00:00This blue planet looks calm from space, but scientists think glass-like rain may be blown sideways through its atmosphere
00:06by winds around 5,400 miles per hour.
00:10The planet is called HD 189733b.
00:14It is a hot Jupiter.
00:16That means it is a giant gas planet, not a rocky world like Earth.
00:21It sits about 64 light-years away and orbits extremely close to its parent star.
00:26A year there lasts just 2.2 Earth days.
00:30Because it is so close to its star, the atmosphere is blasted by intense heat and radiation.
00:36From far away, the planet appears deep cobalt blue.
00:40But the color does not come from oceans.
00:43Scientists link it to haze and silicate particles high in the atmosphere.
00:47Those particles are why the planet is often described as a world where it may rain glass, not normal rain.
00:54Glass-like material moving through superheated gas.
00:57And if those particles fall, they would not fall straight down like rain on Earth.
01:02The planet's violent winds could drive them sideways through the atmosphere.
01:06Temperatures rise above 1,000 degrees Celsius, making the planet completely hostile to life as we know it.
01:13This is not a calm blue world.
01:15It is a scorching gas giant under extreme conditions.
01:18So from a distance, HD 189733B may look beautiful and peaceful.
01:25But behind that blue glow is brutal wind, extreme heat, and sideways glass-like rain.
01:31We'll see you next time.
