The Schumann resonance is a real electromagnetic hum circling the planet, discovered in 1952 and confirmed in 1960. Here's the physics, and why the wellness claims built on it don't hold up.

NASA, ESA, MIT and University of Arizona scientists agree the space-debris cascade is plausible. They do not agree on whether it has already begun, or how bad it gets from here.

Solar Cycle 25 hit its peak in October 2024, but the history of two previous cycles suggests the biggest flares — and the biggest light shows — can still be ahead in 2026.

Uranus is the only planet that spins on its side. The classic explanation is a violent collision, but a newer theory blames a moon that slowly tilted the planet, then destroyed itself.

A commercial spacecraft is trying to catch a falling NASA telescope before it burns up -- a real-time lesson in why nothing stays in orbit forever.

Three space-weather words get used interchangeably and describe three different things. The sequence, not the synonym, explains what actually reaches the ground.

The $30 million mission is the first attempt by a private spacecraft to capture a U.S. government satellite that was never built to be caught.

NOAA’s Space Weather Prediction Center has issued a G2 geomagnetic storm watch for July 3 after the sun’s biggest flare of the week triggered radio blackouts across North America.

Knuckling shots aren't luck. NASA's wind tunnels and space-station experiments explain how the four-panel Trionda ball swerves through this World Cup.

The rover's laser found large carbon molecules sitting in ancient riverbed rock. What made them, biology or chemistry, is exactly what no one can yet say.

The next great observatory came in by barge, sealed in a case the team calls 'the Chariot,' and ahead of schedule.

The Aeolus orbiter would map Mars's atmosphere daily, but it rides on a rocket Relativity has not yet flown to orbit.

Webb's deepest spectrum of a 'little red dot,' GLIMPSE-17775, points to a supermassive black hole cloaked in dense gas, a possible answer to two cosmic puzzles.

NASA's lunar lander leans on one main engine for descent and ascent. A Chinese engineering team argues that staking astronauts' lives on a single point of failure is a flaw worth fixing.
