We still teach that the search for life elsewhere in the universe is he essentially a search for water in its liquid form. This seems based on sound principals- every form of life we know of requires water. New research is turning up more opportunities for life though.

Water still is a vital element, but this result shows that somewhere life may have formed without access to liquid water, meaning the search to ET can widen.
