New cosmic distance record
The other day I mentioned that we may have observed the most distant object in the universe so far. Well, it's been confirmed and the story has made the front page of the BBC news in "Cosmic blast sets distance mark". It's definitely a nice feeling to be the first to detect such a distant object from a ground-based observatory and to do it so quickly after the initial discovery by the Swift satellite. The object has a redshift of 8.2 (a distance of just over 13 billion light years) and blows away the previous redshift record. The press release has more details: "New Gama-Ray Burst smashes cosmic distance record".
