Well, not quite, but I’m surprised this story hasn’t got more publicity:
Osiris, which is 150 light years from Earth and has the official title HD 209458b, was the first extra-solar world known to have an atmosphere, mainly composed of hydrogen. But its atmosphere was found to be boiling away into space.
In 2004, astronomers revealed that the planet’s outer atmosphere contained carbon and oxygen, thought to be swept up from the deeper levels by the flow of escaping hydrogen. The new discovery of water vapour emerged from measurements taken as Osiris passed directly in front of its parent star
