What you want is Space Engine [en.spaceengine.org/]. Also a sandbox. Allows you to fly from star to star, galaxy to galaxy, with billions of planets, nebulae, black holes, clusters, etc. to choose from.

As an example: tonight I had a few minutes to kill so I visited a small desert (Mars-like) planet with a thin ring located in an orbit around dual stars located in a globular cluster. By day, one sun rose and then another. Absolutely scorching the broad plains and distant mountains. Night eventually fell and the sky was burning with the crimson light of the thousands of red giants in the cluster and the brilliant white light of the galactic center. The light was broken slightly by the silhouette of the rings' arc overhead. Was quite beautiful.
