In late summer of 1859, the sun unleashed one of the most powerful geomagnetic storms ever recorded. Auroras normally ...

A "cannibalistic" solar storm is about to slam into Earth's magnetic field, triggering vibrant auroras that will potentially be visible in up to 18 different U.S. states, just in time for Labor Day.

Our sun is capable of storms far bigger than we’ve ever recorded. Studying the world’s oldest trees suggests we could be due one of these gargantuan events soon ...

In March 2025, NASA launched the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission in an effort to better ...

Risks of potentially devastating solar storms may be underestimated, warns a new study. And the effects of extreme space weather on life on Earth may be larger than previously thought, say scientists.

Solar storm forecasting took a tenfold leap with NASA's PUNCH satellite constellation, which predicted a G4-class storm's ...

The effects of extreme space weather may be larger than previously thought, research in the journal Nature reveals. The paper, titled "Regression to the mean can explain saturation of geomagnetic ...

The Sun's most extreme storms may be far more powerful than scientists currently plan for. New research led by physicists at NASA's Goddard Space Flight Center, published in Nature on July 19, found ...

In May 2024, the strongest geomagnetic storm in two decades exposed important gaps in how the UK monitors and prepares its ...

A geomagnetic storm is hitting Earth right now. NOAA's Space Weather Prediction Center confirmed G1 (minor) geomagnetic storm conditions through Wednesday after fast solar wind from a large coronal ...

Scientists have long assumed that there’s an upper limit to the intensity of the solar winds that reach Earth. New research suggests there’s not—and the implications are alarming. Solar storms occur ...
