Water makes up about 0.25 percent of the molecules in Jupiter's atmosphere along its equator -- almost three times that of the Sun, according to a study based on data from NASA's Juno mission launched in 2011.
The study, published in the journal Nature Astronomy on Tuesday, provided the first findings on the gas giant's abundance of water since the space agency's 1995 Galileo mission.

According to the researchers, including those from NASA's Jet Propulsion Laboratory in the US, Jupiter may be extremely dry compared to the Sun - a comparison based not on liquid water, but on the presence of its components, oxygen, and hydrogen.
