Two news stories today:
The first is not really new news, but the second one is interesting. The planet involved is not suitable for life, but the discovery increases the odds that the conditions for life might exist in other solar systems.
Having actual data on this is relevant to estimates made based on the so-called Drake Equation (for details, look here). Most of the values in that estimate were, basically, wild guesses. The most critical one is the chance that a planet can support life. Data on the odds of finding water available are, therefore, interesting to the SETI community.
