The aurora displays that were supposed to accompany last night's lunar eclipse apparently weren't cancelled, but only delayed ...

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 ...

A team at the Applied Physics Lab is working to understand the complex science behind predicting invisible threats that can quickly cripple electric grid infrastructure on Earth. On the morning of ...

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 northern lights could mean lights out for the infrastructure we rely on.

New research led by NASA Goddard found persistent “erroneous measurements” skewing past estimates for how severe geomagnetic storms can get. Reading time 3 minutes Cataclysmic solar storms may be rare ...

Solar storms have long been treated as a hazard to satellites, power grids, and GPS systems. A peer-reviewed study published in Geophysical Research Letters this spring adds a category that no ...

Researchers have proposed an unorthodox way to shield our planet from the constant barrage of solar storms — launching a giant satellite “airbag” into space to mitigate their worst effects. This ...
