Even Florida got to see the Northern Lights in all their glory; well, that’s a plot twist if there ever was one. A very rare G4-level geomagnetic storm painted hues of bright green, purple, and red ...

New observations track coronal mass ejections nearly all the way from the Sun to Earth, improving forecasts tenfold ...

Researchers led by the University of Iowa documented the rapid growth using observations from two spacecraft positioned along ...

Two solar eruptions launched on October 7 and 8 could merge as they travel towards Earth, raising concerns about further geomagnetic storm activity on October 11, 2026.

Using continuous imagery from NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, scientists predicted the near-Earth arrival of a solar eruption to within 30 minutes in an initial ...

A restless Earth-facing sunspot has been firing off a barrage of powerful solar flares — and now a CME could be heading our way.

A coronal mass ejection left the sun Tuesday in the wake of a solar flare, which could mean displays of aurora on Friday, say space weather experts.

In March 2025, NASA launched the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission in an effort to better understand solar weather. It consists of a constellation of four microsatellites ...

A fresh eruption from Sunspot 4549 has sent a Moreton wave and a coronal mass ejection into space. Forecasters say the incoming solar material could trigger geomagnetic storms, brighter auroras and ...

Why coronal mass ejections and late-cycle flares pose surprise threats to modern tech Illustrative image. When the CMEs (coronal mass ejection) slam into Earth's magnetosphere, they can create ...

The satellite that warned the world about every major geomagnetic storm for more than a decade was quietly retired last month, and its replacement is now being put to work for the first time tonight.

A powerful solar eruption recorded on 8 October could trigger a moderate geomagnetic storm on 11 October, NOAA has warned. The event may brighten auroras but could also affect satellite signals, radio ...
