could have liquid water, not necessarily that it is the kind of place
any human would like to inhabit. For example, the article is most-

It doesn't even really mean that - it just means that they are in the habitable zone. Planets in the habitable zone could be Luna-like rockballs, small gas giants, venus-like hellholes, on eccentric orbits, or anything else that could preclude actual 'habitability'. It certainly doesn't mean that they're 'shirtsleeve environments' (particularly given the limited range of pressures and atmospheric conditions that humans are comfortable in).
