An article in today's WaPo says the Kepler telescope is detecting all kinds of fascinating things, including new "exoplanets":
For example, Kepler found a star with a small orbiting object that is hotter than the star itself. The object is too hot to be a planet but is the wrong size and density to fit any known profile for a dwarf star.
One of the five planets announced by William J. Borucki, the top scientist for the telescope, is so fluffy that "it has the density of Styrofoam," he said.
Fluffy planet!
man, i’d like to know how the gravity works on a planet with the density of styrofoam!
and is it possible these things might not be planets but something… other?
Styrofoam planet? sounds like something from a Robert Sheckley novel, or Douglas Adams.
