So you can see gorgeous, space porn in HD color using space telescopes. What else is new? We can see OTHER earth-like planetary systems, floating planets with no stars, Goldilocks planets where life and even alien civilization is possible. Dig it? There is still so much to learn from observing and studying the stars. And HD images of Nebula do make for some of the best posters you can put together for both your desktop or for your room if love space imagery or are a sci-fi fan.
