Four point two light-years away sits a rocky, Earth-sized planet inside the habitable zone of the nearest star to our Sun. NASA called it the most promising candidate for extraterrestrial life ever discovered.
Then the data came in.
Proxima B is tidally locked — one side in permanent daylight, the other in permanent darkness. Its star fires superflares powerful enough to sterilize the surface at least five times a year. The radiation output is one hundred times the lethal dose for the hardiest organism on Earth. And four billion years of flare bombardment may have already stripped the atmosphere entirely.
In this video, we break down the tidal locking, the flare physics, the JWST silence, and why the term "habitable zone" does not mean what you think it means.
