Are these planets without orbits? Astronomers have found 10 potential planets as massive as Jupiter wandering through a slice of the Milky Way galaxy, following either very wide orbits or no orbit at all. And scientists think they are more common than the stars. These mysterious bodies, apparently gaseous balls like the largest planets in our solar system, may help scientists understand how planets form. "They're finding evidence for a lot of pretty big planets," said Alan Boss of the Carnegie Institution of Washington, who wasn't involved in the research. |
