Potentially habitable exoplanet candidate spotted around Alpha Centauri A in Earth's backyard

Life on Proxima b: Analyzing the New Earth-like Exoplanet in the Habitable Zone

Proxima Centauri b is one of the most intriguing planets ever discovered. It orbits Proxima Centauri, a small red dwarf star just over four light-years away — the closest known star to our Sun. In cosmic terms, it is practically next door. Yet that short distance hides an almost impossible challenge. The planet is believed to be rocky and roughly similar in size to Earth. Even more striking, it orbits within its star’s habitable zone — the region where temperatures could allow liquid water to ex
