The planet known for raining glass is HD 189733b, a "hot Jupiter" gas giant located about 63-64 light-years from Earth. This exoplanet experiences extreme weather conditions where molten glass shards rain sideways due to supersonic winds reaching speeds up to 5,400 mph (8,700 km/h). The intense heat, with temperatures soaring over 1,700°F (930°C), and the presence of silicate particles in the atmosphere create glass clouds that scatter blue light, giving the planet its striking cobalt blue color. The violent winds carry these molten glass shards across the atmosphere, making it a hostile and deadly environment
. Additionally, HD 189733b has been found to have an atmosphere containing hydrogen sulfide, which gives it a smell akin to rotten eggs, further highlighting its extreme and unusual atmospheric chemistry
. In summary, HD 189733b is the planet famous for its molten glass rain driven by fierce winds and scorching temperatures, making it one of the most extreme and fascinating exoplanets studied by astronomers.
