A ghost is the apparition of a being that is not really there. A ghost apple is the same, made of ice, although the apples were there once. Ice covered the apple trees in an orchard in western Michigan. When Andrew Sietsema went out to prune the trees, he saw -and photographed- apples of ice.

“I guess it was just cold enough that the ice covering the apple hadn’t melted yet, but it was warm enough that the apple inside turned to complete mush (apples have a lower freezing point than water),” Sietsema told CNN.
“And when I pruned a tree it would be shaken in the process, and the mush would slip out of the bottom of the ‘ghost apple.'”
Precise weather conditions create all kind of amazing phenomena we wouldn’t believe if people didn’t have cameras ready to give us evidence. See more pictures of the ghost apples at CNN. -via Metafilter
