Celestia

I found out about long before I started blogging, so I've had it for a while. Bassicly, it's a grand tuor of the universe. You can fly around in your spaceship to anywhere, at any speed possible. You can make time go fast and see the planets rotate, have time go as it is (the planets still rotate, but too slow to notice,) or pause time all together. My only critique on it is that it dosen't have nebulas, which in my opinion are the most beutiful things in the universe.
