"HD 189733 b is an exoplanet approximately 64.5 light-years away from the Solar System in the constellation of Vulpecula.
....Some of the most terrifying and mind-blowing destinations in our galaxy.
In this image, the nightmare world of HD 189733 b is the killer you
never see coming. To the human eye, this far-off planet looks bright
blue.
But any space traveler confusing it with the friendly skies of
Earth would be badly mistaken. The weather on this world is deadly.
Its
winds blow up to 5,400 mph at seven times the speed of sound,
whipping all would-be travelers in a sickening spiral around the planet.
-x-And getting caught in the rain on this planet is more than an
inconvenience; it’s death by a thousand cuts. This scorching alien world
possibly rains glass—sideways—in its howling winds.
-x-The cobalt blue
color comes not from the reflection of a tropical ocean, as on Earth,
but rather a hazy, blow-torched atmosphere containing high clouds laced
with silicate particles."
