Essential chemical elements and sources of energy, two of [ the ] three requirements for life, are found all over the solar system. But the third — liquid water — is somewhat hard to find beyond Earth, while scientists have not yet detected liquid water directly, we've found the next best thing : water in vapor form.

For me, the interesting thing about this work is not only the first direct detection of water above Europa, but also the lack thereof within the limits of our detection method.
