The most abundant stars in the galaxy constantly douse their planets with dangerous flares. These dramatic events unleash radiation and charged particlescan that decimate protective atmospheres and destroy any potential life. As a result, even when stars are surrounded by water-rich worlds, scientists wonder whether life could ever thrive in such harsh conditions.
Now new research suggests a rather whimsical form of protection: Hypothetical aliens could shield themselves by shifting the harmful radiation to something more benign, creating a ghostly glow that the next generation of telescopes might even be able to detect. That’s right: glow-in-the-dark aliens.
