Now that we know the closest star system to us has at least one planet, an Earth-mass and potentially habitable one at that, there is one big question a lot of people are asking: Can […]

Pale Red Dot: Astronomers Discover Potentially Habitable Exoplanet Orbiting Nearest Star

Artist's conception of what Proxima b might look like. It is just slightly more massive than Earth and orbits in its star's habitable zone. Temperatures might allow liquid water to exist on its surface. A potentially habitable world, it is also now the closest known exoplanet. Image Credit:
