There's a "blue marble" alien planet just 63 light-years from Earth, but the world is anything but friendly to life. Researchers say the blue color in the atmosphere likely comes from a rain of molten glass.
This super hot glass rain is just one consequence of the close proximity between the gas giant alien planet Hd 189733b and its sun. which causes daytime temperatures to soar as high as 1,700 degrees Fahrenheit (930 degrees Celsius), scientists said.
A fresh set of observations of the planet in X-rays also suggest HD189733b has an outer atmosphere that is far larger than expected.
These surprise finds are all signals that so-called hot Jupiter alien planets are worthy of study on their own, even though they are hostile planets to life, researchers said.
