Astronomers See the Glow of a Boiling Planet


The Bad Astronomer writes "For the first time, astronomers have detected the light from a 'super-Earth' exoplanet. The planet 55 Cancri e (with twice the radius and 8 times the mass of Earth) circles its host star every 18 hours, and is so hot it glows in the infrared. By observing in that wavelength, the astronomers measured the dip in light as the planet's glow was blocked by the star itself. This is the reverse of the usual method of detecting a planet as it blocks the light of its host star."
