IAU 276 The Astrophysics of Planetary Systems: Formation, Structure, and Dynamical Evolution just got underway in Torino, Italy (good week to be in Italy - meeting in Sardinia also, Wish I Was There). 
 
 There are reports from Torino about HARPS observations of Gliese 581(g) 
 
 
 
 Vogt et al reported on additional possible planets in the multi-planet low mass Gliese 581(g) system.
– US-based researchers may have gotten a tad carried away when they announced the discovery of a new, potentially life-sustaining planet a couple weeks back. Yesterday, a team of Switzerland-based astronomers said their own observations of star Gliese 581g didn’t back up the American team at all. “We do not see any evidence for a fifth planet,” astronomer Francesco Pepe told ScienceNow. The team also said that, if they were forced to draw a conclusion from their data, they would get a negative signal, which implies that the planet isn’t there, not that they just haven’t been able to find it, notes Steinn Sigurðsson on his blog. Meanwhile, a member of the US team admits that more data is necessary to confirm Gliese 581g’s existence. “I would expect that on the time scale of a year or two, this should be settled.”
