City Lights Spotted on Proxima B! Have We Found Neighbors?

Proxima Centauri b has captured worldwide attention because it is the closest known potentially Earth-like planet ever discovered. Located just 4.24 light-years away, the world is roughly similar in size to Earth and orbits within the habitable zone of its star, where conditions could potentially allow liquid water to exist. Its discovery marked a major milestone in the search for planets that may host life beyond our solar system.
