If you think Google Earth is really cool, you’re right: it is!
But imagine in Google Earth to push the globe aside for a moment and within a few seconds travel a few thousand lightyears away to check out a nice star constellation or galaxy over there. This is not possible in Google Earth, but a really nice application exists that can serve as quite a good surrogate to that old boys/girls dream to one day travel the galaxy in a quest very deep into the Unknown.
(‘the Pale Blue Dot’ by Carl Sagan)
This application goes by the really awfull name of ‘Celestia’ and it’s highly recommended to all those that have even the slightest interest in science fiction, space travel and astronomy. You just ‘zap’ through the galaxy, with millions of planets, stars, asteroids, moons and even spacecrafts to discover and explore. It is so awesome to just literaly hop from galaxy to galaxy, a geek’s wet dream.
