Cobalt-blue world with molten glass rain 63 light-years away
TL;DR Summary
HD 189733b, a tidally locked hot Jupiter about 63 light-years away, appears cobalt blue because its atmosphere scatters blue light from molten silicate droplets; daytime temperatures exceed 1,000°C and winds reach around 7,000 km/h, driving continuous horizontal rain of glass droplets. The planet has no oceans, and its color was inferred from secondary eclipse spectroscopy rather than direct imaging.
- There is a planet 63 light-years from Earth where the rain is made of molten glass, the winds blow at 7,000 kilometres per hour, the daytime temperature is over 1,000 degrees Celsius, and the planet itself, viewed from space, is the same deep blue as Earth. Space Daily
- About 63 light-years away there is a deep-blue world that looks deceptively like Earth from a distance, but on the planet HD 189733b the temperature reaches 2,000 degrees Fahrenheit and the winds scream at thousands of miles an hour Space Daily
