Then felt I like some watcher of the skies; When a new planet swims into his ken*

Below is a photo of a new planet discovered circling the star Fomalhaut 25 light years away. The newly discovered planet is thought to be 3 times the size of Jupiter.

Formalhaut

Jet Propulsion Lab press release here. Don't expect an imminent invastion of Fomalhautians since the star is only 200 to 300 million years old, so there has probably been not enough time for life to arise in that system yet.
