Hubble Finds Wandering Planetoids

Canuckanuck writes: "The Space Telescope Institute which operates the Hubble Telecope has this story about the discovery of an unexpected hereto unknown population of wandering, planet-sized objects in the outer Milky Way that could be 80 times less massive than our beloved Earth. The viewing took place in M22 (a globular cluster) by way of microlensing. These things could be the smallest bodies ever seen beyond our solar system, which don't orbit a star.
