Poorly phrased. The most recent stars are on the edges. The inner stars were first, hence the “working outwards”.

When does "starting in the center" mean anything besides "starting in the center"?
The earth is not the center of the galaxy

I actually am not following what the ambiguity is - stars farther out from the center are younger, no?

Try: "the farther out [from the center] astronomers look"

Looking from Earth at the stars closer to the center of a galaxy, they are found to be older. Looking from Earth at the stars closer to the edge of a galaxy, they are found to be younger.
