A monochrome photo of the Stanford Dish: a giant, upward-pointing, 150 foot in diameter radio antenna set against bright gray skies. The mesh steel dish is a familiar sight to people driving Interstate 280 through the rolling, grass and tree-lined hills behind Stanford University. Wikipedia says the dish was once used for detecting Soviet radar installations by monitoring signals bounced off the moon. Later, it was used for satellite communications... and now is used for "academic and research purposes." No spooky, hidden spy stuff there, right?
