Rains of Terror
If you think a rainy day is a bummer on Earth, just wait till you visit planet HD 189733 b, where it rains glass.
This blue-tinted planet has clouds laced with glass, and its winds cause the glass to rain down at speeds of 5,400 miles per hour (2 kilometers per second) in a sideways spiral. I would not recommend visiting this world, no matter how strong your umbrella.
