Two Planet Discoveries (four planets)

With the publication of Science today, we get two announcements of the discovery of exoplanets. Hubble has announced the discovery of a planet around the star Fomalhaut (suspected in 2005 but now confirmed) and a team using the Gemini and Keck telescopes have found three planets around the star HR8799. Go over to Sarah for more details.

Funnily enough I was looking at a picture of Fomalhaut's dust disc at Halloween a couple of weeks ago. I suggest the new planet orbiting Fomalhaut be named Planet Sauron.
