This illustration shows the Jupiter-sized planet HD 189733b and its parent star. Hubble takes a spectrum of the star HD 189733 and the fully illuminated planet. By subtracting the star's spectrum from the combined spectrum, the spectrum of the planet is obtained. Astronomers now confirm that the planet has an atmosphere containing carbon dioxide. Life as we know it does not exist there, however, because it is just too hot.

Object Name: HD 189733b
