The powerful NSF Inouye Solar Telescope has just delivered absolutely mind-blowing observations of its first X-class solar flare.

On 8 August 2024, the telescope managed to capture one of the most powerful flares our Sun is capable of producing – at a remarkable resolution of just four Earths across. This level of detail reveals some of the finest structures we've ever seen associated with a solar flare, opening a new window into the Sun's most extreme eruptions .

"This is the first time the Inouye Solar Telescope has ever observed an X-class flare," says astronomer Cole Tamburri of the University of California Boulder. "These flares are among the most energetic events our star produces, and we were fortunate to catch this one under perfect observing conditions."
