Its a watery world

Its often said that Earth is 70% covered in water, but what if it were 100% covered (and not in the cheesey Kevin Costner way)?  And what if it were 6-7 times larger than it is?  And what if that ocean somehow remained liquid at 200°C...

Wait, what?  200 degrees??!

These are the properties of the latest "exoplanet" to be discovered, by a team at UC Santa Cruz.  An exoplanet is simply a planet in another solar system, and these days there's a veritable flurry of them being discovered.  This latest one in the Ophiuchus system about 42 light years away is the wateriest world yet found and, as far as we know, water is a prerequisite for life, or at least life as we know it.  At 200 degrees its hard to imagine, but with over 400 planets discovered lately, it seems inevitable that the discovery of an earth-like planet - with an earth-like ocean -orbiting a sun-like star is just a doppler shift away.

It doesnt seem that long ago that the idea of planets circling other suns was considered implausible
