For the first time, astronomers have created a rough map of a planet orbiting a distant sun-like star, employing a technique that may one day enable mapping of Earth-like worlds:
http://www.spaceflightnow.com/news/n0705/09planetmap/ The map revealed a single "hot spot" that is about twice as big as the Great Red Spot on Jupiter and much hotter; the research appearing in the May 10 issue of the journal Nature. -------------------- I always think before posting! - Marco -

Remember, too, that these hot Jupiters are some of the easiest planets to find with our current tools. They may actually be somewhat rare, but since they're the easiest to detect, we're seeing an abnormally large sampling.
It may well be that most solar systems have a fairly recognizable mix of rocky and giant planets, and these fast-orbit hot supermassives are the exception, not the rule. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
