Okay kids, time to explore the universe without having to move your lazy butt out of your chair. Celestia is amazing! And it's free! And it's on Mac, Windows, and Linux. And if 100,000 stars isn't enough, it's expandable. Explore through our lowly solar sytem or branch outward to our galaxy and beyond. And you can move through space... and time.
How good is it? Top Men will let you decide. We found a couple recent Cassini images, entered the date they were taken into Celestia, set the location as Cassini and the target as Saturn. You have to decide which is the Celestia image and which is the real one from the pairs above.
Clicking on the pair will link to the actual Cassini image.
