There Is a Planet Where It Rains Glass Sideways
A blue alien planet with visible horizontal streaks of glittering glass rain being blown across its turbulent atmosphere
HD 189733b, located 63 light-years away, has winds exceeding 8,700 kilometers per hour that blow molten silicate glass horizontally. The planet appears deep blue, not from water, but from the light-scattering properties of the glass particles in its atmosphere.
Why Itβs Interesting
It redefines what 'weather' can mean. On Earth we worry about rain; on HD 189733b, you would be shredded by horizontal glass shards moving at seven times the speed of sound. It makes Earth's worst hurricanes look gentle by comparison.
