ExoPlanets: HD 189733 b
This far-off blue planet may look like a friendly haven β but donβt be deceived! Weather here is deadly. The planetβs cobalt blue color comes from a hazy, blow-torched atmosphere containing clouds laced with glass. Howling winds send the storming glass sideways at 5,400 mph (2km/s), whipping all in a sickening spiral. Itβs death by a million cuts on this slasher planet!
