Plenty. What looks like generic dots to us laymen are actually different types of stars. With more resolution, astronomers can more accurately categorize the different stars in the galaxy. The ratios of different stars tell us things about the universe. With better high resolution images recently we've also been able to see confirmation of Gravitational Lensing [0] which reveal superstructures in space-time that affect the images we see. (i.e. with lower resolution we might've assumed we're seeing multiple distinct stars, with better resolution we understand that it's the same) For example, we just discovered the first "Einstein Zig Zag". [1] Ultimately, understanding the gravitational structure of space-time is the key to understanding dark matter which is arguably the biggest mystery of the universe today (besides dark energy).
