'Hot Jupiter' Systems May Harbor Earth-like Planets
'Hot Jupiter' Systems may Harbor Earth-like Planets. The catalogue of confirmed extrasolar planets ('exoplanets') is growing rapidly. There are currently approximately 133 known planetary systems, harboring a total of 156 exoplanets as of January 2006*. With regard to the search for life-sustaining worlds, however, the results have been disappointing. Most of the exoplanets identified so far are so-called "hot Jupiters", gas giants in a stable orbit very close to their star. Stellar systems with a hot Jupiter were once thought to be incapable of forming Earth-like planets, but suprising new evidence indicates otherwise. [Physics Org]
