University of Central Lancashire (UCLan) and NASA’s Marshall Space Flight Center researchers have revealed the highest-ever resolution images of the sun’s atmosphere. They were captured by NASA’s High-Resolution Coronal Imager (Hi-C) telescope, which was carried into space on a sub-orbital rocket flight. This high-powered telescope can identify structures in the sun’s atmosphere as small as 7km in size, or about 0.01% of its total size.

This same international team of researchers are now planning to launch the Hi-C rocket mission for a second time, overlapping their observations with two sun-observing spacecraft currently gathering further data: NASA’s Parker Solar Probe and ESA’s Solar Orbiter (SolO). Each of these strands are reportedly up to 1.8million degrees Fahrenheit (999982.°C), but the cause of them is still unknown.

Think of it like this: if you are watching a football match on television in standard definition, the football pitch looks green and uniform. Watch the same game in ultra-HD and the individual blades of grass can jump out at you – and that’s what we’re able to see with the Hi-C images. We are catching sight of the constituent parts that make up the atmosphere of the star,” said University of Central Lancashire scientists.
