The discovery of Gliese 581g was cause for rampant hype almost everywhere but here, along with some rather ridiculous claims that there was a 100% chance of life there.

The actual paper authors were more reserved, though astronomy is far bolder than biology in terms of its participants hyping findings and generally physics is pretty reserved (exception: LHC claims when it was being funded and built - now that the marketing is over, the call for perspective has set in) outside dark matter and dark energy, where anything goes.
