If you look carefully, you'll also noticed one unannounced surprise: Asteroids. For now, they are just for show. If I find time, and if the game is running particularly smoothly, I may start experimenting with Line-of-Sight or Collision, so check back here for such an announcement. For now though, you should be able to just fly over them without any impact on gameplay at all. (Consequently, this is the first time I use the indicator icon for them; I find it is a bit dark, so I may have to lighten it up).
