Why Proxima B May Be Far Less Habitable Than We Thought
Four point two light years away, a planet sits in the warm zone of a red dwarf, and every signal we have screams that something is wrong. Proxima b orbits its star in eleven days. One side burns. The other side may have frozen its own air. The star throws flares so violent that one of them, in twenty sixteen, brightened the sky sixty-eight times in seconds. We will visit the killing dose, the missing magnetic shield, the stellar wind that hits like a hurricane, and the laser fleet humans are designing to fly there. If you want the real verdict on the closest Earth-like world, hit subscribe. Strap in. We launch now.
