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.

This is just a first step. Proof that another planet was water. They started with large planets because they are much easier to detect at a range of millions of miles. Now that they know a "jupiter like" planet has water we likely will find another earth like planet with water in the future. The first is always the hardest. It's like saying man that first CPU sucked because it only ran 3mhz and you can't play Quake on it. If it hadn't been created nothing after it would have come along.

Well thanks to: Masher2, PlasmaBomb, namechamps, and a point made by etsp, I feel a little wiser today. Either it's been to many years since I had a science class, guess near 17 years, or theories (back then) have changed or been corrected. Thanks for clarifying my question on the value of this study.

Everyday you learn something new, and hopefully it makes you a better person and the world a better place. That is why people do research on numerous subjects.
