They're filming some scenes for the new J.J. Abrams "Star Trek" movie at Lawrence Livermore Laboratory this week.
The Lab is located at 7000 East Ave # B663-L72, Livermore, CA. We do hear that it's pretty much impossible to get on site. But you may be able from outside the facility
"The segments are being filmed in the lab's National Ignition Facility, or NIF, said Dale Kaye, president of the Livermore Valley Chamber of Commerce and a Livermore Valley film commissioner. The NIF building can fit three football fields and is where scientists are using ultraviolet laser light from the world's largest laser to produce thermonuclear ignition at temperatures and densities similar to those in the sun."
