HD 189733 b
the deep blue planet · it may rain glass
65 light-years from Earth
A gas giant a little bigger than Jupiter. In 2013 Hubble measured its colour: deep blue, probably from a haze of tiny silicate grains, the stuff of sand and glass. Its day side is over 1,000 °C, and winds of several thousand km/h may blow that glass sideways as rain.
