Sixty-three light-years from Earth, a planet the color of oceans turns out to hold no water at all — only glass. HD 189733b, the first exoplanet to have its visible color directly measured, wears a deep cobalt hue born not of seas but of silicate hazes swirling through a thousand-degree atmosphere scoured by supersonic winds. Its discovery in 2013 offers a quiet but urgent philosophical correction: that beauty at a distance can be a form of deception, and that the most familiar appearances may conceal the most alien realities.
