Goldilocks zone Memes

Turns out our definition of "earth-like" is pretty loose in the scientific community. Sure, we've found planets in the habitable zone with rocky compositions, but they're basically just frozen ice daggers or molten lava hellscapes. "Similar mass and orbital characteristics" doesn't quite capture the nuance of "not actively trying to murder any life form that might evolve there." Next time you hear about an exciting new exoplanet discovery, remember that "potentially habitable" is scientist-speak for "probably won't instantly kill you, but good luck surviving longer than 3 seconds."

The haircut literally resembles the narrow habitable zone of a tidally-locked exoplanet—that thin strip between eternal scorching daylight and freezing darkness where liquid water might exist. Astronomers spend decades searching for these cosmic Goldilocks zones, only for this guy to wear one on his head. The barber understood the assignment with surgical precision. Next time I publish in The Astrophysical Journal , I'm using this as my author photo.
