Scaffolding
Weak gravitational lensing: invisible dark matter revealed through coherent galaxy shapes. Based on Scognamiglio et al. (Nature Astronomy, Jan 2026), who used JWST's COSMOS-Web survey to create the most detailed dark matter map ever — 800,000 galaxies, 255 hours of observation, twice the resolution of Hubble. The galaxies aren't randomly oriented. They're all slightly stretched by the same invisible structure. That coherence is the signal.
Lensing
Gravitational microlensing: an invisible object reveals itself by bending starlight. Based on Dong et al. (Science, 2026), who measured a rogue planet's mass for the first time using stereoscopic parallax between Earth and the Gaia spacecraft. A Saturn-mass world, ejected from its birth system, wandering alone 10,000 light-years away — detected only by the light it bends.
Cosmic Mistake
Why your zodiac sign—that thing that supposedly defines your personality—is probably wrong. Sorry, Gemini.
