This discovery about sub-surface oceans on Europa is based on data from the Hubble. If we did have the TMT, it would be 10x more powerful and we would know even more about Europa, among other things.
FYI -- here's a detailed article showing some of the plumes on Europa. http://www.nasa.gov/press-release/nasa-s...oon-europa
Hubble spotted plumes nearly 5 years ago. We've suspected there's water there for about 30 years since the Voyager flyby and we also know from Cassini showed evidence of water on Enceladus a few years back too.
