(Newser) – Powerful new instruments will help scientists in their search for extra-terrestrial life, the Christian Science Monitor writes.

Most are gas giants but new instruments will help astronomers spot Earth-like planets, and even judge how life-friendly they could be, a task one astronomer called "a priority of enormous resonance, both scientific and emotional."
