"Have we ever put people back on the moon since Apollo? I was just curious if there were plans to ever go back. Never hear anything about it."
  1. PAH's Responsible for "Red Glow"

    New work from NAI NASA Ames Research Center Team members and their colleagues published recently in PNAS suggests that the cause for much of the extended red emission, or ERE, is due to closed-shell cationic polycyclic aromatic hydrocarbon, or PAH, dimers. Their work sheds light on the processes involved in carbonaceous dust evolution in the interstellar medium.
