The debate on whether or not Osiris has water in its atmosphere continues

A new analysis again suggests that gas giant HD209458b currently has water in its atmosphere.  The planet -- nicknamed Osiris -- is 150 light years away from Earth, located in the Pegasus constellation.  The planet was first detected in late November 1999, with the help of astronomical spectroscopy.  

The hot, Jupiter-like gaseous planet has been the target of research once scientists believed water could be located somewhere on the planet.  Three teams of scientists previously believed there could be water in the planet's atmosphere, but those ideas were questioned after the NASA Spitzer Space Telescope was unable to provide evidence.

Travis Bartman, an astronomer working at Lowell Observatory, believes he has discovered the missing water after analyzing the light from a star when it passes through HD209458b's atmosphere.

Barman and researchers from Harvard University measured the light coming from Osiris as it reached the furthest part of the 3.5-day orbit it makes around the star.  With the help of the Hubble Space Telescope, it was possible to further study water absorption in the planet's atmosphere.  Each time the planet passes its parent star, it is possible to analyze how the atmosphere absorbs light passing from the star through the atmosphere.    

Scientists will continue to study and conduct research to either confirm or deny Barman's research.

I wouldn't be true to my form if I didn't chime in and say I, at least, look forward to research like this one day leading to commercial exploitation of Jupiter, its moons, and the other planets of similar composition in the solar system..

Plus, it might mean Jupiter and planets like it would not only be a good place to hide from the Cylon's, but maybe we can also pull water from the atmosphere! Valuable research indeed.

Doh! Forgot about the Cylon factor. How stupid of me. Now it's all clear.

They're counting on your forgetting, of course. Just like the Buggers.

But the real point was, of course, that Jupiter and its entire little system could be commercially exploitable sooner or later. Once lunar operations become common enough I don't see what would stop commercial operations from Jupiter. Assuming, of course, there is something there valuable enough to be worth a round trip, and dealing with apparently wicked radiation.

Wicked radiation....Hmmmm
We could send people with cancer - get radiation treatment for free, actually get paid for treatment. There will not be anything left of your cancer cells after the visit, of course there might not be much left of any other cells. Hey, but what the hell you got to go to Jupiter, see the Giant red spot up close and avoid the Cylons. All in all I say a good deal.
