Or because the Coalition was closer and had more potentially habitable real estate?

The right star system (including organics and potentially habitable planets)

Fifty-four sounds titillatingly high when it refers to the number of newly discovered planets that are potentially habitable.

If confirmed, this would be the first strong case for a potentially habitable Earth-like exoplanet yet discovered.

It will characterise these worlds, all thought to have significant bodies of liquid water beneath their surfaces, as potentially habitable environments.

The discovery of Gliese 581 g raises hopes of finding more red dwarf systems, including potentially habitable ones.

Fortunately, by that point, several international blocs' initial probes had established a surprising number of interesting and potentially habitable worlds out there.

Such observational refinements may allow us to better gauge how common potentially habitable worlds are.

The discovery raises the hopes of planet hunters that if they keep working they will find more and more potentially habitable systems like our own.

In recent years, the search for potentially habitable planets outside our solar system has stepped up several gears.
