Without enough liquid water on the surface, a planet's
atmosphere can become choked with carbon dioxide, raising temperatures to a
level beyond what is survivable for all known life
Is water important for life on exoplanets? According to Genesis, it is important also in space in which God created the planets.
Alien worlds found in the “habitable zone” of their
star may still not be right for life

The number
of planets capable of hosting alien life may be smaller than we thought, thanks
to a new understanding of how water levels drive a planet’s climate. Below a
certain level, carbon dioxide in the atmosphere can grow too much and make a
planet unbearably hot, which could also explain why Venus is as inhospitable as
it appears today.
All life
that we know of needs liquid water, which is why astronomers are keen to find
planets in the “habitable zone” around their star region where temperatures are
conducive for liquid water to exist. But now Haskelle White-Gianella at
the University of Washington and her colleagues have found that source;
