Water Outside the Solar System

This article is interesting in that we have now finally found water on a planet outside the solar system. What is strange to me about it, is that the planet in question is extremely close to its star. It orbits every 3.5 days. I would have thought the water would have boiled away from the heat. Apparently it has not. Scientists used a model to predict the presence of water and then compared it with readings of the planet. So, assuming that the model is correct, an extra-solar planet has water. This means that water may be more common on planets than previously thought. Hence the possibilities for life may be greater than previously thought, if water is a requirement for life (or at least a great help).
