Neptune from Voyager 2. Color is from images with CH4JS, green and orange filter.
Shadows of three moons are visible. Second image is with possible interpretation. -------------------- |

The Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS), is a new instrument designed by Princeton to observe exoplanets, and works in conjunction with the Subaru Telescope in Hawaii. It has also returned a quite astonishing image of Neptune:

That's a great image; I've seen an even sharper image of Ganymede, which I won't link because it's off topic. And the instrument isn't designed for Neptune but, in a nutshell, instruments with resolutions better than 0.01 arc seconds /pixel are now becoming available, which means that we can track features hundreds of km in size, maybe even under 100 km. That means that Neptune could be tracked almost continuously for the ~3/4 of the year when it's not lost in daylight. And echo that for Uranus, with 50% better detail. Indeed, with a lowly 6-inch telescope, I've imaged clouds in visible light on Uranus, which, owing to the seasons, Voyager 2 didn't even accomplish! It's a new era for the outer planets.
