Astronomers spent decades chasing an invisible force pulling our galaxy through space, only to discover it was hidden in plain sight behind cosmic dust.
A cosmic clock reset: Saturn's iconic rings may have formed after the dinosaurs vanished, rewriting what we thought we knew about the solar system's history.
Years ago, before I'd fully learned this lesson, I sat through an entire dinner rehearsing my next point instead of hearing the one being made to me.
A Bell Labs engineer chasing phantom static in 1932 discovered it was keeping time by the stars—and accidentally opened a window onto the cosmos.
The serendipitous discovery that upended astronomy began with what looked like interference—until a graduate student realized the universe was sending a message no one had thought to listen for.
Voyager 1 detects electron oscillations at audio frequencies. The data can be played through a speaker, although the spacecraft is not recording acoustic sound.
Voyager 1 passed Jupiter in 1979 and Saturn in 1980. Its plasma-wave instrument later provided an indirect measurement of electron density beyond the heliopause.
A persistent signal in Bell Labs’ horn antenna survived every equipment check and the removal of pigeon contamination, helping reveal the afterglow of the early universe.
A nation that engineered one of history's most dramatic economic transformations locked an entire generation out of its gains—and now grapples with whether it's too late to fix the bill.
The deadly logic of extreme altitude: ambition and ignorance colliding in a wicker basket thousands of feet above Paris.
The decompression sickness that kills deep-sea divers has a spacewalk equivalent—and it nearly killed test subjects before NASA figured out how to stop it.
The choice between safety and history—a decision one test pilot made at the edge of space with his hand already dying.
A NASA engineer's spacesuit failed at 120,000 feet, his blood began to boil, and he survived to debunk everything we thought we knew about dying in space.
A microscopic creature's superpower against radiation damage could one day shield human cells from cancer treatments, space missions, and environmental hazards.
A spider's web does the job of an eardrum, letting the arachnid sense vibrations in air without ears of its own.
Within a decade, the Moon's natural wobble will conspire with rising seas to flood American streets on clear days—with no storm in sight.
