The DKIST, a 4m diffraction limited solar telescope on top of a mountain in hawaii
https://dkist.nso.edu/, comes online in science mode before the end of the year. It will be able to resolve tens of kilometer scale structures on the sun for the first time. There's still a lot left to be discovered on these small scales as the short timescale coherent radio emissions have indicated for decades. DKIST will give us our first images of whatever is making these very short radio burst... and whatever else is there we didn't predict.
