It’s #SpaceWeek on Energy.gov. Throughout the week, we’ll be exploring energy and science on the cosmic frontier. Tune in on Twitter, Facebook, Google+ and Instagram.

We often talk with experts about how energy works on Earth. But what if they could use their knowledge to discuss how energy works in a galaxy far far away? Star Wars fans, this one’s for you.

How much energy would it take to run a Death Star? What type of energy source could power a lightsaber? Experts from the Department of Energy’s National Laboratories are here to answer these questions and more about energy in the Star Wars films. Have a question of your own? Ask on social media using #StarWarsEnergy, or send us an email at newmedia@hq.doe.gov.

[Yoda voice]Answer your questions, these experts will. Hmm.[/Yoda voice]:
