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]:

• Cathy Plesko, an applied physicist from Los Alamos National Laboratory. Cathy uses supercomputers to model what happens when an asteroid hits a planet.
• Peter Thelin, a master optician from Lawrence Livermore National Laboratory. Peter's expertise is cutting and shaping materials by hand so they can be used by Lawrence Livermore researchers to explore the universe.
• Chris Ebbers, a physicist from Lawrence Livermore. Chris uses lasers to study crystals.
• Vishal Patel, a researcher from Idaho National Laboratory’s Center for Space Nuclear Research. Vishal studies how new forms of nuclear power could fuel tomorrow’s spacecraft.
