Is this actually H2O water? I read the article but I am still unclear.
I am often excited to hear that water was discovered on some planet or moon but its always a disappointment to learn that its liquid methane or some other liquid that is not actually H2O water.
I think you must be thinking of some other word — maybe the fact that "ice" doesn't necessarily refer to water ice. If a science article says "water," they generally mean water unless the author's phrasing is extraordinarily sloppy.
Water usually means liquid H2O. Europa, for instance, isn't liquid water but ice that is squeezed and loosened to the point it acts like a liquid while still being well below freezing and basically just ice sand
The main part is that they found some type of material that is made of table salt and water https://en.wikipedia.org/wiki/Hydrohalite , real table salt and real water.
