Gliese 581 g is now officially confirmed
Well, there's new evidence pointing to its existence and upholding the original findings, but that's not quite the same thing as being "officially confirmed". The new supporting data is from the same team that originally announced the discovery. It would be more compelling if an unrelated group made a similar announcement. And it would also help if the false-positive probability were lower.
But hopefully this will lead to an official confirmation.
