Space lightning

  1. Apr 18, 2009 #1
    does a phenomena such as lightning happen in the vacuum of space? it's often talks about in sci fi, but i wonder if it actually occurs (theoretically or actually) i tried a google search which turned up nothing.

    No, you do not have opposittely charged clouds which are close enough in space.

    Possible, but, unlikely. The density of interstellar gas and dust is generally insufficient to allow sufficient charges to develope.
