What elements are on Europa?

Europa, one of Jupiter's moons, is primarily composed of water ice, with a subsurface ocean believed to exist beneath its icy crust. The surface is also thought to contain various salts and minerals, such as magnesium sulfate and sulfuric acid. Additionally, there may be trace amounts of carbon-based compounds, which could potentially support life. The moon's thin atmosphere is primarily composed of oxygen, though it is not breathable.
