New planets discovered.

I can understand that we can see other planets. I can understand that we can know how far away they. What I can't understand is how scientists can tell me with certainty that a planet light years away has "surfaces hotter than molten lava" or "a planet with the density of Styrofoam" thats larger than our own Jupiter. How about "two inexplicable planet-sized objects that for some reason are hotter than the stars they orbit."

Can anyone show me the math?
