I was just searching around internet to see if there is some good website that shows good pictures of outer space, and I came across Celestia. When I read about Celestia, I was completely amazed. It is such an amazing free software, that I was surprised I had not heard about Celestia before. Celestia was made in 2001, and it soon grabbed the attention of space lovers.
