<ul data-eligibleForWebStory="false">A new adaptive optic technique has provided detailed images of the sun's corona, which is usually difficult to observe due to its faintness.The images, captured at the Big Bear Solar Observatory, show plasma from solar prominences and coronal rain with unprecedented detail.Over 2,200 adjustments per second were made to the telescope's mirror to counter atmospheric distortions and improve resolution to 63 kilometers.There are plans to implement this technology on the 4-meter Daniel K. Inouye Solar Telescope for even finer imagery of the sun's corona.
