'Hellhole of the universe' where it rains glass, winds reach 8700kmh and it's 1000 degrees CelsiusESO/M. KORNMESSER HD 189733b - where the winds are ferocious, the heat is extreme and it rains glass - is a mere 63 light years away. Nasa appears to have a soft spot for this exceptionally unpleasant planet, where it rains glass, the wind blows at 8700kmh and temperatures get over 1000 degrees Celsius. Or is it just that, like Earth, when seen from space HD 189733 b is a pretty blue colour? Perhaps the fondness for HD 189733b also has something to do with it being so scientifically useful.
