Exoplanet HD 189733 b may look like Earth from a distance, but is a nightmarish alien world up close.Astronomers say the planet's weather features deadly winds and "rains of terror."
A far-off exoplanet circling the Earth may appear to be a bright blue similar to the hues of our home planet, but its skies are far from friendly.
“,” wrote NASA in a release.
According to the space agency, exoplanet HD 189733 b’s cobalt blue color comes not from the reflection of a tropical ocean like on Earth, but from a hazy, blow-torched atmosphere that contains high clouds laced with silicate particles.

Rainfall on the planet has been nicknamed the “rains of terror,” as it poses a major threat. NASA describes getting caught in it as “death by a thousand cuts.” Researchers believe that the alien world possibly rains glass sideways.
HD 189733 b’s winds also add to the nightmarish conditions, blowing at seven times the speed of sound and reaching up to 5,400 mph. These killer winds would whip any possible travelers into a spiral around the planet.
, according to Space.com. It’s roughly the size of Jupiter and takes 2.2 days to orbit around the Earth. Its orbit is so close that HD 189733 b is likely tidally locked, which means it always shows one face to its star, similar to how the moon always shows one face to Earth.
HD 189733 b was discovered in December 2005.
