This is kind of what i wanted when i made a thread called Enriching the galaxy.
One of the reasons for that was that when i played Mass Effect 3 mini mining and scanning game with the Normandy SR2 there was a ton of planets in the galaxy and each one had a small or a long description about some ruin being found, or scientists discovering something, or that this particular gas giant is a an extra-solar capture, or binary stars, systems with different star sizes(because lets face it different colors is not enough).
Also information about planets and stars like rotation cycles, gravity, surface temperature core and atmospheric composition go along way to make a galaxy seem like an exiting place.
Comets and zipping around, and giant gass cloud formations acting as space terrain would also improve the feel of the galaxy.
A little picture i want to add.
