Maybe That Galaxy

Is Not So Far Away

* What parts of the "Star Wars" movies are science and what parts are fiction?

An exhibit opening today at the Museum of Science in Boston, Massachusetts, has answers that might surprise you. "Star Wars: Where Science Meets Imagination" features lots of really cool stuff for "Star Wars" fans, including a collection of light sabers, Darth Vader's helmet (all three parts) and a "naked" C-3PO.

But what makes the exhibit really amazing is the way it takes scenes from the six movies and explains how real-world science makes some of the movie magic real. Find out how similar Anakin's mechanical arm is to high-tech replacement arms being used today. You also can ride a replica of Han Solo's Millennium Falcon and discover how Tatooine, Hoth and Mustafar resemble real planets -- and even Earth at different stages of its development.

Interactive exhibits let you build a hovercraft with Lego and magnets, and then watch it fly. Or you can create a robot and figure out what it takes to make it walk without toppling over.

The exhibit is in Boston through April. The tour doesn't come to Washington but will stop in Philadelphia, Pennsylvania. That's just a quick landspeeder ride away, right?
