Mars has often been compared to deserts on Earth, and for good reason: It is pretty much a barren landscape with a lot of sand and rocks everywhere. Sometimes the similarities can be quite striking, and […]

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: ESO/M. Kornmesser

Astronomers today announced […]
