Beyond the habitable zone: Exoplanet atmospheres are next clue to finding life on planets orbiting distant stars

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to its star, water on its ...
