Hubble telescope finds cobalt blue planet that rains glass
Next time you want to complain because it's drizzling out, just be happy it isn't glass falling from the sky. The Hubble Space Telescope, which only has three more years of life left in it, was able to get a much better look at a planet outside of our solar system that NASA has been studying for some time.
The planet, named HD 189733b, appears cobalt blue when looked at closely enough. NASA says the planet is constantly raining glass sideways. They think the planet may contain "high clouds laced with silicate particles." The planet is called a "hot Jupiter" as it orbits close to its parent star. That heat, around 2,000 degrees Fahrenheit, causes the silicates to condense.
That's where the winds on the planet, around 4,500 miles per hour, come in, whipping the small pieces of glass throughout the atmosphere, scattering light and making it appear blue.
Suffice to say, it's probably not a good place to set up a new home base. Quite an achievement for the aging telescope, though. Hubble's replacement, the James Webb Space Telescope, will be six times bigger than it's predecessor and is expected to launch in 2018.
