Science
Using Hubble and Spitzer space telescopes, scientists studied the "hot Saturn" called WASP-39b and by dissecting starlight filtering through the planet's atmosphere into its component colors, they found clear evidence for a large amount of water vapor, almost three times as much water as our Saturn does.
Space
The presence of titanium oxide gives the planet a shield layer like the ozone layer of earth which prevents heat to come inside or escape the atmosphere.
