Exoplanet Has Showers of Pebbles

mmmscience writes "The newly-discovered exoplanet COROT-7b has an unusual form of precipitation: rocks. Because it orbits so close to its sun, the temperature on its sun-facing side is around 4220 degrees Fahrenheit. That's hot enough for rocks to vaporize — not unlike water evaporating on Earth. And, like Earth, when the vapor cools in the upper atmosphere, it forms clouds and begins to rain. But instead of water, COROT-7b gets a shower of pebbles."

    That's pretty cool, in a geeky sort of way.

    I wish I could see it... but I don't think the environment would be terribly friendly to my sensitive skin.

    We get solid precipitation here on earth all the time.

    Sometimes it's hail, sometimes sleet.

    The best is frogs, though.

  5. 50% chance of rocking out! by Chris+Burke · · Score: 5, Funny

    It is nearly impossible to imagine a deluge of pebbles falling from the sky, or turning on the morning forecast to hear reports of "rocking" instead of "raining."

    Oh I can imagine it. You see dark clouds roll in, crowding around. In the distance but growing louder, the rapid heavy percussion of the rock shower begins. Then in the cloud at the front, you see a flash of light and a shower of sparks like a pyrotechnic burst. Seconds later, instead of a crash of thunder, you hear the wail of an electric guitar.

    It is now rocking. Rocking hard core.

    This is the awesomest planet ever.
