At this point, a lot of things would be pretty esoteric. Take a look at recent Nobel laureates and you'll see that they largely don't make much sense to the average person. So, you could do something along those lines. For instance:

A method of reducing sensor energy drain while increasing resolution

Producing a solid proof of objects smaller than previously observed.

Demonstration of transmission reception of detailed data from a neutron star farther than previously thought possible.

etc.
