Seems those two clever antipodeans have found not just one system but an entire habitable zone, using methods of distance from dangers, chances of
metal dense planets etc.
Theres also a pdf of the full paper published January 2 2004, discribing the methods used and the main area's.
"We modeled the evolution of the Milky Way to trace the distribution in space and time of four prerequisites for complex life: the presence of a
host star, enough heavy elements to form terrestrial planets, sufficient time for biological evolution and an environment free of life-extinguishing
supernovae. We identified the Galactic habitable zone (GHZ) as an annular region between 7 and 9 kiloparsecs from the Galactic center that widens with
time and is composed of stars that formed between 8 and 4 billion years ago. This GHZ yields an age distribution for the complex life that may inhabit
our Galaxy. We found that 75% of the stars in the GHZ are older than the Sun."
Finally theres a movie showing how this "Galactic Habitable Zone" would have developed in our galaxies lifetime. I'm not sure if it was my
connection playing up or a problem with their server, but it took me a while to load.
Anyone that doesn't want to wait for a movie but wishes to see a few high res images.
