New research led by NASA Goddard found persistent “erroneous measurements” skewing past estimates for how severe geomagnetic ...

The Sun’s strongest space weather appears to stop suddenly at a specific point in each cycle. The number of sunspots at that ...

The most extreme solar storms to strike Earth could have greater impacts on satellites, power grids and communications than ...

During the Artemis II mission launched Wednesday, NASA will test out a pair of new solar radiation forecasts, developed at University of Michigan Engineering, designed to protect astronauts venturing ...

Space weather warnings could be received hours before Earth is hit rather than minutes with the help of a miniature UK-built ...

Based on previous measurement data, it was thought that there was an upper limit to consequences of a solar storm. Such a ...

A gigantic solar eruption in November 2021 defied expectations. Two spacecraft—Solar Orbiter at 0.85 AU and Wind at 0.98 AU—watched the same coronal mass ejection (CME) as it zoomed through the solar ...

A "cannibal" coronal mass ejection (CME) birthed from a rare type of sunspot will slam into Earth tonight (June 4), likely bringing auroras to skies above 23 U.S. states. The solar outburst began on ...

A solar flare from sunspot 4479 triggered a brief radio blackout over parts of North America and the Pacific. Forecasters are now tracking an Earth-bound coronal mass ejection that could bring a ...

A new NASA-led study suggests future extreme solar storms could be stronger than previously thought, with greater risks for satellites, GPS and power grids.

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

Space travel is, of course, an inherently dangerous undertaking. In addition to concerns about equipment malfunctions and the risks of manufacturing an Earth-like environment in the vacuum of space, ...
