Five years of observations: Starlink satellites grew brighter, while OneWeb got dimmer. It's as if some headlights on the highway blaze brighter while others fade. Such changes threaten to interfere with exoplanet hunters—we might need to rewrite the rules of celestial traffic.

🎯 The astronomical brightness scale works backward: the brighter the object, the smaller its number. So, "a brightness increase of 0.6" means the numerical value dropped by 0.6. This system was invented by ancient astronomers, who divided visible stars into six magnitudes—from first (brightest) to sixth (dimmest).
