Water, water, everywhere

Within our own solar system, water is surprisingly common. The majority of the surface of our planet is covered in it. Mars has it frozen into the surface. It's found in the atmospheres of all the gas planets. Comets have it in large amounts...

So it's not too much of a stretch to think that it should be abundant elsewhere in the universe (unless our solar system is special for some reason). Water has been detected in interstellar clouds, and now, for the first time on a planet outside our solar system.

Pretty nifty stuff.
