Neither link worked for me, but then neither did any links provided via a google search.
I think maybe ESO's site can't handle the traffic.
Regarding the planet around Alpha Cent B.... I always thought all these UFO's and Aliens were coming from somewhere nearby
EDIT: Kevin's link (
http://www.eso.org/public/news/eso1241/) did eventually work for me, took some time and a few refreshes tho.
