SUMMARY
The recent discovery of Proxima b, a terrestrial planet with a minimum mass of 1.3 Earth masses, orbits the red dwarf star Proxima Centauri at a distance conducive to liquid water. This finding, published in Nature, indicates that Proxima b's equilibrium temperature may allow for habitable conditions, despite challenges such as its 11-day orbital period and potential tidal locking. The planet's atmosphere, if present, could mitigate radiation from Proxima Centauri's flares, raising the possibility of life. Future observations, particularly with the James Webb Space Telescope, aim to characterize Proxima b's atmosphere and assess its habitability.
