On exoplanet HD 189733b, 64 light years away, the weather forecast is glass rain blown sideways at 5,400 mph. It is a hot Jupiter, tidally locked with one side always facing its star, reaching over 1,000°C. NASA's Hubble discovered its deep blue colour comes not from oceans but from silicate particles in the atmosphere that condense into glass. High winds whip those molten glass shards into horizontal storms. It is beautiful from afar and absolutely lethal up close, a reminder how wild planets can be.
