Every star sits where its measured parallax puts it. Drag to move, scroll or pinch to zoom, right-drag or Shift-drag (two fingers on touch) to tilt and spin — all the way round, even underneath. Press 3D to flip between overhead and side-on. Click anything, then zoom, to dive straight into it. Keep zooming out — or tap LG, LAN and OBS — to reach the edge of the observable universe.
