Wandering Mystery Planets?

"Wandering Mystery Planets
NASA's Hubble Space Telescope has spotted what seem to be strange planet-sized objects wandering loose in globular cluster M22."

Interesting topic from our friends at NASA, though the article is dusty.

"So what are they? Theoretically, planets can be gravitationally torn from their parent stars in the cluster to form a population of wanderers. But, say researchers, that explanation won't work. The planet-sized mystery bodies in M22 could make up as much as 10 percent of the cluster's mass. They are too numerous to have once been parts of normal planetary systems."
