Stunning new sun images show our star's popcorn-like magnetic field structure

Some solar telescope images here :) I note this in the report, "All told, the telescope now allows scientists to capture features on the sun that are only 30 miles (50 kilometers) across, according to the statement. "

The angular resolution to see about 50 km on the Sun from a distance of 1 AU, ~ 70 mas or 0".07. That is some solar telescope.

It's hard to imagine that the average size of each of those granules -- the scale-like surface features -- are about the size of Texas.

I'm guessing their 50km resolution comes when they are observing at around 400nm wavelength (based on my simple diffraction limit equation), which would explain the range of resolutions given since IR is also an important band observed.
