Seven-thousand-kilometre winds sweep silicate glass drops through hot air

HD 189733b is a deep-blue hot Jupiter exoplanet located 64 light-years away. Its atmosphere features temperatures over 900 degrees Celsius and winds howling at 8,700 kilometres per hour. High atmospheric silicate concentrations cause molten glass particles to condense and rain down sideways in violent supersonic storms.
